我的實現（基于Eran Talmor）：

沒必要application.applicationSupportsShakeToEdit = YES;

• Set the applicationSupportsShakeToEdit property in the App's Delegate:

- (void)applicationDidFinishLaunching:(UIApplication *)application {

        application.applicationSupportsShakeToEdit = YES;

[window addSubview:viewController.view];
[window makeKeyAndVisible];
}

• Add/Override canBecomeFirstResponder, viewDidAppear: and viewWillDisappear: methods in your View Controller （這個View controller必須是頂層的）:

-(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 (模擬器中響應motionBegan, motionEnded，但真實機器iphone4中只能響應motionBegan):

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