How to get frame of image when using MKNetworkKit setImageFromURL?

Question

I am trying to get the size of an image after it is downloaded using setImageFromURL:

UIImageView *img = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];
[UIImageView setDefaultEngine:appDelegate.imageCache];
[img setImageFromURL:[NSURL URLWithString:@"http://testurl.com/testimg.jpg"]];
//img.frame = CGRectMake (0, 0, img.image.size.width, img.image.size.height);
[self.view addSubview:img];

I'm using MKNetworkKit -- is there a way to add a completion handler to the setImageFromURL method?

I was able to do it by adding this line:

 self.frame = CGRectMake(0, 0, fetchedImage.size.width, fetchedImage.size.height);

to UIImageView+MKNetworkKitAdditions.m:

if(imageCacheEngine) {
    self.imageFetchOperation = [imageCacheEngine imageAtURL:url
                   size:self.frame.size
      completionHandler:^(UIImage *fetchedImage, NSURL *url, BOOL isInCache) {

        self.frame = CGRectMake(0, 0, fetchedImage.size.width, fetchedImage.size.height);

        [UIView transitionWithView:self.superview
                          duration:isInCache?kFromCacheAnimationDuration:kFreshLoadAnimationDuration
                           options:UIViewAnimationOptionTransitionCrossDissolve | UIViewAnimationOptionAllowUserInteraction
                        animations:^{
                             self.image = fetchedImage;
                           } completion:nil];
          //[[NSNotificationCenter defaultCenter] postNotificationName:KW_IMAGE_LOADED object:nil];

      } errorHandler:^(MKNetworkOperation *completedOperation, NSError *error) {

        DLog(@"%@", error);
      }];
  } else {

    DLog(@"No default engine found and imageCacheEngine parameter is null")
  }
