title: iPhone OS: Tap status bar to scroll to top doesn't work after remove/add back
body: <p>Using this method to hide the status bar:</p>
  
  <pre><code>[[UIApplication sharedApplication] setStatusBarHidden:YES animated:YES];
  </code></pre>
  
  <p>When setting "hidden" back to NO, the tap-to-scroll-to-top (in UIWebView, UITableView, whatever) doesn't work any more, and requires a restart of the app to get the functionality back.</p>
  
  <p>Is this a bug (I filed a rdar anyhow) or have I missed a step? Should I perhaps expect this behavior since the statusBar "loses touch" somehow with the respective view?</p>
