This is what exactly i wanted.

[imgQuestionContainer sd_setImageWithURL:[NSURL URLWithString:[[arrOfLoadedPuzzel objectAtIndex:0] objectForKey:@"puzzle_question"]]
                  placeholderImage:nil
                         completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, NSURL *imageURL)
                        {
                            if(error)
                            {
                                 // image is not available
                            }
                            else
                            {
                                 // image is available
                            }
                       }];
