Question

I am having an issue: I have a tab-bar based app. In MainWindow.xib for the tab that shows the nav controller it links to RootViewController.xib.
in RootViewController.xib I have created a navigation controller and have added a table view.
in RootViewController in viewDidLoad i have [self.view addSubview:navController.view];.
The tableview and navigation controller work well for navigation. pressing a cell pushes the controller, and bar buttons work in the pushed controller.
But when I use self.navController.navigationItem.rightBarButtonItem = barButton; nothing shows up at all. also changing self.navController.navigationItem to self..navigationItem ect.. doesn’t help. What do you think the problem could be? I appreciate every answer.
fyi the barbuttonitem is setup with:

UIBarButtonItem *barButton = [[UIBarButtonItem alloc] initWithTitle:@"Help" style:UIBarButtonItemStylePlain target:self action:@selector(help)];
