title: UIScrollView needs a touch before I can scroll
body: <p>I have a really strange behavior of my UIScrollView. It needs a touch before it can scroll, so it scrolls first on the second touch.</p>
  
  <p>I set the ContentSize in the LayoutSubview, so I can see that the content size is bigger than its size (it also show the scrollview indicator) when the scrollview is loaded.</p>
  
  <p>Any ideas why this happends?</p>
