title: Rotating a UIAlertView
body: <p>I've created a custom UIAlertView (by subclassing it and messing around with its <em>show</em> function) that has some custom subviews and is of non-standard size.</p>
  
  <p>It works ok when I create and display it, however, when the device is rotated, the alert rotates and then returns to its default size.</p>
  
  <p>Any ideas what functions to override - or should I tweak the UIViewController?</p>
  
  <p>thanks,
  Peter</p>
