title: change position of cancel button in UIAlertView?
body: <p>I noticed that when I delete an app from my iPhone home screen, the alert view that appears shows a Delete button on the left and Cancel on the right. However, when I build a delete function within my app using UIAlertView, the buttons only seem to display with Cancel on the left and Delete on the right.</p>
  
  <p>I'd like my app to be consistent with the OS, but I can't figure out how to make the Cancel button appear first. Does anyone know?</p>
  
  <pre><code>UIAlertView *alert = [[UIAlertView alloc] 
                        initWithTitle:@"Delete Song" 
                        message:@"Are you sure you want to delete this song? This will permanently remove it from your database." 
                        delegate:self 
                        cancelButtonTitle:@"Cancel" 
                        otherButtonTitles:@"Delete", nil];
  </code></pre>
  
  <p>I tried setting alert.cancelButtonIndex = 1, but that had no effect.</p>
