title: Animating a UIImageView with delay
body: <p>I am animating a UIImageView in this way:</p>
  
  <pre><code>int timerAnimation = 0.0f;
  
  for (UIImageView* img in imageArray) {
  
  timerAnimation = timerAnimation + 1.0f;
  
  [UIView animateWithDuration:1.0f
                        delay:timerAnimation
                      options:UIViewAnimationOptionCurveEaseIn
                   animations:^(void) {
                       img.frame = CGRectMake(20, img.frame.origin.y, 710, 60);
                   }
                   completion:NULL];
  </code></pre>
  
  <p>I want to reduce the delay time, but I noticed that if I put any value inferior than 1.0,</p>
  
  <p>e.g.</p>
  
  <pre><code>timerAnimation + 0.5f;
  </code></pre>
  
  <p>Then all the objects move at the save time, as if there was no delay. Why is this?</p>
