Question

When creating a new nav-based iphone app, how do you add a button to the nav bar?

I’ve tried editing the rootviewcontroller.xib and adding a nav bar and nav item and bar button item, but it doesn’t seem to make any difference.

Is there a simple way of achieving this through IB, or do i have to duck into code somewhere?

Thanks

Unfortunately this requires a little bit of code. Create your UIBarButtonItem in interface builder and hook it up to an IBOutlet in your view controller. Then, in viewDidLoad:

- (void)viewDidLoad {
  [super viewDidLoad];

  // Assuming "myButton" is the UIBarButtonItem.
  self.navigationItem.leftBarButtonItem = myButton;
}

Assigning to rightBarButtonItem works similarly. See the UINavigationItem Class Reference for more information.
