title: Action sheet doesn't show Cancel button on iPad
body: <p>On the iphone, this code shows the cancel button:</p>
  
  <pre><code>- (IBAction)buttonPressed
  {
      UIActionSheet *actionSheet = [[UIActionSheet alloc]
                                    initWithTitle:@"Are you sure?"
                                    delegate:self 
                                    cancelButtonTitle:@"No way!"
                                    destructiveButtonTitle:@"Yes, I'm sure!"
                                    otherButtonTitles:nil];
      [actionSheet showInView:self.view];
      [actionSheet release];  
  }
  </code></pre>
  
  <p>But on the iPad, only the destructive button shows.<br>
  What's the problem?</p>
