Question

My UIViewControllers are pushed inside a navigationController.What I want to know is…what method gets called when I go from the current UIViewController to the previous one or forward?

I checked with viewDidUnLoad but this doesn’t get called.

Any idea?Thank you:)

These are called :

- (void)viewDidAppear:(BOOL)animated
- (void)viewDidDisappear:(BOOL)animated

- (void)viewWillAppear:(BOOL)animated
- (void)viewWillDisappear:(BOOL)animated
