title: UIScrollView not working with [scrollView setScrollEnabled: YES]
body: <p>In my .h file, I have an IBOutlet declared like this:</p>
  
  <pre><code>IBOutlet UIScrollView *scrollView;
  </code></pre>
  
  <p>I wired my UIScrollView to File's Owner.</p>
  
  <p>In my .m file I have the following in viewDidLoad:</p>
  
  <pre><code>[scrollView setContentSize:CGSizeMake(320, 600)];
  [scrollView setScrollEnabled:YES];
  </code></pre>
  
  <p>But when I try to scroll, nothing happens. </p>
  
  <p>You don't need to set the UIScrollViewDelegate because I've had apps that scroll without using it.</p>
