How to detect Orientation Change in Custom Keyboard Extension in iOS 8?

Question

In Custom Keyboard Extension , we can\'t use

`didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation` 

and

Answer 1

Before iOS 8.3, you have to use

-(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
                               duration:(NSTimeInterval)duration

This one does not work (it should be a bug):

-(void)viewWillTransitionToSize:(CGSize)size
      withTransitionCoordinator:(id)coordinator

On iOS 8.3 and later, you'd better use

-(void)viewWillTransitionToSize:(CGSize)size
      withTransitionCoordinator:(id)coordinator

because

-(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
                               duration:(NSTimeInterval)duration

is deprecated.
