title: Add Image to UIAlertAction in UIAlertController
body: <p>I have seen a couple screen shots of a UIAlertControllers with an image on the left of the row but I do not seen it in the documentation. An example visual is <a href="https://i.stack.imgur.com/4H1Ad.png" rel="noreferrer"><img src="https://i.stack.imgur.com/4H1Ad.png" alt="http://imgur.com/SISBvjB"></a>
  Here is the code that I have for my controller right now:       </p>
  
  <pre><code>UIAlertController * view =   [UIAlertController
                                   alertControllerWithTitle:@"My Title"
                                   message:@"Select you Choice"
                                   preferredStyle:UIAlertControllerStyleActionSheet];
      UIAlertAction* ok = [UIAlertAction
                           actionWithTitle:@"OK"
                           style:UIAlertActionStyleDefault
                           handler:^(UIAlertAction * action)
                           {
                            }];
      [view addAction:ok];
      [self presentViewController:view animated:YES completion:nil];
  </code></pre>
