Question

I’m developing an iOS 4 application with latest SDK and XCode 4.2.

I’m using an UINavigationController and I don’t want to show Navigation Bar. To do that, I use this code on AppDelegate:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
    // Override point for customization after application launch.
    if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone)
    {
        self.viewController = [[[ViewController alloc] initWithNibName:@"ViewController_iPhone" bundle:nil] autorelease];
    }
    else
    {
        self.viewController = [[[ViewController alloc] initWithNibName:@"ViewController_iPad" bundle:nil] autorelease];
    }

    navController = [[UINavigationController alloc] initWithRootViewController:self.viewController];
    navController.navigationBar.hidden = YES;

    self.window.rootViewController = navController;
    [self.window makeKeyAndVisible];
    return YES;
}

But, this line, navController.navigationBar.hidden = YES; doesn’t work. I don’t see navigation bar on first view controller, but I see it on others views.

Any clue?

Answer 1

I have achieved this doing the following:

1. Setting navController.NavigationBar.hidden = YES; in AppDelegate, after alloc it.
2. Setting [navController setNavigationBarHidden:YES animated:YES]; on viewWillAppear: on every viewController that I pust to navController.
