  <pre><code>[cell.imgMain sd_setImageWithURL:imageLoadUrl
                      placeholderImage:[UIImage imageNamed:@"*placeholder image*"]
                               options:SDWebImageRefreshCached];
  </code></pre>

                       placeholderImage:[UIImage imageNamed:@"wachizLogoIcon.png"]
                                success:^(NSURLRequest *request, NSHTTPURLResponse *response, UIImage *image) {
  
                                    cell.imgMain.image=image;
                                }
