此文章是基于AFNetworking2.5版本的，需要看AFNetworking2.0版本的请看上一篇文章：AFNetworking2.0使用

1.检测网络状态

+ (void)netWorkStatus{    /**     AFNetworkReachabilityStatusUnknown          = -1,  // 未知     AFNetworkReachabilityStatusNotReachable     = 0,   // 无连接     AFNetworkReachabilityStatusReachableViaWWAN = 1,   // 3G 花钱     AFNetworkReachabilityStatusReachableViaWiFi = 2,   // WiFi     */    // 如果要检测网络状态的变化,必须用检测管理器的单例的startMonitoring    [[AFNetworkReachabilityManager sharedManager] startMonitoring];        // 检测网络连接的单例,网络变化时的回调方法    [[AFNetworkReachabilityManager sharedManager] setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {        NSLog(@"%ld", status);    }];}

2.JSON方式获取数据

+ (void)JSONDataWithUrl:(NSString *)url success:(void (^)(id json))success fail:(void (^)())fail;{    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];        NSDictionary *dict = @{@"format": @"json"};    // 网络访问是异步的,回调是主线程的,因此程序员不用管在主线程更新UI的事情    [manager GET:url parameters:dict success:^(AFHTTPRequestOperation *operation, id responseObject) {        if (success) {            success(responseObject);        }    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {        NSLog(@"%@", error);        if (fail) {            fail();        }    }];}

3.xml方式获取数据

+ (void)XMLDataWithUrl:(NSString *)urlStr success:(void (^)(id xml))success fail:(void (^)())fail{    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];        // 返回的数据格式是XML    manager.responseSerializer = [AFXMLParserResponseSerializer serializer];        NSDictionary *dict = @{@"format": @"xml"};        // 网络访问是异步的,回调是主线程的,因此程序员不用管在主线程更新UI的事情    [manager GET:urlStr parameters:dict success:^(AFHTTPRequestOperation *operation, id responseObject) {        if (success) {            success(responseObject);        }            } failure:^(AFHTTPRequestOperation *operation, NSError *error) {        NSLog(@"%@", error);        if (fail) {            fail();        }    }];}

4.post提交json数据

+ (void)postJSONWithUrl:(NSString *)urlStr parameters:(id)parameters success:(void (^)(id responseObject))success fail:(void (^)())fail{    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];    // 设置请求格式    manager.requestSerializer = [AFJSONRequestSerializer serializer];    // 设置返回格式    manager.responseSerializer = [AFHTTPResponseSerializer serializer];    [manager POST:urlStr parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {//        NSString *result = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];        if (success) {            success(responseObject);        }    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {        NSLog(@"%@", error);        if (fail) {            fail();        }    }];    }

5.下载文件

+ (void)sessionDownloadWithUrl:(NSString *)urlStr success:(void (^)(NSURL *fileURL))success fail:(void (^)())fail{    NSURLSessionConfiguration *config = [NSURLSessionConfiguration defaultSessionConfiguration];    AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:config];    NSString *urlString = [urlStr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];        NSURL *url = [NSURL URLWithString:urlString];    NSURLRequest *request = [NSURLRequest requestWithURL:url];        NSURLSessionDownloadTask *task = [manager downloadTaskWithRequest:request progress:nil destination:^NSURL *(NSURL *targetPath, NSURLResponse *response) {        // 指定下载文件保存的路径        //        NSLog(@"%@ %@", targetPath, response.suggestedFilename);        // 将下载文件保存在缓存路径中        NSString *cacheDir = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES)[0];        NSString *path = [cacheDir stringByAppendingPathComponent:response.suggestedFilename];                // URLWithString返回的是网络的URL,如果使用本地URL,需要注意//        NSURL *fileURL1 = [NSURL URLWithString:path];        NSURL *fileURL = [NSURL fileURLWithPath:path];        //        NSLog(@"== %@ |||| %@", fileURL1, fileURL);        if (success) {            success(fileURL);        }                return fileURL;    } completionHandler:^(NSURLResponse *response, NSURL *filePath, NSError *error) {        NSLog(@"%@ %@", filePath, error);        if (fail) {            fail();        }    }];        [task resume];}

6.文件上传－自定义上传文件名

+ (void)postUploadWithUrl:(NSString *)urlStr fileUrl:(NSURL *)fileURL fileName:(NSString *)fileName fileType:(NSString *)fileTye success:(void (^)(id responseObject))success fail:(void (^)())fail{    // 本地上传给服务器时,没有确定的URL,不好用MD5的方式处理    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];    manager.responseSerializer = [AFHTTPResponseSerializer serializer];    //@"http://localhost/demo/upload.php"    [manager POST:urlStr parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {        //        NSURL *fileURL = [[NSBundle mainBundle] URLForResource:@"头像1.png" withExtension:nil];                // 要上传保存在服务器中的名称        // 使用时间来作为文件名 2014-04-30 14:20:57.png        // 让不同的用户信息,保存在不同目录中//        NSDateFormatter *formatter = [[NSDateFormatter alloc] init];//        // 设置日期格式//        formatter.dateFormat = @"yyyy-MM-dd HH:mm:ss";//        NSString *fileName = [formatter stringFromDate:[NSDate date]];                //@"image/png"        [formData appendPartWithFileURL:fileURL name:@"uploadFile" fileName:fileName mimeType:fileTye error:NULL];            } success:^(AFHTTPRequestOperation *operation, id responseObject) {        if (success) {            success(responseObject);        }    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {        if (fail) {            fail();        }    }];}

7.文件上传－随机生成文件名

+ (void)postUploadWithUrl:(NSString *)urlStr fileUrl:(NSURL *)fileURL success:(void (^)(id responseObject))success fail:(void (^)())fail{    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];    // AFHTTPResponseSerializer就是正常的HTTP请求响应结果:NSData    // 当请求的返回数据不是JSON,XML,PList,UIImage之外,使用AFHTTPResponseSerializer    // 例如返回一个html,text...    //    // 实际上就是AFN没有对响应数据做任何处理的情况    manager.responseSerializer = [AFHTTPResponseSerializer serializer];        // formData是遵守了AFMultipartFormData的对象    [manager POST:urlStr parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {                // 将本地的文件上传至服务器//        NSURL *fileURL = [[NSBundle mainBundle] URLForResource:@"头像1.png" withExtension:nil];                [formData appendPartWithFileURL:fileURL name:@"uploadFile" error:NULL];    } success:^(AFHTTPRequestOperation *operation, id responseObject) {//        NSString *result = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];//        //        NSLog(@"完成 %@", result);        if (success) {            success(responseObject);        }    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {        NSLog(@"错误 %@", error.localizedDescription);        if (fail) {            fail();        }    }];}
