+/**
+ `AFHTTPSessionManager` is a subclass of `AFURLSessionManager` with convenience methods for making HTTP requests. When a `baseURL` is provided, requests made with the `GET` / `POST` / et al. convenience methods can be made with relative paths.
+
+ ## Subclassing Notes
+
+ Developers targeting iOS 7 or Mac OS X 10.9 or later that deal extensively with a web service are encouraged to subclass `AFHTTPSessionManager`, providing a class method that returns a shared singleton object on which authentication and other configuration can be shared across the application.
+
+ ## Methods to Override
+
+ To change the behavior of all data task operation construction, which is also used in the `GET` / `POST` / et al. convenience methods, override `dataTaskWithRequest:uploadProgress:downloadProgress:completionHandler:`.
+
+ ## Serialization
+
+ Requests created by an HTTP client will contain default headers and encode parameters according to the `requestSerializer` property, which is an object conforming to `<AFURLRequestSerialization>`.
+
+ Responses received from the server are automatically validated and serialized by the `responseSerializers` property, which is an object conforming to `<AFURLResponseSerialization>`
+
+ ## URL Construction Using Relative Paths
+
+ For HTTP convenience methods, the request serializer constructs URLs from the path relative to the `-baseURL`, using `NSURL +URLWithString:relativeToURL:`, when provided. If `baseURL` is `nil`, `path` needs to resolve to a valid `NSURL` object using `NSURL +URLWithString:`.
+
+ Below are a few examples of how `baseURL` and relative paths interact:
+
+    NSURL *baseURL = [NSURL URLWithString:@"http://example.com/v1/"];
+    [NSURL URLWithString:@"foo" relativeToURL:baseURL];                  // http://example.com/v1/foo
+    [NSURL URLWithString:@"foo?bar=baz" relativeToURL:baseURL];          // http://example.com/v1/foo?bar=baz
+    [NSURL URLWithString:@"/foo" relativeToURL:baseURL];                 // http://example.com/foo
+    [NSURL URLWithString:@"foo/" relativeToURL:baseURL];                 // http://example.com/v1/foo
+    [NSURL URLWithString:@"/foo/" relativeToURL:baseURL];                // http://example.com/foo/
+    [NSURL URLWithString:@"http://example2.com/" relativeToURL:baseURL]; // http://example2.com/
+
+ Also important to note is that a trailing slash will be added to any `baseURL` without one. This would otherwise cause unexpected behavior when constructing URLs using paths without a leading slash.
+
+ @warning Managers for background sessions must be owned for the duration of their use. This can be accomplished by creating an application-wide or shared singleton instance.

As such, it is not recommended that you throttle bandwidth based solely on network reachability.

+/**
+ `AFURLSessionManager` creates and manages an `NSURLSession` object based on a specified `NSURLSessionConfiguration` object, which conforms to `<NSURLSessionTaskDelegate>`, `<NSURLSessionDataDelegate>`, `<NSURLSessionDownloadDelegate>`, and `<NSURLSessionDelegate>`.
+
+ ## Subclassing Notes
+
+ This is the base class for `AFHTTPSessionManager`, which adds functionality specific to making HTTP requests. If you are looking to extend `AFURLSessionManager` specifically for HTTP, consider subclassing `AFHTTPSessionManager` instead.
+
+ ## NSURLSession & NSURLSessionTask Delegate Methods
+
+ `AFURLSessionManager` implements the following delegate methods:
+
+ ### `NSURLSessionDelegate`
+
+ - `URLSession:didBecomeInvalidWithError:`
+ - `URLSession:didReceiveChallenge:completionHandler:`
+ - `URLSessionDidFinishEventsForBackgroundURLSession:`
+
+ ### `NSURLSessionTaskDelegate`
+
+ - `URLSession:willPerformHTTPRedirection:newRequest:completionHandler:`
+ - `URLSession:task:didReceiveChallenge:completionHandler:`
+ - `URLSession:task:didSendBodyData:totalBytesSent:totalBytesExpectedToSend:`
+ - `URLSession:task:needNewBodyStream:`
+ - `URLSession:task:didCompleteWithError:`
+
+ ### `NSURLSessionDataDelegate`
+
+ - `URLSession:dataTask:didReceiveResponse:completionHandler:`
+ - `URLSession:dataTask:didBecomeDownloadTask:`
+ - `URLSession:dataTask:didReceiveData:`
+ - `URLSession:dataTask:willCacheResponse:completionHandler:`
+
+ ### `NSURLSessionDownloadDelegate`
+
+ - `URLSession:downloadTask:didFinishDownloadingToURL:`
+ - `URLSession:downloadTask:didWriteData:totalBytesWritten:totalBytesExpectedToWrite:`
+ - `URLSession:downloadTask:didResumeAtOffset:expectedTotalBytes:`
+
+ If any of these methods are overridden in a subclass, they _must_ call the `super` implementation first.
+
+ ## Network Reachability Monitoring
+
+ Network reachability status and change monitoring is available through the `reachabilityManager` property. Applications may choose to monitor network reachability conditions in order to prevent or suspend any outbound requests. See `AFNetworkReachabilityManager` for more details.
+
+ ## NSCoding Caveats
+
+ - Encoded managers do not include any block properties. Be sure to set delegate callback blocks when using `-initWithCoder:` or `NSKeyedUnarchiver`.
+
+ ## NSCopying Caveats
+
+ - `-copy` and `-copyWithZone:` return a new manager with a new `NSURLSession` created from the configuration of the original.
+ - Operation copies do not include any delegate callback blocks, as they often strongly captures a reference to `self`, which would otherwise have the unintuitive side-effect of pointing to the _original_ session manager when copied.
+
+ @warning Managers for background sessions must be owned for the duration of their use. This can be accomplished by creating an application-wide or shared singleton instance.

+ 
+ When implementing an authentication challenge handler, you should check the authentication method first (`challenge.protectionSpace.authenticationMethod `) to decide if you want to handle the authentication challenge yourself or if you want AFNetworking to handle it. If you want AFNetworking to handle the authentication challenge, just return `@(NSURLSessionAuthChallengePerformDefaultHandling)`. For example, you certainly want AFNetworking to handle certificate validation (i.e. authentication method == `NSURLAuthenticationMethodServerTrust`) as defined by the security policy. If you want to handle the challenge yourself, you have four options:
+ 
+ 1. Return `nil` from the authentication challenge handler. You **MUST** call the completion handler with a disposition and credentials yourself. Use this if you need to present a user interface to let the user enter their credentials.
+ 2. Return an `NSError` object from the authentication challenge handler. You **MUST NOT** call the completion handler when returning an `NSError `. The returned error will be reported in the completion handler of the task. Use this if you need to abort an authentication challenge with a specific error.
+ 3. Return an `NSURLCredential` object from the authentication challenge handler. You **MUST NOT** call the completion handler when returning an `NSURLCredential`. The returned credentials will be used to fulfil the challenge. Use this when you can get credentials without presenting a user interface.
+ 4. Return an `NSNumber` object wrapping an `NSURLSessionAuthChallengeDisposition`. Supported values are `@(NSURLSessionAuthChallengePerformDefaultHandling)`, `@(NSURLSessionAuthChallengeCancelAuthenticationChallenge)` and `@(NSURLSessionAuthChallengeRejectProtectionSpace)`. You **MUST NOT** call the completion handler when returning an `NSNumber`.
+ 
+ If you return anything else from the authentication challenge handler, an exception will be thrown.
+ 
+ For more information about how URL sessions handle the different types of authentication challenges, see [NSURLSession](https://developer.apple.com/reference/foundation/nsurlsession?language=objc) and [URL Session Programming Guide](https://developer.apple.com/library/content/documentation/Cocoa/Conceptual/URLLoadingSystem/URLLoadingSystem.html).

+         iOS 7 and iOS 8 differ in NSURLSessionTask implementation, which makes the next bit of code a bit tricky.
+         Many Unit Tests have been built to validate as much of this behavior has possible.
+         Here is what we know:
+            - NSURLSessionTasks are implemented with class clusters, meaning the class you request from the API isn't actually the type of class you will get back.
+            - Simply referencing `[NSURLSessionTask class]` will not work. You need to ask an `NSURLSession` to actually create an object, and grab the class from there.
+            - On iOS 7, `localDataTask` is a `__NSCFLocalDataTask`, which inherits from `__NSCFLocalSessionTask`, which inherits from `__NSCFURLSessionTask`.
+            - On iOS 8, `localDataTask` is a `__NSCFLocalDataTask`, which inherits from `__NSCFLocalSessionTask`, which inherits from `NSURLSessionTask`.
+            - On iOS 7, `__NSCFLocalSessionTask` and `__NSCFURLSessionTask` are the only two classes that have their own implementations of `resume` and `suspend`, and `__NSCFLocalSessionTask` DOES NOT CALL SUPER. This means both classes need to be swizzled.
+            - On iOS 8, `NSURLSessionTask` is the only class that implements `resume` and `suspend`. This means this is the only class that needs to be swizzled.
+            - Because `NSURLSessionTask` is not involved in the class hierarchy for every version of iOS, its easier to add the swizzled methods to a dummy class and manage them there.
+        
+         Some Assumptions:
+            - No implementations of `resume` or `suspend` call super. If this were to change in a future version of iOS, we'd need to handle it.
+            - No background task classes override `resume` or `suspend`
+         
+         The current solution:
+            1) Grab an instance of `__NSCFLocalDataTask` by asking an instance of `NSURLSession` for a data task.
+            2) Grab a pointer to the original implementation of `af_resume`
+            3) Check to see if the current class has an implementation of resume. If so, continue to step 4.
+            4) Grab the super class of the current class.
+            5) Grab a pointer for the current class to the current implementation of `resume`.
+            6) Grab a pointer for the super class to the current implementation of `resume`.
+            7) If the current class implementation of `resume` is not equal to the super class implementation of `resume` AND the current implementation of `resume` is not equal to the original implementation of `af_resume`, THEN swizzle the methods
+            8) Set the current class to the super class, and repeat steps 3-8

+
+AFNetworking is a delightful networking library for iOS, macOS, watchOS, and tvOS. It's built on top of the [Foundation URL Loading System](https://developer.apple.com/documentation/foundation/url_loading_system), extending the powerful high-level networking abstractions built into Cocoa. It has a modular architecture with well-designed, feature-rich APIs that are a joy to use.
+
+Perhaps the most important feature of all, however, is the amazing community of developers who use and contribute to AFNetworking every day. AFNetworking powers some of the most popular and critically-acclaimed apps on the iPhone, iPad, and Mac.
+

+
+## Installation
+AFNetworking supports multiple methods for installing the library in a project.
+
+## Installation with CocoaPods
+
+To integrate AFNetworking into your Xcode project using CocoaPods, specify it in your `Podfile`:
+
+```ruby
+pod 'AFNetworking', '~> 4.0'
+```
+
+### Installation with Swift Package Manager
+
+Once you have your Swift package set up, adding AFNetworking as a dependency is as easy as adding it to the `dependencies` value of your `Package.swift`.
+
+```swift
+dependencies: [
+    .package(url: "https://github.com/AFNetworking/AFNetworking.git", .upToNextMajor(from: "4.0.0"))
+]
+```
+
+> Note: AFNetworking's Swift package does not include it's UIKit extensions.
+
+### Installation with Carthage
+
+[Carthage](https://github.com/Carthage/Carthage) is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks. To integrate AFNetworking, add the following to your `Cartfile`.
+
+```ogdl
+github "AFNetworking/AFNetworking" ~> 4.0
+```

+- `AFNetworkReachabilityManager`
+
+## Usage
+
+### AFURLSessionManager
+
+`AFURLSessionManager` creates and manages an `NSURLSession` object based on a specified `NSURLSessionConfiguration` object, which conforms to `<NSURLSessionTaskDelegate>`, `<NSURLSessionDataDelegate>`, `<NSURLSessionDownloadDelegate>`, and `<NSURLSessionDelegate>`.
+
+#### Creating a Download Task
+
+```objective-c
+NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
+AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];
+
+NSURL *URL = [NSURL URLWithString:@"http://example.com/download.zip"];
+NSURLRequest *request = [NSURLRequest requestWithURL:URL];
+
+NSURLSessionDownloadTask *downloadTask = [manager downloadTaskWithRequest:request progress:nil destination:^NSURL *(NSURL *targetPath, NSURLResponse *response) {
+    NSURL *documentsDirectoryURL = [[NSFileManager defaultManager] URLForDirectory:NSDocumentDirectory inDomain:NSUserDomainMask appropriateForURL:nil create:NO error:nil];
+    return [documentsDirectoryURL URLByAppendingPathComponent:[response suggestedFilename]];
+} completionHandler:^(NSURLResponse *response, NSURL *filePath, NSError *error) {
+    NSLog(@"File downloaded to: %@", filePath);
+}];
+[downloadTask resume];
+```
+
+#### Creating an Upload Task
+
+```objective-c
+NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
+AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];
+
+NSURL *URL = [NSURL URLWithString:@"http://example.com/upload"];
+NSURLRequest *request = [NSURLRequest requestWithURL:URL];
+
+NSURL *filePath = [NSURL fileURLWithPath:@"file://path/to/image.png"];
+NSURLSessionUploadTask *uploadTask = [manager uploadTaskWithRequest:request fromFile:filePath progress:nil completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {
+    if (error) {
+        NSLog(@"Error: %@", error);
+    } else {
+        NSLog(@"Success: %@ %@", response, responseObject);
+    }
+}];
+[uploadTask resume];
+```
+
+#### Creating an Upload Task for a Multi-Part Request, with Progress
+
+```objective-c
+NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:@"http://example.com/upload" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
+        [formData appendPartWithFileURL:[NSURL fileURLWithPath:@"file://path/to/image.jpg"] name:@"file" fileName:@"filename.jpg" mimeType:@"image/jpeg" error:nil];
+    } error:nil];
+
+AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
+
+NSURLSessionUploadTask *uploadTask;
+uploadTask = [manager
+              uploadTaskWithStreamedRequest:request
+              progress:^(NSProgress * _Nonnull uploadProgress) {
+                  // This is not called back on the main queue.
+                  // You are responsible for dispatching to the main queue for UI updates
+                  dispatch_async(dispatch_get_main_queue(), ^{
+                      //Update the progress view
+                      [progressView setProgress:uploadProgress.fractionCompleted];
+                  });
+              }
+              completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) {
+                  if (error) {
+                      NSLog(@"Error: %@", error);
+                  } else {
+                      NSLog(@"%@ %@", response, responseObject);
+                  }
+              }];
+
+[uploadTask resume];
+```
+
+#### Creating a Data Task
+
+```objective-c
+NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
+AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];
+
+NSURL *URL = [NSURL URLWithString:@"http://httpbin.org/get"];
+NSURLRequest *request = [NSURLRequest requestWithURL:URL];
+
+NSURLSessionDataTask *dataTask = [manager dataTaskWithRequest:request completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {
+    if (error) {
+        NSLog(@"Error: %@", error);
+    } else {
+        NSLog(@"%@ %@", response, responseObject);
+    }
+}];
+[dataTask resume];
+```
+
+---
+
+### Request Serialization
+
+Request serializers create requests from URL strings, encoding parameters as either a query string or HTTP body.
+
+```objective-c
+NSString *URLString = @"http://example.com";
+NSDictionary *parameters = @{@"foo": @"bar", @"baz": @[@1, @2, @3]};
+```
+
+#### Query String Parameter Encoding
+
+```objective-c
+[[AFHTTPRequestSerializer serializer] requestWithMethod:@"GET" URLString:URLString parameters:parameters error:nil];
+```
+
+    GET http://example.com?foo=bar&baz[]=1&baz[]=2&baz[]=3
+
+#### URL Form Parameter Encoding
+
+```objective-c
+[[AFHTTPRequestSerializer serializer] requestWithMethod:@"POST" URLString:URLString parameters:parameters error:nil];
+```
+
+    POST http://example.com/
+    Content-Type: application/x-www-form-urlencoded
+
+    foo=bar&baz[]=1&baz[]=2&baz[]=3
+
+#### JSON Parameter Encoding
+
+```objective-c
+[[AFJSONRequestSerializer serializer] requestWithMethod:@"POST" URLString:URLString parameters:parameters error:nil];
+```
+
+    POST http://example.com/
+    Content-Type: application/json
+
+    {"foo": "bar", "baz": [1,2,3]}
+
+---
+
+### Network Reachability Manager
+
+`AFNetworkReachabilityManager` monitors the reachability of domains, and addresses for both WWAN and WiFi network interfaces.
+
+* Do not use Reachability to determine if the original request should be sent.
+	* You should try to send it.
+* You can use Reachability to determine when a request should be automatically retried.
+	* Although it may still fail, a Reachability notification that the connectivity is available is a good time to retry something.
+* Network reachability is a useful tool for determining why a request might have failed.
+	* After a network request has failed, telling the user they're offline is better than giving them a more technical but accurate error, such as "request timed out."
+
+See also [WWDC 2012 session 706, "Networking Best Practices."](https://developer.apple.com/videos/play/wwdc2012-706/).
+
+#### Shared Network Reachability
+
+```objective-c
+[[AFNetworkReachabilityManager sharedManager] setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
+    NSLog(@"Reachability: %@", AFStringFromNetworkReachabilityStatus(status));
+}];
+
+[[AFNetworkReachabilityManager sharedManager] startMonitoring];
+```
+
+---
+
+### Security Policy
+
+`AFSecurityPolicy` evaluates server trust against pinned X.509 certificates and public keys over secure connections.
+
+Adding pinned SSL certificates to your app helps prevent man-in-the-middle attacks and other vulnerabilities. Applications dealing with sensitive customer data or financial information are strongly encouraged to route all communication over an HTTPS connection with SSL pinning configured and enabled.
+
+#### Allowing Invalid SSL Certificates
+
+```objective-c
+AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
+manager.securityPolicy.allowInvalidCertificates = YES; // not recommended for production
+```
+
+---

+
+> If you want to implement night mode in Swift project without import Objective-C code. This is the Swift version [NightNight](https://github.com/Draveness/NightNight)
+
+# How To Get Started
+
+DKNightVersion supports multiple methods for installing the library in a project.
+
+## Installation with CocoaPods
+
+[CocoaPods](https://cocoapods.org/) is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries like DKNightVersion in your projects. See the [Get Started section](https://cocoapods.org/#get_started) for more details.
+
+### Podfile
+
+To integrate DKNightVersion into your Xcode project using CocoaPods, specify it in your `Podfile`:
+
+```shell
+pod "DKNightVersion"
+```
+
+Then, run the following command:
+
+```shell
+$ pod install
+```
+
+
+### Import
+
+Import DKNightVersion header file
+
+```objectivec
+#import <DKNightVersion/DKNightVersion.h>
+```
+
+## Usage
+
+Checkout `DKColorTable.txt` file in your project, which locates in `Pods/DKNightVersion/Resources/DKNightVersion.txt`.
+```
+NORMAL   NIGHT
+#ffffff  #343434 BG
+#aaaaaa  #313131 SEP
+```
+
+> You can also create another color table file, and specify it with [DKColorTable](#dkcolortable).
+
+And then, set color picker like this with `DKColorPickerWithKey`, which generates a DKColorPicker block
+
+```objectivec
+self.view.dk_backgroundColorPicker = DKColorPickerWithKey(BG);
+```
+
+After the current theme version change to `DKThemeVersionNight`, the view background color will switch to `#343434`.
+
+```objectivec
+[DKNightVersionManager nightFalling];
+``` 
+
+or change theme version by manager's property `themeVersion` which is a string
+
+```objectivec
+DKNightVersionManager *manager = [DKNightVersionManager sharedInstance];
+manager.themeVersion = DKThemeVersionNormal;
+```
+
+## Advanced Usage
+
+There are two approaches you can use to integrate night mode to your iOS App.
+
+### DKNightVersionManager
+
+The latest version for DKNightVersion add a readonly `dk_manager` property for `NSObject` returns the `DKNightVersionManager` singleton.
+
+#### Change Theme
+
+You can call `nightFalling` or `dawnComing` to switch current theme version to `DKThemeVersionNight` or `DKThemeVersionNormal`.
+
+```objectivec
+[self.dk_manager dawnComing];
+[self.dk_manager nightFalling];
+```
+
+Modify `themeVersion` property to directly switch theme version.
+
+```objectivec
+self.dk_manager.themeVersion = DKThemeVersionNormal;
+self.dk_manager.themeVersion = DKThemeVersionNight;
+// if there is a RED column in DKColorTable.txt (default) or in 
+// other `file` if you customize `file` property for `DKColorTable`
+self.dk_manager.themeVersion = @"RED"; 
+```
+
+#### Post Notification
+
+Every time the current theme version changes, `DKNightVersionManager` will post a `DKNightVersionThemeChangingNotification`. If you wanna to do some customization, you can observe this notification and react with proper actions.
+
+### DKColorPicker
+
+`DKColorPicker` is the core of DKNightVersion. And this lib adds dk_colorPicker to every UIKit and Core Animation components. Ex:
+
+```objectivec
+@property (nonatomic, copy, setter = dk_setBackgroundColorPicker:) DKColorPicker dk_backgroundColorPicker;
+@property (nonatomic, copy, setter = dk_setTintColorPicker:) DKColorPicker dk_tintColorPicker;
+```
+
+DKColorPicker is defined in `DKColor.h` file receives a `DKThemeVersion` as the parameter and returns a `UIColor`.
+
+```objectivec
+typedef UIColor *(^DKColorPicker)(DKThemeVersion *themeVersion);
+```
+
++ Use `DKColorPickerWithKey(key)` to obtain `DKColorPicker` from `DKColorTable`
+
+    ```objectivec
+    view.dk_backgroundColorPicker = DKColorPickerWithKey(BG);
+    ```
+
++ Use `DKColorPickerWithRGB` to generate a `DKColorPicker`
+
+    ```objectivec
+    view.dk_backgroundColorPicker =  DKColorPickerWithRGB(0xffffff, 0x343434);
+    ```
+
+### DKColorTable
+
+`DKColorTable` is a new feature in DKNightVersion which providing us an elegant way to manage color setting in a project. Use as follows:
+
+There is a file called `DKColorTable.txt`
+
+```
+NORMAL   NIGHT
+#ffffff  #343434 BG
+#aaaaaa  #313131 SEP
+```
+
+The first line of this file indicated different themes. **NORMAL is required column**, and others are optional. So if you don't need to integrate different themes in your app, just leave the first column in this file, like this:
+
+```
+NORMAL
+#ffffff BG
+#aaaaaa SEP
+```
+
+`NORMAL` and `NIGHT` are two different themes, `NORMAL` is the default and for normal mode. `NIGHT` is optional and for night mode.
+
+You can add multiple columns in this `DKColorTable.txt` file as many as you want.
+
+```
+NORMAL   NIGHT    RED
+#ffffff  #343434  #ff0000 BG
+#aaaaaa  #313131  #ff0000 SEP
+```
+
+The last column is the key for a color entry, DKNightVersion uses the current `themeVersion` (ex: `NORMAL` `NIGHT` and `RED`) and key (ex: `BG`, `SEP`) to find the corresponding color in DKColorTable.
+
+`DKColorTable` has a property `file`, it will loads the color setting in this `file` when `+ [DKColorTable sharedColorTable` is called. Default value of `file` is `DKColorTable.txt`.
+
+```objectivec
+@property (nonatomic, strong) NSString *file;
+```
+
+You can also add another file into your project and fill your color setting in that file.
+
+```
+// color.txt
+NORMAL   NIGHT
+#ffffff  #343434 BG
+```
+
+And change `file` value
+
+```objectivec
+[DKColorTable sharedColorTable].file = @"color.txt"
+```
+
+This will reload color setting from `color.txt` file.
+
+### Create temporary DKColorPicker
+
+If you'd want to create some temporary DKColorPicker, you can use these methods.
+
+```objectivec
+view.dk_backgroundColorPicker =  DKColorPickerWithRGB(0xffffff, 0x343434);
+```
+
+`DKColorPickerWithRGB` will return a DKColorPicker which set background color to `#ffffff` when current theme version is `DKThemeVersionNormal` and `#343434` when it is `DKThemeVersionNight`.
+
+There are also some similar functions like `DKColorPickerWithColors`
+
+```objectivec
+DKColorPicker DKColorPickerWithRGB(NSUInteger normal, ...);
+DKColorPicker DKColorPickerWithColors(UIColor *normalColor, ...);
+```
+
+`DKColor` also provides a cluster of convenient `API` which returns `DKColorPicker` block, these blocks **return the same color in different themes**.
+
+```objectivec
++ (DKColorPicker)colorPickerWithUIColor:(UIColor *)color;
+
++ (DKColorPicker)colorPickerWithWhite:(CGFloat)white alpha:(CGFloat)alpha;
++ (DKColorPicker)colorPickerWithHue:(CGFloat)hue saturation:(CGFloat)saturation brightness:(CGFloat)brightness alpha:(CGFloat)alpha;
++ (DKColorPicker)colorPickerWithRed:(CGFloat)red green:(CGFloat)green blue:(CGFloat)blue alpha:(CGFloat)alpha;
++ (DKColorPicker)colorPickerWithCGColor:(CGColorRef)cgColor;
++ (DKColorPicker)colorPickerWithPatternImage:(UIImage *)image;
+#if __has_include(<CoreImage/CoreImage.h>)
++ (DKColorPicker)colorPickerWithCIColor:(CIColor *)ciColor NS_AVAILABLE_IOS(5_0);
+#endif
+
++ (DKColorPicker)blackColor;
++ (DKColorPicker)darkGrayColor;
++ (DKColorPicker)lightGrayColor;
++ (DKColorPicker)whiteColor;
++ (DKColorPicker)grayColor;
++ (DKColorPicker)redColor;
++ (DKColorPicker)greenColor;
++ (DKColorPicker)blueColor;
++ (DKColorPicker)cyanColor;
++ (DKColorPicker)yellowColor;
++ (DKColorPicker)magentaColor;
++ (DKColorPicker)orangeColor;
++ (DKColorPicker)purpleColor;
++ (DKColorPicker)brownColor;
++ (DKColorPicker)clearColor;
+```
+
+### pickerify
+
+DKNightVersion provides an extremely powerful feature which can generate dk_xxxColorPicker with a macro called `pickerify`.
+
+```objectivec
+@pickerify(TableViewCell, cellTintColor)
+```
+
+This will automatically generate `dk_cellTintColorPicker` for you.
+
+
+### DKImagePicker
+
+Use `DKImagePicker` to change images when `manager.themeVersion` changes.
+
+```objectivec
+imageView.dk_imagePicker = DKImagePickerWithNames(@"normal", @"night");
+```
+
+The first image is used for `NORMAL` theme the second is used for `NIGHT` theme, cuz themes order in 
+DKColorTable.txt file is NORMAL NIGHT.
+
+If your file like this:
+
+```
+NORMAL   NIGHT    RED
+#ffffff  #343434  #fafafa BG
+#aaaaaa  #313131  #aaaaaa SEP
+#0000ff  #ffffff  #fa0000 TINT
+#000000  #ffffff  #000000 TEXT
+#ffffff  #444444  #ffffff BAR
+```
+
+Set your image picker in this order:
+
+```objectivec
+imageView.dk_imagePicker = DKImagePickerWithNames(@"normal", @"night", @"red");
+```
+
+The order of images or names is exactly the same in DKColorTable.txt file.
+
+```objectivec
+DKImagePicker DKImagePickerWithImages(UIImage *normalImage, ...);
+DKImagePicker DKImagePickerWithNames(NSString *normalName, ...);
+```

+
+## What
+
+YTKNetwork is a high level request util based on [AFNetworking][AFNetworking]. It's developed by the iOS Team of YuanTiKu. It provides a High Level API for network request.
+
+YTKNetwork is used in all products of YuanTiKu, including: [YuanTiKu][YuanTiKu], [YuanSoTi][YuanSoTi], [YuanFuDao][YuanFuDao], [FenBiZhiBoKe][FenBiZhiBoKe].
+
+[**中文说明**](Docs/README_cn.md)
+
+## Features
+
+* Response can be cached by expiration time
+* Response can be cached by version number
+* Set common base URL and CDN URL
+* Validate JSON response
+* Resume download
+* `block` and `delegate` callback
+* Batch requests (see `YTKBatchRequest`)
+* Chain requests (see `YTKChainRequest`)
+* URL filter, replace part of URL, or append common parameter 
+* Plugin mechanism, handle request start and finish. A plugin for show "Loading" HUD is provided
+
+## Who
+
+YTKNetowrk is suitable for a slightly more complex project, not for a simple personal project.
+
+YTKNetwork is helpful if you want to cache requests, manage the dependences of requests, or validate the JSON response. And if you want to cache requests based on request version, this is one of the greatest advantages of YTKNetwork.
+
+## Why 
+
+YTKNetwork provides YTKRequest to handle every network request. You should inherit it and override some methods to define custom requests in your project.
+
+The main idea is use the Command Pattern. The benefits are:
+
+ * Your code is decoupled to detail network request framework, it's easy to replace it. Actually, YTKNetwork is originally based on ASIHttpRequest, we just spent two days to switch to AFNetworking.
+ * Handle common logic in base class.
+ * Easier Persistence
+
+But YTKNetwork is not suitable if your project is very simple. You can use AFNetworking directly in controller.
+
+## Installation
+
+To use YTKNetwork add the following to your Podfile
+
+    pod 'YTKNetwork'
+
+Or add this in your Cartfile:
+
+    github "yuantiku/YTKNetwork" ~> 3.0
+
+## Requirements
+
+| YTKNetwork Version | AFNetworking Version |  Minimum iOS Target | Note |
+|:------------------:|:--------------------:|:-------------------:|:-----|
+| 3.x | 4.x | iOS 9 | Xcode 11+ is required. |
+| 2.x | 3.x | iOS 7 | Xcode 7+ is required. |
+| 1.x | 2.x | iOS 6 | n/a |
+
+YTKNetwork is based on AFNetworking. You can find more detail about version compatibility at [AFNetworking README](https://github.com/AFNetworking/AFNetworking).
