iPhone: Setting Navigation Bar Title

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";

if you are doing it all by code in the viewDidLoad method of the UIViewController you should only add self.title = @"title text";

something like this:

- (void)viewDidLoad {
    [super viewDidLoad];
    self.title = @"title";
}

you could also try self.navigationItem.title = @"title";

also check if your navigationItem is not null and if you have set a custom background to the navigationbar check if the title is set without it.

I had a navigation controllers integrated in a TabbarController. This worked 

self.navigationItem.title=@"title";

I guess you need a dynamic title that is why you don't set it in IB.

And I presume your viewController object is the one specified in the NIB?

Perhaps trying setting it to a dummy value in IB and then debug the methods to see which controller has the dummy value - assuming it appears as the title...
