title: Transparent space above 1st section in table view after rotate
body: <p>I have a split view controller, as the master view I have a UIViewController.  That UIViewController has a toolbar and a tableview inside it.</p>
  
  <p>If I rotate the the split view to portrait and then back to landscape I see a space above the tableview that is transparent.  When I scroll the tableview up a little I see the table contents appear in that space.</p>
  
  <p>Whats weird is that it only happens when I rotate the device and then rotate back again.  The table view is fine at first but something seems to get messed up after a couple of rotations.</p>
  
  <p>Here is a screenshot of it after I rotate a few times:

  <p>Here is a screenshot before the rotation  (looks great):

  <p>I have tried to force it to re layout with setNeedsLayout, but no luck.</p>
  
  <p>Any clue???</p>
