title: Autorotation lock, programmatically
body: <p>Does anybody know if there is a possibility to lock autorotation of iPhone programmatically for just one view?
  I want to make some kind of help with semi-transculent view, but I want to support only landscape orientation even all other views can rotate.
  So I wish to lock rotation when this view is on the top.</p>

  <p>EDIT: More details: one UIController has 7 UIView...and I wish to lock the autorotation just when the last one occurs on the top.</p>
