title: Iphone sequential animation with setAnimationDelay
body: <p>I'm trying to chain animation events. The application I'm coding for work has a multiple choice quiz. First you pick your multiple choice answer. The quiz view fades away. Then a label ("correct" or "incorrect") fades in and then fades out. Finally the quiz fades back in again. The events are called and handled by a main viewController. I know I can chain events with the setAnimationDelegate and setAnimationDidStopSelector but I think it'll be easier and more clear to simply use setAnimationDelay so that all animations have time to finish before the next one fires. </p>
  
  <p>I made this function that exists in the class that holds the "correct" "incorrect" label. </p>
  
  <pre><code>- (void)showIncorrect:(float)duration withDelay:(float)delay{
  labelView.text = @"Incorrect!";
  labelView.textColor = [UIColor redColor];
  
  [UIView beginAnimations:nil context:NULL];
      [UIView setAnimationDelay:delay];
      [UIView setAnimationDuration:(duration/2)];
      self.alpha = 1.0;
  [UIView commitAnimations];
  
  [UIView beginAnimations:nil context:NULL];
      [UIView setAnimationDelay:(duration/2+delay)];
      [UIView setAnimationDuration:(duration/2)];
      self.alpha = 0.0;
  [UIView commitAnimations];
  </code></pre>
  
  <p>}</p>
  
  <p>Can someone tell my why the first animation block is ignored? I've tried to nest one animation block into the other and this does not work either.</p>
