I am trying to use the NSNotificationCenter to get UIMenuControllerDidShowMenuNotification from a UIWebView. I have the following code in my ViewDidLoad method:

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(menuControllerWillHide:) name:UIMenuControllerWillHideMenuNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(menuControllerWillShow:) name:UIMenuControllerWillShowMenuNotification object:nil];

And methods: - (void)menuControllerWillHide:(NSNotification *)notification {

}

• (void)menuControllerWillShow:(NSNotification *)notification { [[self navigationItem] setRightBarButtonItem:highlightBtn animated:NO]; }

But I never get the Notifications? Any help would be helpful
