MKNetworkEngine and UIImageView

gistfile1.m

[AppDelegate.imageFetcher imageAtURL:self.profile.avatarURL
                            onCompletion:^(UIImage *image, NSURL *url, BOOL isInCache)
     {
         // this "if" is to prevent images flashing repeatedly when cells are reused.
         if ([[self.profile.avatarURL absoluteString] isEqualToString:[url absoluteString]]) {

                 self.avatarImageView.image = resizedImage;
         }
     }];

thanks for the quick reply Mugunth.
I'm testing this with a twitter stream and using this:

if ([[[tweet objectForKey:@"user"] objectForKey:@"profile_image_url"] isEqualToString:[fetchedURL absoluteString]]) { cell.imageView.image = fetchedImage; }

how should I best maintain a reference to the originally requested URL when scrolling and the subsequent delay in the request?
the newly loadd images still 'cycle'

many thanks once again
Nik

I didn't quite understand your question. Maintain a reference to what? Mugunth Author | Developer | Trainer iOS 5 Programming book iBooks: http://mk.sg/ibook Amazon: http://mk.sg/ios5book

Hi Mugunth, apologies if I'm unclear. Basically the tableview image is not refreshed until the tableview reloads.

    [ApplicationDelegate.engine imageAtURL:[NSURL URLWithString:[[tweet objectForKey:@"user"] objectForKey:@"profile_image_url"]] onCompletion:^(UIImage *fetchedImage, NSURL *fetchedURL, BOOL isInCache) {
        if(isInCache){
            cell.imageView.image = fetchedImage;

        }else if ([[[tweet objectForKey:@"user"] objectForKey:@"profile_image_url"] isEqualToString:[fetchedURL absoluteString]]) {
            cell.imageView.image = fetchedImage;
        }else{
            cell.imageView.image = nil;


        }
    }];

There is likely a very simple solution which I'm missing, but any assistance in understanding how I can check the MKNetworkKit cache before starting the block request and thereby having the image show immediately would be greatly appreciated.

Previously I would maintain a dictionary of cached images in my app Delegate and either show if the URL was already available in the cache or start an NSOperation to grab it.

cheers
