title: willAnimateRotationToInterfaceOrientation not being called in one subview while another is visible and rotated
body: <p>I have 3 subviews in a UITabBarController. The first tab's view has objects which are manually moved when willAnimateRotationToInterfaceOrientation is called. However, if another tab's view is visible on rotate, willAnimateRotationToInterfaceOrientation is never called, and the items on the first tab's view are not in the right place if I go back to the first tab.</p>
  
  <p>How can i manually move objects in one view on rotate when another view is visible?</p>
