I have a navigation based application that have a uinavigataioncontroller containing uitableviewcontrollers. I want to add buttons to the UINavigationbar of the uinavigataioncontroller, usually I write code to add these buttons, something like this:

UIBarButtonItem *saveButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemSave target:self action:@selector(saveClicked:)]; 
self.navigationItem.rightBarButtonItem = saveButton;
[saveButton release];

My idea now was to use interface builder instead. But I'm not sure how to do it. What I'm trying to do is to add a UINavigationItem in the xib file of the viewcontroller (my viewcontroller is called TextViewController), something like this:

But how can I make TextViewController use the UINavigationItem I added? The button I add doesn't show in the navigationbar.

Any ideas on how to do this? What am I missing?
