Question

I want to call a new view controller and remove the current view controller from the navigation controller stack. For example. I am in view controller A and I call B.

To remove the second-from-last navigation item:

NSMutableArray *navigationStack = [[NSMutableArray alloc] initWithArray: 
    self.navigationController.viewControllers];
[navigationStack removeObjectAtIndex:[navigationStack count] - 2];
self.navigationController.viewControllers = navigationStack;

For example, run this from viewDidLoad on controller C to remove controller B from the navigation stack.
