Navigation bar not appeared?

I am using XCode 4.

In My application simple View Based Application.

I have no UINavigation controller allocated.

But I just want to use default property of UINAvigation controller.

I have done in

- (void)viewDidLoad
{
    [self.navigationController setNavigationBarHidden:NO animated:YES];
   // self.navigationItem.rightBarButtonItem=self.bbiAdd;

    [super viewDidLoad];

    // Do any additional setup after loading the view from its nib.
}

But I can not see the result ... I have done with inte开发者_开发知识库rface builder with this code....

You can't use the self.navigationController if you don't have an UINavigationController.

All you can do is add an UINavigationBar to your UIViewController.

Just Drag and Drop a UINavigationBar in your XIB, set the Title (if you want) for it and you are good to go.
