Asynchronous image downloading with dispatch_async queue

Hi,

There's no need to implement any framework for LazyImage loading as of now. You can do it simply by writing few lines of code below.. Just take a look..


Example : 

UIActivityIndicatorView *activity = [[UIActivityIndicatorView alloc]init];
UIImageView * userImage = [[UIImageView alloc]init];

        [activity startAnimating];

        dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0ul);

        dispatch_async(queue, ^(void) {

            //  You may want to cache this explicitly instead of reloading every time.

            NSData *imageData = [NSData dataWithContentsOfURL:[NSURL URLWithString:url]];

            UIImage* image = [[UIImage alloc] initWithData:imageData];

            dispatch_async(dispatch_get_main_queue(), ^{

                // Capture the indexPath variable, not the cell variable, and use that

               userImage.image = image;

                [activity stopAnimating];

            });

       });
