• Add/Override canBecomeFirstResponder, viewDidAppear: andviewWillDisappear: methods in your View Controller （这个View controller必须是顶层的）:

-(BOOL)canBecomeFirstResponder { return YES;
} -(void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; [self becomeFirstResponder];
} - (void)viewWillDisappear:(BOOL)animated { [self resignFirstResponder]; [super viewWillDisappear:animated];
}

• Add the motionEnded or motionBegan method to your View Controller (模拟器中响应motionBegan, motionEnded，但真实机器iphone4中只能响应motionBegan):

- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event
{ if (motion == UIEventSubtypeMotionShake) { // your code }
}
