title: UIView in UIScrollView not scrolling
body: <p>I am using the Xcode storyboard interface builder and I created a view controller with a UIScrollView that only has a single child UIView. This child UIView has many labels/buttons etc attached and exceeds the screen size height wise, however when I run my app, the view does not scroll for some reason.</p>
  
  <p>Here is a picture of the ViewController structure:

  <p>What am I doing wrong?</p>
