title: UIVIew inside UIScrollView bounces back
body: <p>MY app is for iPad using Storyboards with two scenes.  On one scene, I have a UIScrollView that contains a UIVIew.  It scrolls, but bounces back immediately, rendering itself useless.  The size of the UIScrollView is 768x590; the size of the UIView is 768x1590; ContentSize of the UIScrollView is 768x590.  This is an image of the UIScrollView settings:

  <p>(I have looked at SO and Google for the past 6 hours, tried a lot of stuff, but nothing works.  I have also done a CMD + Option + K (Clean) several times, and that didn't help either.</p>
  
  <p>Why does it not scroll properly?  </p>
