Set the title of Navigation Bar created in Interface Builder

UINavigationBars manage a stack of UINavigationItems much like a UINavigationController manager a stack of UIViewControllers.  

To set what is visible directly, you should use either pushNavigationItem:animated: or setItems:animated: using the navigationItem of the view controller you want the bar to reflect.

eg:

self.navigationItem.title = @"A custom title";

[self.navigationBar pushNavigationItem:self.navigationItem animated:NO];

The above code that you have a property navigationBar which references the stand-alone navigation bar.

If you don't want to manage it yourself, you can do as mplappert suggested and nest your view controller (witout a stand-alone UINavigationBar) in a UINavigationController and present the navigation controller modally instead of your view controller.

or

self.navigationBar.topItem.title = title;

where navigation bar is your outlet.
