Rotating a UIView programmatically

Question

Should setting an autoresizeMask on a subview and autoresizesSubviews on the superview automatically resize and rotate the view if the return value for shouldAutoRotateTo... is YES?

Because its not. I have a scrollView and pageControl on my MainWindow, and the scroll view subviews are loaded from xibs.

Consequently, do i need to change the frame / bounds to reposition the view? Where do i do this if needed? All the examples i tried on Apple's source code, do this automatically.

Thanks.
