title: UIView animateWithDuration and UIProgressView setProgress
body: <p>I want to animate my <code>UIProgressView</code> progression from 0 to 1 during 10 seconds.</p>
  
  <p>Code:</p>
  
  <pre><code>[UIView animateWithDuration:10.0 animations:^{
      [_myProgressView setProgress:1 animated:YES];
  } completion:(BOOL finished)^{
      if (finished) NSLog(@"animation finished);
  }];
  </code></pre>
  
  <p>Animation is working fine except that completion and <code>NSLog</code> are always called instantly.</p>
  
  <p>I tried <code>animateWithDuration: withDelay:</code> but the delay is not respected and executed immediately.</p>
  
  <p>Has anyone encountered the same problem?</p>
  
  <p>Thanks for you help.</p>
