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

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
Nik
