title: Flip UIImageViews for Right to Left Languages
body: <p>iOS automatically flips the entire <code>ViewController</code> when using a RTL language like Arabic and does a great job with most of the layout, especially text. The default behavior is to flip the layout but leave <code>UIImageViews</code> the same orientation (since you generally don't want to reverse images). </p>
  
  <p>Is there a way to specify that some images should be flipped (such as arrows) when the phone is set to a RTL language?</p>
