title: how do I use UIScrollView in Interface Builder?
body: <p>While I've used <code>UIScrollView</code> successfully in the past by manipulating it programmatically, I'm having trouble getting it to work by setting it up exclusively in Interface Builder.  </p>
  
  <p>I have a simple "about" page in my iPhone app.  It has a <code>UITextView</code>, some icons, and links to my other apps.  I have added all of these views to my <code>UIScrollView</code>, arranging them so that their total size is > 480.  When I launch my app, the scrollview displays only the contents that fit on the screen, and nothing scrolls.</p>
  
  <p>Is it possible to do this entirely via IB, or must I manipulate the contentSize via code?</p>
