UISplitViewController rotations

How does a UISplitViewController know when it has rotated so that it can trigger the appropriate behavior with managing its views? Is th开发者_JAVA百科ere some way I can manually trigger it myself? I have a split view controller owning a view that is not at the root of my hierarchy, so it is not getting the rotation events that (I think) normally allow it to handle rotation behavior.

You can try to implement UISplitViewController delegate which is:

// Landscape mode

– splitViewController:willShowViewController:invalidatingBarButtonItem:

// Portrait mode

– splitViewController:willShowViewController:invalidatingBarButtonItem:

Since the masterView (left) will show/hide accordingly when the rotation occurs, I found this is more effective compared to handling the orientation changes if each view

I guess UiSplitViewController doesn't autorotate and iPad: SplitView does not rotate pretty much say that unless the controller's view is the root view, it won't work. Oh apple.

You could sign up for notifications of orientation changing, make sure you have shouldAutorotateToInterfaceOrientation set to YES for the rotations you want to support as well.
