接口方向更改时的iOS6更新视图

Question

I need to reposition a UIPopoverController when interface orientation change. In io5 I just did everything in: willRotateToInterfaceOrientation

I know I can listen to UIDeviceOrientationDidChangeNotification in IOS6, but I only want interface orientation calls.

Answer 1

The ideas behind ios6 rotation are that some views, like popovers, dont really have an orientation. as they dont fill the screen.

To re-layout the view as the size of the popover changes layout your view in -(void)viewWillLayoutSubviews in your popover's content view controller and ajust the views as needed to the new size. Animatable changes are animated.
