title: UIActionSheet is not showing separator on the last item on iOS 7 GM
body: <p>It could be probably a bug on iOS7. But the last button is not separated from the previous one<img src="https://i.stack.imgur.com/LB1Yw.png" alt="UIActionSheet is missing separator on the last button"></p>
  
  <p>As you can see from the image. This happens on both Simulator and device using iOS7 GM.
  Does everyone else has the same problem?</p>
  
  <pre><code>UIActionSheet *actionSheet = [[UIActionSheet alloc]
                 initWithTitle:@"Title"
                 delegate:self
                 cancelButtonTitle:nil
                 destructiveButtonTitle:nil
                 otherButtonTitles:@"First", @"Second", @"Third", @"Fourth", nil];
  [actionSheet showInView:self.view];
  </code></pre>
  
  <p>As you can see the code is quite simple.
  Any idea on how to fix the problem? Or some third party library I can use instead of UIActionSheet ?</p>
