title: UIView animation end
body: <p>I am using <code>UIView</code> animation in my app:</p>
  
  <pre><code>        [UIView beginAnimations:nil context:NULL];
          [UIView setAnimationDuration:1];
          //do some animation
          [UIView commitAnimations];
  </code></pre>
  
  <p>Now, there is a possibility that the animation would take a couple of seconds to finish. So, is there a way to know when the animation has ended? </p>
