Question

I’ve I have a simple noob question, I would like to hide the navigation bar of a UINavigationController, but I’m pretty sure I`m not calling the right object .

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    UIViewController *rootViewController = [[[TestViewController alloc] init] autorelease];
    viewController = [ [UINavigationController alloc] initWithRootViewController:rootViewController];

    [window addSubview:viewController.view];
    [window addSubview: rootViewController.view];
    [window makeKeyAndVisible];
    return YES;
}

Now, I`ve tried, this :

-(void)hideBar {


    viewController.navigationBarHidden = YES;
}

It is complaining that “navigationBarHidden” not found on object type UIViewController, obviously I would need to call the UINavigation controller instead, but that’s where I’m stuck …

Answer 1

Try:

[self.navigationController setNavigationBarHidden:YES];

within your TestViewController. A good place is in viewDidLoad

Also, while we’re at it, remove the line [window addSubview:rootViewController.view];, you don’t need it.
