How to respond to touch events in UIWindow?

Question

Is it possible to handle touch events in the key UIWindow in the app Delegate or anywhere else?

Any help would be appreciated please.

Answer 1

UIWindow is a subclass of UIResponder, which has APIs for handling touch events (e.g., touchesBegan:withEvent:). It is possible then for you to subclass UIWindow, override the touch event handling APIs, and manage the touch events yourself.
