Question

我正在使用AFNetworking，我正在使用图片上传功能。

它工作得很好。现在我将XCode更新为最新版本。 XCode 6.0.1。之后我更新了所有pods文件。但现在它没有用。我没有改变任何事情。

XCode 5.1和XCode 6.0.1这两个版本我正在使用AFNetworking 2.2.4。

我的代码是

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];

                NSString *boundary = @"---------------------------14737809831466499882746641449";
                NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];
                [request setValue:contentType               forHTTPHeaderField: @"Content-Type"];
                [request setValue:@"Keep-Alive"             forHTTPHeaderField:@"Connection"];
                [request setValue:@"multipart/form-data"    forHTTPHeaderField:@"ENCTYPE"];
                [request setValue:@"test"                   forHTTPHeaderField:@"uploaded_file"];

                NSError *error = nil;
                request = [self.requestSerializer multipartFormRequestWithMethod:@"POST"
                                                                       URLString:APIURL
                                                                      parameters:nil
                                                       constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
                                                           [formData appendPartWithFileData:horse.imageData
                                                                                       name:@"uploaded_file"
                                                                                   fileName:@"myimage.jpg"
                                                                                   mimeType:@"image/jpeg"];
                                                       }
                                                                           error:&error];


                AFHTTPRequestOperation *operation =
                [self HTTPRequestOperationWithRequest:request
                                              success:^(AFHTTPRequestOperation *operation, id responseObject) {



                                              } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
                                                  NSLog(@"Failure %@", error.description);
                                              }];

                [operation setUploadProgressBlock:^(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite) {
                    NSLog(@"Wrote %ld/%ld", (long)totalBytesWritten, (long)totalBytesExpectedToWrite);
                }];

                [operation start];

错误消息

我在这里使用旧的AFNetwoking。我将AFNetworking 2.2.4更改为2.4.1。然后它正在工作。无论如何，谢谢@ n00bProgrammer
