iOS how to remove back button?

Question

I have an application with a navigation bar that pushes to a login screen view controller and then pushes to a main menu. Is there any way I can remove the back button off the main menu, so the user is unable to go back to the login screen?

Thanks!

EDIT: Using Xcode 4.3 and doing all the leg work programmatically.

Answer 1

You can do:

[self.navigationItem setHidesBackButton:YES]; 

In your second view controller (the one you want to hide the button in).

Answer 2

Peters answer is correct, although I think the better question is why? In a schema like yours where you are wanting to login a user, instead of using a Pushed VC, present a Modal VC and use a delegate method to get back the userinfo that was obtained in the Login process. I can post a complete code example if you need it, but it sounds like you have the details worked out with your login process. Just use:

presentModalViewController 

instead of:

pushViewController 

That way, you don't have to worry about the navigation stack and doing something that isn't really in-line with the user interface guidelines.
