title: UIScrollView bad contentSize height when in Landscape (ipad)
body: <p>I've a problem using a UIScrollView with subviews and vertical scrolling. </p>
  
  <p>When in portrait mode it scrolls fine, but when in landscape, even if I set an arbitrary value (let's say 1400px), it doesn't really scroll along that size, removing around 400 pixels and it stops before the content is fully visible.</p>
  
  <p>Any ideas?</p>
