Storyboard - Hiding top bar of navigation controller programmatically

Question

I\'m using a storyboard and I\'m trying to hide a top bar of my main navigation controller when a certain button is pressed (or function is called). I know I have to initial

Answer 1

SetRoot RootViewController after Changing the Properties.

  UIStoryboard *storyBoard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];

// Create Navigation controller with RootViewController
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:[storyBoard instantiateViewControllerWithIdentifier:@"MyRootViewController"]];

Setting RootViewController

 [appDelegate.window setRootViewController: navController];

or else you Can Do in any ViewController

[self.navigationController setNavigationBarHidden:YES animated:YES];

Answer 2

In Xamarin.iOS

base.NavigationController.NavigationBarHidden = true;

Answer 3

Finally solved it. You should always hide navigation bar only through viewController.

In my question above I instantiated a whole new navigationController which didn't point at the real navController on the screen. You can obtain the "real" one through the view controller like this:

[viewController.navigationController setNavigationBarHidden:YES animated:YES];

Answer 4

I faced same problem, this worked for me

navController.navigationBar.hidden = YES;

Answer 5

The answers are correct. Just want to add that you probably want to put back the navigation bar when leaving the view as other views might use it and when you hide for one its hidden for all.

override func viewDidLoad() {
        super.viewDidLoad()
        self.navigationController?.navigationBar.isHidden = true
    }

and before you leave the view:

override func viewWillDisappear(_ animated: Bool) {
      super.viewWillDisappear(animated)
      self.navigationController?.navigationBar.isHidden = false
}

Answer 6

There are 2 ways to hide top bar of Navigation Controller:

1) Programatically

[self.navigationController setNavigationBarHidden:YES animated:YES];

2) Using Interface Builder

You can uncheck "Shows Navigation Bar" in property list of Navigation Controller.

Please make sure you have selected scene which contain Navigation Controller. Example image of scene.
