只需要拷贝 AFNetworking UIKit+AFNetworking 这两个目录中的文件就可以正常使用
下面的类已从AFNetworking 3.0中废弃：
AFHTTPRequestOperationManager
AFHTTPSessionManager *manager = [AFHTTPSessionManagermanager]; progress :^( NSProgress * _Nonnull downloadProgress) success :^( NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) NSLog ( @" 这里打印请求成功要做的事 " ); NSHTTPURLResponse *HTTPResponse = ( NSHTTPURLResponse *)task. response ; NSDictionary *fields = [HTTPResponse allHeaderFields ]; // 原生 NSURLConnection 写法 NSLog ( @"fields = %@" , [fields description ]); NSArray *cookies = [ NSHTTPCookie cookiesWithResponseHeaderFields :fields forURL :[ NSURL URLWithString :url]]; for ( NSHTTPCookie *cookie in cookies) NSLog ( @"cookie1 － > %@" , cookie); NSString *cookieString = [[HTTPResponse allHeaderFields ] valueForKey : @"Set-Cookie" ]; NSLog ( @"cookie2 － > %@" , cookieString); NSHTTPCookieStorage *cookieJar = [ NSHTTPCookieStorage sharedHTTPCookieStorage ]; for ( NSHTTPCookie *cookie in [cookieJar cookies ]) NSLog ( @"cookie3 － > %@" , cookie); failure :^( NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) NSLog ( @"%@" ,error); // 这里打印错误信息 AFHTTPSessionManager *manager = [ AFHTTPSessionManager manager ]; NSMutableDictionary *parameters = @{ @"":@"", @"":@""}; progress:^(NSProgress * _Nonnull uploadProgress) success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) AFHTTPSessionManager *manager = [AFHTTPSessionManagermanager]; manage. requestSerializer = [ AFHTTPRequestSerializer serializer ]; manage.requestSerializer.stringEncoding = NSUTF8StringEncoding; manage. requestSerializer . timeoutInterval = 10 ; manage. responseSerializer = [ AFHTTPResponseSerializer serializer ]; manage. responseSerializer . stringEncoding = NSUTF8StringEncoding ; manage.responseSerializer.acceptableContentTypes = [NSSetsetWithObject:@"text/html"]; NSURL *url = [ NSURL URLWithString : @"" ]; NSURLRequest *request = [ NSURLRequest requestWithURL :url]; NSURLSessionDownloadTask *task = [manager downloadTaskWithRequest :request progress :^( NSProgress * _Nonnull downloadProgress) NSLog ( @"%lf" , 1.0 * downloadProgress. completedUnitCount / downloadProgress. totalUnitCount ); destination :^ NSURL * _Nonnull ( NSURL * _Nonnull targetPath, NSURLResponse * _Nonnull response) NSLog ( @" 默认下载地址 :%@" ,targetPath); // 设置下载路径，通过沙盒获取缓存地址，最后返回 NSURL 对象 NSString *filePath = [ NSSearchPathForDirectoriesInDomains ( NSCachesDirectory , NSUserDomainMask , YES ) lastObject ]; return [ NSURL URLWithString :filePath]; completionHandler :^( NSURLResponse * _Nonnull response, NSURL * _Nullable filePath, NSError * _Nullable error) NSLog ( @"%@--%@" ,response,filePath); AFHTTPSessionManager *manager = [ AFHTTPSessionManager manager ]; NSDictionary *dict = @{ @"" : @"" } ; NSString *urlString = @"" ; constructingBodyWithBlock :^( id < AFMultipartFormData > _Nonnull formData) UIImage *iamge = [ UIImage imageNamed : @"123.png" ]; NSData *data = UIImagePNGRepresentation (iamge); [formData appendPartWithFileData :data name : @"file" fileName : @"123.png" mimeType : @"image/png" ]; progress :^( NSProgress * _Nonnull uploadProgress) NSLog ( @"%lf" , 1.0 * uploadProgress. completedUnitCount / uploadProgress. totalUnitCount ); success :^( NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) NSLog ( @" 请求成功： %@" ,responseObject); failure :^( NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) NSLog ( @" 请求失败： %@" ,error); 第二种是通过URL来获取路径，进入沙盒或者系统相册等等

[[ AFNetworkReachabilityManager sharedManager ] startMonitoring ]; （2）在需要监测网络的地方调用该方法去获取当前网络状态
AFNetworkReachabilityManager *manager = [ AFNetworkReachabilityManager sharedManager ]; // 枚举里面四个状态 分别对应未知无网络数据 WiFi // typedef NS_ENUM(NSInteger, AFNetworkReachabilityStatus) { // AFNetworkReachabilityStatusUnknown = -1, 未知 // AFNetworkReachabilityStatusNotReachable = 0, 无网络 // AFNetworkReachabilityStatusReachableViaWWAN = 1, 蜂窝数据网络 // AFNetworkReachabilityStatusReachableViaWiFi = 2, WiFi [manager setReachabilityStatusChangeBlock :^( AFNetworkReachabilityStatus status) case AFNetworkReachabilityStatusUnknown : case AFNetworkReachabilityStatusNotReachable : case AFNetworkReachabilityStatusReachableViaWWAN : case AFNetworkReachabilityStatusReachableViaWiFi : NSLog ( @"WiFi 网络 " ); break ; default : 注：如果启动就去检测有可能得到的是 status == AFNetworkReachabilityStatusUnknown，建议延迟在调用或者 在收到监听网络状态回调以后再取 转载地址：http://gsgab.baihongyu.com/
