title: AFNetworking 2.0 setImageWithURLRequest
body: <p>I'm using this code when downloading images in one of my current projects and it's not working with AFNetworking 2.0. I tried going thru AFImageResponseSerializer but I can't find the right code to use.</p>
  
  <pre><code>[cell.posterImage setImageWithURLRequest:urlRequest placeholderImage:[UIImage imageNamed:@"placeholder.png"] success:^(NSURLRequest *request, NSHTTPURLResponse *response, UIImage *image) {
              cell.posterImage.image = image;
          } failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error) {
              NSLog(@"Request failed with error: %@", error);
          }];
  </code></pre>
  
  <p>Any suggestions on the new code used in AFNetworking 2.0? Thanks!</p>
