UINavigationController without navigation bar?

I have a universal app, and on the iPad version I'm using UISplitViewController to create an interface similar to the Mail app.

I was having trouble pushing new Detail views, so I decided to use a UINavigationController so I could just push and pop views as needed. However, I do not want to use the navigation view or a toolbar. But no matter what I do, I can't hide the navigation bar.

I've tried unchecking "Shows Navigation Bar" in IB, and I've also tried setting:

[self.navigationController setNavigationBarHidden:YES];

in the viewDidLoad/viewDidAppear/viewWillAppear. I've also tried it in each of the views that will be pushed. Nothing works.

Is there something I'm missing here? Is it possible to have a UINavigationController without a toolbar or navigation bar?

You should be able to do the following:

self.navigationController.navigationBar.isHidden = true //Swift 5

where self.navigationController is (obviously) an instance of UINavigationController. Seems to work for me, but I only briefly tested it before posting this.

In Xcode 4.3.2:

1. Select the navigation controller in the storyboard

2. Select the Attributes Inspector in the (right) Utilities panel

3. Under the Navigation Controller category you have two check boxes:

   [] Shows Navigation Bar

   [] Shows Toolbar

Worked for me...

If you want no navigation bar, and you want the content to be adjusted up to where the navigation bar normally would be, you should use

self.navigationController.navigationBarHidden = YES;

This gives you a result like this:

Whereas self.navigationController.navigationBar.hidden = YES; gives you a space where the navigationBar should be. Like this:

Swift 4

I hide it in viewWillAppear

     override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)

        self.navigationController?.isNavigationBarHidden = true;
    }

Then you can put it back when you push a segue (if you want to have the back button on the next view)

     override func prepare(for segue: UIStoryboardSegue, sender: Any?) 
     {
        self.navigationController?.isNavigationBarHidden = false;
     }

Swift 3 Programmatically

self.navigationController.isNavigationBarHidden = true

or

self.navigationController.navigationBar.isHidden = true

Note: I didn't see a difference between these two approaches testing on iOS 10.

All these answers still leave a space at the top for the status bar - add this line to remove that as well:

navController.navigationBar.isHidden = true
navController.accessibilityFrame = CGRect.zero
