我想问一下 AFNetworking 库是否在由于连接丢失而无法完成 http 操作的自动恢复时提供某种支持。

举个例子，我想排队更多的http post操作，每一个都用来上传一张图片：如何管理连接丢失的情况（我想知道是否有任何代码会重新启动未完成连接可用时操作）？

    NSURL *remoteUrl = [NSURL URLWithString:UPLOAD_SERVER_URL];
AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:remoteUrl];
[httpClient setParameterEncoding: AFJSONParameterEncoding];
[httpClient setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
    NSLog(@"Conenction lost...");
}];
NSMutableURLRequest *afRequest = [httpClient multipartFormRequestWithMethod:@"POST" 
                                                                       path:@"/upload/" 
                                                                 parameters:[photoBean asDictWithoutImageData]
                                                  constructingBodyWithBlock:^(id <AFMultipartFormData>formData) 
                                  {                                    
                                      [[photoBean asDict] enumerateKeysAndObjectsUsingBlock:^(NSString *key, id obj, BOOL *stop) {
                                          if ([key isEqualToString:@"media"])
                                          {
                                              [formData appendPartWithFileData: obj name:@"media" fileName:photoBean._imageFile mimeType:@"image/jpeg"];
                                          }

                                      }];

                                  }
                                  ];

AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:afRequest];
[operation setCompletionBlock:^{
    NSLog(@"%@", operation.responseString); //Gives a very scary warning
}];

[operation start];

谢谢！
