title: scrollViewDidEndScrollingAnimation doesn't get called
body: <p>I have a simple UIScrollView and a UIPager, whenever I scroll through the scrollview I want to change my pager, but for some reason <code>(void)scrollViewDidEndScrollingAnimation:(UIScrollView *)scrollView</code> isn't being called.</p>
  
  <p>My delegate is working since <code>(void)scrollViewDidScroll:(UIScrollView *)scrollView</code> just works, am I forgetting something here?</p>
  
  <p>Or is there another way you can change a <code>UIPager</code> when the scrollview is being scrolled through?</p>
