title: How to pause a UIImageView animation
body: <p>I have an animation that I'm displaying using a UIImageView:</p>
  
  <pre><code>imageView.animationImages = myImages;
  imageView.animationDuration = 3;
  [imageView startAnimating];
  </code></pre>
  
  <p>I know I can stop it using stopAnimating, but what I want is to be able to pause it. The reason is that when you call stop, none of your animation images are displayed, whereas I would like the last one that is up at the time when I hit a button to stay up.</p>
  
  <p>I have tried setting the duration to a much larger number, but that causes all the images to disappear as well. There must be a really basic way to do this?</p>
