The root view controller becomes the top view controller. For information on how the navigation bar is updated, see “Updating the Navigation Bar.”
UINavigationController popToRootViewControllerAnimated example.
Calling [self.navigationController popToRootViewControllerAnimated:YES] sets self.navigationController to nil. When you subsequently call [self.navigationController pushViewController:someOtherViewController] you are effectively sending a message to nil, which does nothing.
To workaround, simply set up a local reference to the navigationController and use that instead:
UINavigationController * navigationController = self.navigationController;
[navigationController popToRootViewControllerAnimated:NO];
[navigationController pushViewController:someOtherViewController animated:YES];

UINavigationController popToRootViewControllerAnimated example.
You can return to the first view with
[self.navigationController popToRootViewControllerAnimated:YES];
That being said, you can also remove a particular view controller, or navigate to a specific index in your view controller if you look at the example.
NSMutableArray *allViewControllers = [NSMutableArray arrayWithArray:navigationController.viewControllers];
// You can now manipulate this array with the methods used for NSMutableArray to find out / perform actions on the navigation stack
[allViewControllers removeObjectIdenticalTo: removedViewController];
// You can remove a specific view controller with this.
navigationController.viewControllers = allViewControllers;
[self.navigationController popToRootViewControllerAnimated:YES];
