title: UIScrollView doesn't bounce
body: <p>I have a UIScrollView <strong>contained within a custom UIView</strong> with a content size larger than the ScrollView's frame.</p>
  
  <p>I am able to drag scroll as I expect, but the thing doesn't give me the rubber banding effect that you get with the UITableView or UIWebView. It just stops when you get to one of the extremes.</p>
  
  <p>I have set <code>bounce = YES</code>, is there something else I'm supposed to do?</p>
  
  <p>I read the docs, and they say I have to implement the delegate. I did that.</p>
  
  <p>They also say I should change the zoom levels, but I don't want the user to actually be able to zoom so I haven't set these.</p>
