iphone detect shake throughout app

Question

I need to have a function that detects a shake without having to add the - (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event in every viewController. But when I add the function to the appDelegate, the motion isn't detected. I tried NSNotificationCenter to no avail. I have ton's of viewControllers and adding the motionEnded-method to all of them would be tedious…

Any ideas?

Answer 1

you can add - (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event in the AppDelegate.window.

ps: subclass the UIWindow

Answer 2

Create a BaseViewController, put your shake detection methods there and make every controller inherit from it.
