title: Resizing a UIView to make it scrollable in a UIScrollView
body: <p>I added a UIScrollView in my appDelegate, and then did </p>
  
  <pre><code>scrollView.contentSize = CGSizeMake(720, 480);
  scrollView.showsHorizontalScrollIndicator = YES;
  scrollView.showsVerticalScrollIndicator = YES;
  scrollView.delegate = self;
  [scrollView addSubview:viewController.view];
  [window makeKeyAndVisible];
  </code></pre>
  
  <p>Where view Controller loads up a UIView.  In IB, I set the size of the UIView to be 720x480, but it's not showing up any larger when I run.   I can scroll around my UIView to blank white space that is 720x480, but I want my UIView to be resized to this size too.  I checked the arguments in the initial drawRect rect, and they are still only 320x480, so it seems that I have to do something else to set the size of my UIView, other than resize it in IB?</p>
