@KSR Please add your code. Also, there are plenty of questions on SO for lazy loading of images in `UITableView`, search well before asking duplicate questions. — Amar, Sep 18 '13 at 09:01

Instead of Lazzy Loading I used following way in UItableView and its working for me without scrolling issue .

 dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_BACKGROUND, 0), ^(void) {

            NSData *imageData ;

            imageData = [UICommonUtils imageDataFromString:profile.Photo];

            dispatch_sync(dispatch_get_main_queue(), ^(void) {


                    if([imageData length] > 1)
                    {
                        //UIImageView* imageView = (UIImageView*)[cell viewWithTag:100];
                        cell.ProfileImage.image = [UIImage imageWithData:imageData];
                    }
                    else
                    {
                        cell.ProfileImage.image = [UIImage imageNamed:kDefaultProfileImage];
                    }

                });

            imageData = nil;
        });

Try it is your code, because without for loop its working,I didnt need to use for loop because my each table cell contain on only image at that time. – Divya Bhaloidiya Aug 29 '13 at 12:32
