AFNetworking不打成功和錯誤

Question

我想上傳一個PNG圖像和一些PARAMS我軌服務器和 我遵循http://nsscreencast.com/episodes/31-posting-multi-part-forms-with-afnetworking

這個例子，我的代碼片斷如下

代碼運行時，我看到進展從0到95..98％（它看起來並不是完成了）..它從來沒有擊中我的軌道控制器。它會凍結我的iOS應用程序......任何想法爲什麼它會凍結我的應用程序？我究竟做錯了什麼？謝謝，任何意見或意見，歡迎/讚賞。

NSData *imageData = UIImagePNGRepresentation(image); 

NSDictionary *params = @{ 
         @"latte[location]" : @"value1", 
         @"latte[submitted_by]" : @"value2", 
         @"latte[comments]" : @"value3" 
         }; 

NSURLRequest *putRequest = [[MApiClient sharedInstance] multipartFormRequestWithMethod:@"PUT" 
                        path:@"somepath.json" 
                      parameters:params 
                  constructingBodyWithBlock:^(id formData) { 
                   [formData appendPartWithFileData:imageData 
                          name:@"latte[photo]" 
                         fileName:@"latte.png" 
                         mimeType:@"image/png"]; 
                  }]; 

AFHTTPRequestOperation *operation = [[AFJSONRequestOperation alloc] initWithRequest:putRequest]; 
[operation setUploadProgressBlock:^(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite) { 
    NSLog(@"%f", (totalBytesWritten/(float) totalBytesExpectedToWrite)); 

}]; 



[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) { 
    if (operation.response.statusCode == 200 || operation.response.statusCode == 201) { 
     NSLog(@"whats here, %@", responseObject); 
    } else { 
     NSLog(@"whats here, %@", responseObject); 
    } 
} failure:^(AFHTTPRequestOperation *operation, NSError *error) { 
    NSLog(@"whats here, %@", error); 

}]; 

[[MyApiClient sharedInstance] enqueueHTTPRequestOperation:operation];

我會分析你的項目，它可能會拋出一些塊變量的問題。
