iPhone: Setting Navigation Bar Title

Question

Hey all. I'm still pretty new to iPhone development, and I'm having a bit of trouble figuring out how to change the title of my Navigation Bar. On another question on this site somebody recommended using :

viewController.title = @"title text";

but that isn't working for me...Do I need to add a UINavigationController to accomplish this? Or maybe just an outlet from my UIViewController subclass? If it helps, I defined the navigation bar in IB and I'm trying to set its title in my UIViewController subclass. This is another one of those simple things that gives me a headache. Putting self.title = @"title text"; in viewDidLoad and initWithNibName didn't work either. Anybody know what's happening and how to get it happening right?

Thanks!

The view controller must be a child of some UINavigationController for the .title property to take effect. If the UINavigationBar is simply a view, you need to push a navigation item containing the title, or modify the last navigation item:

UINavigationItem* item = [[UINavigationItem alloc] initWithTitle:@"title text"];
...
[bar pushNavigationItem:item animated:YES];
[item release];

or

bar.topItem.title = @"title text";
