So, first of all
- (void)viewWillDisappear:(BOOL)animatedis a method specific toUIViewControllerclass.Second, this method shouldn't be called directly from the code, this method is called automatically when a
UIViewControlleris removed from a view hierarchy. (check UIViewController specs)So in order to handle this method call, you have to implement it in your custom
UIViewControllerclass (do not forget to call[super viewWillDisappear:animated]). Whenever your customUIViewControllerview will disappear from the screen (is popped from the stack or otherUIViewControlleris added to the stack) this method will be called.
