设置AFNetworking网络请求的超时时间

也许大家使用的时候已经察觉到，设置AFNetworking的超时时间并不管用，但可以用特殊的方式来处理。

以下是笔者基于AFNetworking2.5.0封装的GET，POST请求用方法。

POST请求

+ (AFHTTPRequestOperation *)GETMethod:(NSString *)URLString                           parameters:(id)parameters                              success:(void (^)(AFHTTPRequestOperation *operation, id responseObject))success                              failure:(void (^)(AFHTTPRequestOperation *operation, NSError *error))failure {        AFHTTPRequestOperationManager *manager    = [AFHTTPRequestOperationManager manager];    // 设置超时时间    [manager.requestSerializer willChangeValueForKey:@"timeoutInterval"];    manager.requestSerializer.timeoutInterval = 10.f;    [manager.requestSerializer didChangeValueForKey:@"timeoutInterval"];        AFHTTPRequestOperation *httpOperation = [manager GET:URLString                                              parameters:parameters                                                 success:^(AFHTTPRequestOperation *operation, id responseObject) {                                                     if (success) {                                                         success(operation, responseObject);                                                     }                                                 }                                                 failure:^(AFHTTPRequestOperation *operation, NSError *error) {                                                     if (failure) {                                                         failure(operation, error);                                                     }                                                 }];        return httpOperation;}

+ (AFHTTPRequestOperation *)POSTMethod:(NSString *)URLString                            parameters:(id)parameters                               success:(void (^)(AFHTTPRequestOperation *operation, id responseObject))success                               failure:(void (^)(AFHTTPRequestOperation *operation, NSError *error))failure {        AFHTTPRequestOperationManager *manager            = [AFHTTPRequestOperationManager manager];    manager.requestSerializer                         = [AFJSONRequestSerializer serializer];    manager.responseSerializer.acceptableContentTypes = [manager.responseSerializer.acceptableContentTypes setByAddingObject:@"text/html"];            // 设置超时时间    [manager.requestSerializer willChangeValueForKey:@"timeoutInterval"];    manager.requestSerializer.timeoutInterval = 10.f;    [manager.requestSerializer didChangeValueForKey:@"timeoutInterval"];            AFHTTPRequestOperation *httpOperation = [manager POST:URLString                                               parameters:parameters                                                  success:^(AFHTTPRequestOperation *operation, id responseObject) {                                                      if (success) {                                                          success(operation, responseObject);                                                      }                                                  }                                                  failure:^(AFHTTPRequestOperation *operation, NSError *error) {                                                      if (failure) {                                                          failure(operation, error);                                                      }                                                  }];        return httpOperation;}

其中，设置这么一句话即可：
