cocoa touch - Changing the UIBackButtonItem title

Question

I have a navigationController-based app. I want to change the title of the back button for the root view controller. I have tried the following code in the rootViewController's viewDidLoad method, but no success:

self.navigationItem.backBarButtonItem.title = @"Back";

Any ideas?

Answer 1

I've had success by creating my own UIBarButtonItem instead of setting the title of the existing one:

UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:@"Back" style:UIBarButtonItemStylePlain target:nil action:nil];
self.navigationItem.backBarButtonItem = backButton;
[backButton release];
