Call an action when switching views

[lll3mk4]

Hello,

I would like to call a "save action" when I change views in a Navigation Based application. I have the save code but I need to know how to call that code when I go the the "Home" page of the app.


Thanks

viewWillAppear on your viewController?

I just tried that and still nothing.

If you're talking about the elusive "Back Button" on the navigation bar, try the UINavigationControllerDelegate method - (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated

Thank you! Would I put that in the AppDelegate.m or the ViewController.m
