How to hide a navigation bar from one particular view controller

Question

I've created a two splash screen iPhone app. Afterwards user is taken to first view. I've added a UINavigationController. It works perfectly fine.

How do I remove the navigation bar for the opening view alone?

MainWindow

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {       self.splashScreen = [[SplashScreen alloc]                  initWithNibName:@"SplashScreen"                  bundle:nil]; if (self.pageController == nil) { openingpage *page=[[openingpage alloc]initWithNibName:@"openingpage" bundle:[NSBundle mainBundle]];     self.pageController = page;     [page release]; } [self.navigationController pushViewController:self.pageController animated:YES];  [window addSubview:splashScreen.view];   [splashScreen displayScreen]; [self.window makeKeyAndVisible];  return YES;  } 

Answer 1

Try this method inside a view controller:

// swift self.navigationController?.setNavigationBarHidden(true, animated: true)  // objective-c [self.navigationController setNavigationBarHidden:YES animated:YES];

More clarifications:

UINavigationController has a property navigationBarHidden, that allows you to hide/show the navigation bar for the whole nav controller.

Let's look at the next hierarchy:

--UINavigationController ------UIViewController1 ------UIViewController2 ------UIViewController3 

Each of three UIViewController has the same nav bar since they are in the UINavigationController. For example, you want to hide the bar for the UIViewController2 (actually it doesn't matter in which one), then write in your UIViewController2:

- (void)viewWillAppear:(BOOL)animated {     [super viewWillAppear:animated];     [self.navigationController setNavigationBarHidden:YES animated:YES];   //it hides the bar }  - (void)viewWillDisappear:(BOOL)animated {     [super viewWillDisappear:animated];     [self.navigationController setNavigationBarHidden:NO animated:YES]; // it shows the bar back }
