Navigation Bar Behind Status Bar

by Ryan Hedges

You might find yourself in an situation where you want to use the UINavigationBar API to create a navigation bar in one of your views. But it doesn’t look quite right. It doesn’t extend up behind the status bar like you’ve seen it do countless times before when using a UINavigationController. What gives? How do you extend the navigation bar behind the status bar in your iOS app?

Navigation Bar not behind Status Bar

Solution

The solution is actually really simple to implement, but how to do it using swift may prove to be more challenging to find online.

All you need to do is extend an object, like your view controller, to conform to the UINavigationBarDelegate and implement position(for:) to return UIBarPosition.topAttached

class SomeViewController: UIViewController {

    private let navigationBarView: UINavigationBar = {
        let nav = UINavigationBar(frame: .zero)
        // Configure navigation bar...
        return nav
    }()

    override func viewDidLoad() {
        super.viewDidLoad()
        view.backgroundColor = UIColor.init(red: 187/255, green: 42/255, blue: 97/255, alpha: 100)

        // Assign your delegate object
        self.navigationBarView.delegate = self

        let navBar = navigationBarView
        view.addSubview(navBar)

        navBar.translatesAutoresizingMaskIntoConstraints = false
        navBar.leadingAnchor.constraint(equalTo: view.leadingAnchor).isActive = true
        navBar.trailingAnchor.constraint(equalTo: view.trailingAnchor).isActive = true
        navBar.topAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor).isActive = true

        // Any other view needs
    }
}

extension SomeViewController: UINavigationBarDelegate {
    func position(for bar: UIBarPositioning) -> UIBarPosition {
        return UIBarPosition.topAttached
    }
}

Navigation Bar not behind Status Bar

Please note, you may want to handle the delegate function more gracefully depending on your needs.

extension SomeViewController: UINavigationBarDelegate {
    func position(for bar: UIBarPositioning) -> UIBarPosition {
        guard self.navigationBarView == bar as? UINavigationBar else {
            return bar.barPosition
        }
        return UIBarPosition.topAttached
    }
}

Hopefully this helps you continue creating a UINavigationBar with the look and feel that you want for your application.
