IPhone UINavigationController inside UIViewController

Steps:

  • List item
  • Create a project called Nav.
  • Create a new UIViewControllerBaseViewController (with XIB) and FirstViewController (with XIB).

  • In NavAppDelegat.hspecify the baseController variable

    @interface NavAppDelegate : NSObject <UIApplicationDelegate> {
BaseViewController *baseController;
}
@property (nonatomic, retain) IBOutlet BaseViewController *baseController;

  • In NavAppDelegat.madd baseController to the window:

    @synthesize baseController;
(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    
[self.window addSubview:baseController.view];
[self.window makeKeyAndVisible];
return YES;
}

  • Open the BaseViewController.xib file and add UINavigationController, set its root view controller and XIB class to FirstViewController (in the inspector).

  • Also connect the variable navigationController with UINavigationController.

I believe this should show me a FirstViewController with a navigation bar. If I do this directly on MainWindow.xib, everything works as I expected, but here I do not see the navigation bar. What am I missing? thank!

UPDATE: , UINavigationController (BaseViewController.xib ) MainWindow.xib, .
