title: Can I somehow get the scrollViewDidScroll: UIScrollView Delegate method from UIPageViewController?
body: <p>I have an array of <code>UIViewController's</code> that I want to be able to scroll up and down between.  I have started with UICollectionView, but that doesn't provide the rotation that I want.  I tried using UIPageViewController, but it doesn't use view reuse and I can't adjust the transition using the x or y offset.</p>
  
  <p>I have a workaround in mind for the view reuse, but I would also need to get the "scrollViewDidScroll:" calls from the <code>UIScrollView</code> that the <code>UIPageViewController</code> is using.  I didn't find anything useful in the <code>UIPageViewController</code> delegate.</p>
  
  <p>Does anyone know of a workaround for getting the current scroll position or offset of a <code>UIPageViewController</code>?</p>
