title: Getting the rect of the rotated view in willAnimateFirstHalfOfRotationToInterfaceOrientation:duration:
body: <p>I am trying to animate between portrait and landscape orientations by hooking the various autorotation methods in <code>UIViewController</code>.  Due to some subtleties of my view hierarchy, I'd like to set the frame of a child <code>UIScrollView</code> in the first half the animation and then scroll into position during the second half.  This requires knowledge of the final, rotated frame of my view from within <code>willAnimateFirstHalfOfRotationToInterfaceOrientation:duration:</code></p>
  
  <p>The system must know this frame in order to perform the rotation animation, but is it accessible to <code>UIViewController</code> subclasses?  If not, are my only options to hardcode the rotated frame or perform all layout in <code>didRotateFromInterfaceOrientation...</code>?</p>
  
  <p>Thank you.</p>
