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. 12 | 13 | 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. 14 | 15 | ## How To Get Started 16 | 17 | - [Download AFNetworking](https://github.com/AFNetworking/AFNetworking/archive/master.zip) and try out the included Mac and iPhone example apps 18 | - Read the ["Getting Started" guide](https://github.com/AFNetworking/AFNetworking/wiki/Getting-Started-with-AFNetworking), [FAQ](https://github.com/AFNetworking/AFNetworking/wiki/AFNetworking-FAQ), or [other articles on the Wiki](https://github.com/AFNetworking/AFNetworking/wiki) 19 | 20 | ## Communication 21 | 22 | - If you **need help**, use [Stack Overflow](http://stackoverflow.com/questions/tagged/afnetworking). (Tag 'afnetworking') 23 | - If you'd like to **ask a general question**, use [Stack Overflow](http://stackoverflow.com/questions/tagged/afnetworking). 24 | - If you **found a bug**, _and can provide steps to reliably reproduce it_, open an issue. 25 | - If you **have a feature request**, open an issue. 26 | - If you **want to contribute**, submit a pull request. 27 | 28 | ## Installation 29 | AFNetworking supports multiple methods for installing the library in a project. 30 | 31 | ## Installation with CocoaPods 32 | 33 | To integrate AFNetworking into your Xcode project using CocoaPods, specify it in your `Podfile`: 34 | 35 | ```ruby 36 | pod 'AFNetworking', '~> 4.0' 37 | ``` 38 | 39 | ### Installation with Swift Package Manager 40 | 41 | 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`. 42 | 43 | ```swift 44 | dependencies: [ 45 | .package(url: "https://github.com/AFNetworking/AFNetworking.git", .upToNextMajor(from: "4.0.0")) 46 | ] 47 | ``` 48 | 49 | > Note: AFNetworking's Swift package does not include it's UIKit extensions. 50 | 51 | ### Installation with Carthage 52 | 53 | [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`. 54 | 55 | ```ogdl 56 | github "AFNetworking/AFNetworking" ~> 4.0 57 | ``` 58 | 59 | ## Requirements 60 | 61 | | AFNetworking Version | Minimum iOS Target | Minimum macOS Target | Minimum watchOS Target | Minimum tvOS Target | Notes | 62 | |:--------------------:|:---------------------------:|:----------------------------:|:----------------------------:|:----------------------------:|:-------------------------------------------------------------------------:| 63 | | 4.x | iOS 9 | macOS 10.10 | watchOS 2.0 | tvOS 9.0 | Xcode 11+ is required. | 64 | | 3.x | iOS 7 | OS X 10.9 | watchOS 2.0 | tvOS 9.0 | Xcode 7+ is required. `NSURLConnectionOperation` support has been removed. | 65 | | 2.6 -> 2.6.3 | iOS 7 | OS X 10.9 | watchOS 2.0 | n/a | Xcode 7+ is required. | 66 | | 2.0 -> 2.5.4 | iOS 6 | OS X 10.8 | n/a | n/a | Xcode 5+ is required. `NSURLSession` subspec requires iOS 7 or OS X 10.9. | 67 | | 1.x | iOS 5 | Mac OS X 10.7 | n/a | n/a | 68 | | 0.10.x | iOS 4 | Mac OS X 10.6 | n/a | n/a | 69 | 70 | (macOS projects must support [64-bit with modern Cocoa runtime](https://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/ObjCRuntimeGuide/Articles/ocrtVersionsPlatforms.html)). 71 | 72 | > Programming in Swift? Try [Alamofire](https://github.com/Alamofire/Alamofire) for a more conventional set of APIs. 73 | 74 | ## Architecture 75 | 76 | ### NSURLSession 77 | 78 | - `AFURLSessionManager` 79 | - `AFHTTPSessionManager` 80 | 81 | ### Serialization 82 | 83 | * `` 84 | - `AFHTTPRequestSerializer` 85 | - `AFJSONRequestSerializer` 86 | - `AFPropertyListRequestSerializer` 87 | * `` 88 | - `AFHTTPResponseSerializer` 89 | - `AFJSONResponseSerializer` 90 | - `AFXMLParserResponseSerializer` 91 | - `AFXMLDocumentResponseSerializer` _(macOS)_ 92 | - `AFPropertyListResponseSerializer` 93 | - `AFImageResponseSerializer` 94 | - `AFCompoundResponseSerializer` 95 | 96 | ### Additional Functionality 97 | 98 | - `AFSecurityPolicy` 99 | - `AFNetworkReachabilityManager` 100 | 101 | ## Usage 102 | 103 | ### AFURLSessionManager 104 | 105 | `AFURLSessionManager` creates and manages an `NSURLSession` object based on a specified `NSURLSessionConfiguration` object, which conforms to ``, ``, ``, and ``. 106 | 107 | #### Creating a Download Task 108 | 109 | ```objective-c 110 | NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration]; 111 | AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration]; 112 | 113 | NSURL *URL = [NSURL URLWithString:@"http://example.com/download.zip"]; 114 | NSURLRequest *request = [NSURLRequest requestWithURL:URL]; 115 | 116 | NSURLSessionDownloadTask *downloadTask = [manager downloadTaskWithRequest:request progress:nil destination:^NSURL *(NSURL *targetPath, NSURLResponse *response) { 117 | NSURL *documentsDirectoryURL = [[NSFileManager defaultManager] URLForDirectory:NSDocumentDirectory inDomain:NSUserDomainMask appropriateForURL:nil create:NO error:nil]; 118 | return [documentsDirectoryURL URLByAppendingPathComponent:[response suggestedFilename]]; 119 | } completionHandler:^(NSURLResponse *response, NSURL *filePath, NSError *error) { 120 | NSLog(@"File downloaded to: %@", filePath); 121 | }]; 122 | [downloadTask resume]; 123 | ``` 124 | 125 | #### Creating an Upload Task 126 | 127 | ```objective-c 128 | NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration]; 129 | AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration]; 130 | 131 | NSURL *URL = [NSURL URLWithString:@"http://example.com/upload"]; 132 | NSURLRequest *request = [NSURLRequest requestWithURL:URL]; 133 | 134 | NSURL *filePath = [NSURL fileURLWithPath:@"file://path/to/image.png"]; 135 | NSURLSessionUploadTask *uploadTask = [manager uploadTaskWithRequest:request fromFile:filePath progress:nil completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) { 136 | if (error) { 137 | NSLog(@"Error: %@", error); 138 | } else { 139 | NSLog(@"Success: %@ %@", response, responseObject); 140 | } 141 | }]; 142 | [uploadTask resume]; 143 | ``` 144 | 145 | #### Creating an Upload Task for a Multi-Part Request, with Progress 146 | 147 | ```objective-c 148 | NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:@"http://example.com/upload" parameters:nil constructingBodyWithBlock:^(id formData) { 149 | [formData appendPartWithFileURL:[NSURL fileURLWithPath:@"file://path/to/image.jpg"] name:@"file" fileName:@"filename.jpg" mimeType:@"image/jpeg" error:nil]; 150 | } error:nil]; 151 | 152 | AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]]; 153 | 154 | NSURLSessionUploadTask *uploadTask; 155 | uploadTask = [manager 156 | uploadTaskWithStreamedRequest:request 157 | progress:^(NSProgress * _Nonnull uploadProgress) { 158 | // This is not called back on the main queue. 159 | // You are responsible for dispatching to the main queue for UI updates 160 | dispatch_async(dispatch_get_main_queue(), ^{ 161 | //Update the progress view 162 | [progressView setProgress:uploadProgress.fractionCompleted]; 163 | }); 164 | } 165 | completionHandler:^(NSURLResponse * _Nonnull response, id _Nullable responseObject, NSError * _Nullable error) { 166 | if (error) { 167 | NSLog(@"Error: %@", error); 168 | } else { 169 | NSLog(@"%@ %@", response, responseObject); 170 | } 171 | }]; 172 | 173 | [uploadTask resume]; 174 | ``` 175 | 176 | #### Creating a Data Task 177 | 178 | ```objective-c 179 | NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration]; 180 | AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration]; 181 | 182 | NSURL *URL = [NSURL URLWithString:@"http://httpbin.org/get"]; 183 | NSURLRequest *request = [NSURLRequest requestWithURL:URL]; 184 | 185 | NSURLSessionDataTask *dataTask = [manager dataTaskWithRequest:request completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) { 186 | if (error) { 187 | NSLog(@"Error: %@", error); 188 | } else { 189 | NSLog(@"%@ %@", response, responseObject); 190 | } 191 | }]; 192 | [dataTask resume]; 193 | ``` 194 | 195 | --- 196 | 197 | ### Request Serialization 198 | 199 | Request serializers create requests from URL strings, encoding parameters as either a query string or HTTP body. 200 | 201 | ```objective-c 202 | NSString *URLString = @"http://example.com"; 203 | NSDictionary *parameters = @{@"foo": @"bar", @"baz": @[@1, @2, @3]}; 204 | ``` 205 | 206 | #### Query String Parameter Encoding 207 | 208 | ```objective-c 209 | [[AFHTTPRequestSerializer serializer] requestWithMethod:@"GET" URLString:URLString parameters:parameters error:nil]; 210 | ``` 211 | 212 | GET http://example.com?foo=bar&baz[]=1&baz[]=2&baz[]=3 213 | 214 | #### URL Form Parameter Encoding 215 | 216 | ```objective-c 217 | [[AFHTTPRequestSerializer serializer] requestWithMethod:@"POST" URLString:URLString parameters:parameters error:nil]; 218 | ``` 219 | 220 | POST http://example.com/ 221 | Content-Type: application/x-www-form-urlencoded 222 | 223 | foo=bar&baz[]=1&baz[]=2&baz[]=3 224 | 225 | #### JSON Parameter Encoding 226 | 227 | ```objective-c 228 | [[AFJSONRequestSerializer serializer] requestWithMethod:@"POST" URLString:URLString parameters:parameters error:nil]; 229 | ``` 230 | 231 | POST http://example.com/ 232 | Content-Type: application/json 233 | 234 | {"foo": "bar", "baz": [1,2,3]} 235 | 236 | --- 237 | 238 | ### Network Reachability Manager 239 | 240 | `AFNetworkReachabilityManager` monitors the reachability of domains, and addresses for both WWAN and WiFi network interfaces. 241 | 242 | * Do not use Reachability to determine if the original request should be sent. 243 | * You should try to send it. 244 | * You can use Reachability to determine when a request should be automatically retried. 245 | * Although it may still fail, a Reachability notification that the connectivity is available is a good time to retry something. 246 | * Network reachability is a useful tool for determining why a request might have failed. 247 | * 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." 248 | 249 | See also [WWDC 2012 session 706, "Networking Best Practices."](https://developer.apple.com/videos/play/wwdc2012-706/). 250 | 251 | #### Shared Network Reachability 252 | 253 | ```objective-c 254 | [[AFNetworkReachabilityManager sharedManager] setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) { 255 | NSLog(@"Reachability: %@", AFStringFromNetworkReachabilityStatus(status)); 256 | }]; 257 | 258 | [[AFNetworkReachabilityManager sharedManager] startMonitoring]; 259 | ``` 260 | 261 | --- 262 | 263 | ### Security Policy 264 | 265 | `AFSecurityPolicy` evaluates server trust against pinned X.509 certificates and public keys over secure connections. 266 | 267 | 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. 268 | 269 | #### Allowing Invalid SSL Certificates 270 | 271 | ```objective-c 272 | AFHTTPSessionManager *manager = [AFHTTPSessionManager manager]; 273 | manager.securityPolicy.allowInvalidCertificates = YES; // not recommended for production 274 | ``` 275 | 276 | --- 277 | 278 | ## Unit Tests 279 | 280 | AFNetworking includes a suite of unit tests within the Tests subdirectory. These tests can be run simply be executed the test action on the platform framework you would like to test. 281 | 282 | ## Credits 283 | 284 | AFNetworking is owned and maintained by the [Alamofire Software Foundation](http://alamofire.org). 285 | 286 | AFNetworking was originally created by [Scott Raymond](https://github.com/sco/) and [Mattt Thompson](https://github.com/mattt/) in the development of [Gowalla for iPhone](http://en.wikipedia.org/wiki/Gowalla). 287 | 288 | AFNetworking's logo was designed by [Alan Defibaugh](http://www.alandefibaugh.com/). 289 | 290 | And most of all, thanks to AFNetworking's [growing list of contributors](https://github.com/AFNetworking/AFNetworking/contributors). 291 | 292 | ### Security Disclosure 293 | 294 | If you believe you have identified a security vulnerability with AFNetworking, you should report it as soon as possible via email to security@alamofire.org. Please do not post it to a public issue tracker. 295 | 296 | ## License 297 | 298 | AFNetworking is released under the MIT license.

If you need to support animation, you can implement custom decoding (such as [YYImage](https://github.com/ibireme/YYImage)). 5 | 6 | ## Requirements 7 | 8 | - **iOS 9.0+** 9 | - **Xcode 11.0+** 10 | - **AFNetworking 4.0+** 11 | 12 | ## Usage 13 | 14 | ### Load image 15 | 16 | ```objective-c 17 | // UIImageView 18 | [imageView lc_setImageWithURL:[NSURL URLWithString:@"https://xxx"]]; 19 | 20 | // UIButton 21 | [button lc_setImageWithURL:[NSURL URLWithString:@"https://xxx"] forState:(UIControlStateNormal)]; 22 | ``` 23 | 24 | ### Custom decoding playback animation 25 | 26 | Use [YYImage](https://github.com/ibireme/YYImage) to implement custom decoding 27 | 28 | ```objective-c 29 | // custom 30 | [(LCAutoPurgingImageCache *)[LCWebImageManager defaultInstance].imageCache setCustomDecodedImage:^UIImage * _Nonnull(NSData * _Nonnull data, NSString * _Nonnull identifier) { 31 | return [[YYImage alloc] initWithData:data scale:UIScreen.mainScreen.scale]; 32 | }]; 33 | ``` 34 | 35 | Load image 36 | 37 | ```objective-c 38 | YYAnimatedImageView *imageView = [[YYAnimatedImageView alloc] init]; 39 | [imageView lc_setImageWithURL:[NSURL URLWithString:@"https://xxx"]]; 40 | ``` 41 | 42 | 43 | 44 | > Note: There is a display problem with YYImage above iOS 14. The source code of `YYAnimatedImageView` needs to be modified as follows: 45 | 46 | ```objective-c 47 | - (void)displayLayer:(CALayer *)layer { 48 | // modified code 49 | UIImage *currentFrame = _curFrame; 50 | if (currentFrame) { 51 | layer.contentsScale = currentFrame.scale; 52 | layer.contents = (__bridge id)currentFrame.CGImage; 53 | } else { 54 | // If we have no animation frames, call super implementation. iOS 14+ UIImageView use this delegate method for rendering. 55 | if ([UIImageView instancesRespondToSelector:@selector(displayLayer:)]) { 56 | [super displayLayer:layer]; 57 | } 58 | } 59 | 60 | // source code 61 | // if (_curFrame) { 62 | // layer.contents = (__bridge id)_curFrame.CGImage; 63 | // } 64 | } 65 | 66 | ``` 67 | 68 | ## Installation 69 | 70 | ### CocoaPods 71 | 72 | To integrate LCWebImage into your Xcode project using CocoaPods, specify it in your `Podfile`: 73 | 74 | ```ruby 75 | pod 'LCWebImage' 76 | ``` 77 | 78 | ### Manual 79 | 80 | 1. Download everything inside the LCWebImage folder; 81 | 2. Add (drag and drop) the source files in LCWebImage to your project; 82 | 3. Add `AFNetworking/NSURLSession` code. 83 | 84 | ## License 85 | 86 | LCWebImage is provided under the MIT license.
