After pushViewController, how to disable the backBarButtonItem?

Question

After pushViewController, how to disable the backBarButtonItem, that going back will not be possible?

tnx :)

Answer 1

navigationItem.hidesBackButton = YES

Answer 2

Another option is to simply not set the navigation controller's back button, when pushing a new view controller. It's not a requirement.

Answer 3

I ran into this issue and used following to hide the nav bar:

[self.navigationController setNavigationBarHidden: YES animated:YES];
