motionEnded methond not working with TabBarController iPhone

[ekam]

Hello Guys,

I can I make motionEnded work in one of my viewController inside the tabbarcontroller.

-(BOOL)canBecomeFirstResponder
{
* * return YES;
}
In viewDidLoad I got

[self becomeFirstResponder];

- (void)motionEndedUIEventSubtype)motion withEventUIEvent *)event
{
* * if (motion == UIEventSubtypeMotionShake )
* * {
* * * * NSLog(@"motioned");

* * }
}
