I need to know when my view controller is about to get popped from a nav stack so I can perform an action.

I can\'t use -viewWillDisappear, because that gets called

    You can use this one:

    if(self.isMovingToParentViewController)
    {
        NSLog(@"Pushed");
    }
    else
    {
        NSLog(@"Popped");
    }
