AFNetworking UIImageView setImageWithURLRequest returning response code 0

I am using AFNetworking's UIImageView category and I am constantly getting a response code of 0 in my response code status. Any idea why this is? Here's how I am doing it:

[self.newsPicture_ setImageWithURLRequest:storyImageRequest 
                                         placeholderImage:nil 
                                                  success:^(NSURLRequest * request, NSHTTPURLResponse * response, UIImage * image) {
                                                      if ([response statusCode] == 200){
                                                          dispatch_async(dispatch_get_main_queue(), ^(void){

 });
                                                      } else {
                                                          NSLog(@"RESPONSE ERROR WITH CODE IS %d", [response statusCode]);
                                                      }
                                                  }failure:^(NSURLRequest * request, NSHTTPURLResponse * response, NSError * error){
                                                      if (error){
                                                          NSLog(@"Error in requesting news story image");
                                                      }
                                                  }];

Any idea why this might be happening?

This is only happening when I am using the block based function call.

When I use setImageWithURL, everything works fine

UIImageView+AFNetworking uses an internal cache to optimize performance in scroll views and table views. A response code of 0 means that the image came out of that internal cache without making an HTTP request. You shouldn't need to check the status code being 200 in success, as that's already what the success/failure distinction is doing.
