Sent to the view controller before performing the first half of a user interface rotation.

The default implementation of this method does nothing.
This method is called from within the animation block used to rotate the view and slide the header and footer views out. You can override this method and use it to configure additional animations that should occur during the first half of the view rotation. For example, you could use it to adjust the zoom level of your content, change the scroller position, or modify other animatable properties of your view.
At the time this method is called, the
interfaceOrientation property is still set to the old orientation.
Called just before releasing the controller's view from memory.
Called when the controller's view is released from memory.
A Boolean value indicating whether the view should underlap the status bar.
Returns the header view to transition during an interface orientation change.
Returns the footer view to transition during an interface orientation change.
Convenience property that provides the current orientation of the interface, meaningful only if the view controller is taking up the full screen.
