title: How to connect UIScrollView to IBOutlet
body: <p>I have an iPad app using Storyboards.  I have a UIView that I have split into 2 areas; let's call them "top" (contains a UIView) and "bottom" (contains a UIScrollVIew, with a UIView sub-view).  In both cases I draw on the UIViews; the difference is the UIView which is a subv iew has to be scrolled.</p>
  
  <p>My question is how do I connect the UIScrollView to an IBOutlet so I can set the ContentSize?  And where do I place the IBOutlet definition, in AppDelegate? </p>
