title: using UIView animateWithDuration: delay: Xcode
body: <p>I am trying to use </p>
  
  <pre><code>[UIView animateWithDuration:1 delay:2 options:UIViewAnimationOptionCurveEaseIn animations:^{
  } completion:^ (BOOL completed) {}         ];
  </code></pre>
  
  <p>however no matter what number I put for the delay, there is no delay.<br>
  I am trying to have a series of buttons fade in one after the other when another button is touched. So I use a series of UIView animate  with various lengths of delay but they all show up at the same time no matter what time delay I enter.  Does anyone have some suggestions?</p>
