How do I change the title of the “back” button on a Navigation Bar

The Situation:
I have a UIViewController that is governed by a navigation controller. I am able to set the title of the navigation bar covering the UIViewController by simply calling self.title = @"title". But, I want to be able to set the back button text of the navigation bar, too (for different languages n' such..)

The Problem:
I don't know how to set the back button's text.

The Question:
How do I set the back button of the UINavigation bar (programmatically not in IB)?

Answer 1

The setTitle way - though may seem to work, is incorrect. If you pay attention closely, you will notice that the navigation item changes to the new title while the new view is animated into view via pushViewController. The fact that you have to restore your title in viewWillAppear is kludgy, which further suggests its hack nature.

The correct way is to do the following before your pushViewController:

UIBarButtonItem *backButton = [[UIBarButtonItem alloc] 
                                initWithTitle: @"Back Button Text" 
                                style: UIBarButtonItemStyleBordered
                                target: nil action: nil];

[self.navigationItem setBackBarButtonItem: backButton];
[backButton release];
