How to get the status bar height in iOS 13?

Question

In iOS 13 UIApplication.shared.statusBarFrame.height warns

'statusBarFrame' was deprecated in iOS 13.0: Use the statusBarManager property of the window scene instead.

How do you get the status bar height without using a deprecated API in iOS 13?

Answer 1

As the warning hints, you can access the statusBarManager which has a statusBarFrame property. This is defined on your UIWindow 's windowScene .

let height = view.window?.windowScene?.statusBarManager?.statusBarFrame.height ?? 0

Answer 2

Try, I have tried it.

let window = UIApplication.shared.windows.filter {$0.isKeyWindow}.first        
let height = window?.windowScene?.statusBarManager?.statusBarFrame.height ?? 0

Answer 3

Solution:

This seems to work without any warning in iPhoneX+ devices as well.

Swift 4.2 / 5

if #available(iOS 13.0, *) {
    let window = UIApplication.shared.windows.filter {$0.isKeyWindow}.first
    statusBarHeight = window?.windowScene?.statusBarManager?.statusBarFrame.height ?? 0
} else {
    statusBarHeight = UIApplication.shared.statusBarFrame.height
}

Try it. Hope it Helps.

I had the same problem as MMV (see their comment on Jordan H's answer), view.window?.windowScene?.statusBarManager?.statusBarFrame.height returned nil near the launch of my app. Specifically view.window returned nil. I then tried searching through the windows property on UIApplication.shared:

for window in UIApplication.shared.windows

This returned two windows in my case. Both of the windows had equal, non-nil status bar heights. I'm not sure why there were two windows, but at least both had the same status bar heights. I accessed the status bar heights like so:

if let height = window.windowScene?.statusBarManager?.statusBarFrame.height

I decided in my case that since there could possibly be different heights to take the largest of the heights for my code. Here is the code I used for my application:

let statusBarHeight: CGFloat = {
    var heightToReturn: CGFloat = 0.0
         for window in UIApplication.shared.windows {
             if let height = window.windowScene?.statusBarManager?.statusBarFrame.height, height > heightToReturn {
                 heightToReturn = height
             }
         }
    return heightToReturn
}()

Hope this helps someone!

var statusBarHeight: CGFloat = 0
if #available(iOS 13.0, *) {
    statusBarHeight = UIApplication.shared.keyWindow?.windowScene?.statusBarManager?.statusBarFrame.height ?? 0
} else {
    statusBarHeight = UIApplication.shared.statusBarFrame.height
}

Answer 6

For the latest method of getting statusBarHeight, is as follows:

    private lazy var statusBarHeight: CGFloat = {
        var statusBarHeight: CGFloat = 0
        if #available(iOS 13.0, *) {
            let window = UIApplication.shared.windows.filter {$0.isKeyWindow}.first
            statusBarHeight = window?.windowScene?.statusBarManager?.statusBarFrame.height ?? 0
        } else {
            statusBarHeight = UIApplication.shared.statusBarFrame.height
        }
        return statusBarHeight
    }()

Answer 7

For Objective-C

I'm not sure what is alternative of filter in OC, so I used a for loop to get keyWindow . Well, the actual height I get in iPhone 12 is '47' and iPhone 8 with '20'.

    CGFloat statusBarHeight;
    if (@available(iOS 13, *)) {
        NSArray *windows = UIApplication.sharedApplication.windows;
        UIWindow *keyWindow = nil;
        
        for (UIWindow *window in windows) {
            if (window.isKeyWindow) {
                keyWindow = window;
                break;
            }
        }
        statusBarHeight = keyWindow.windowScene.statusBarManager.statusBarFrame.size.height;
        NSLog(@"statusBarHeight: %f", statusBarHeight);
    } else {
        statusBarHeight = UIApplication.sharedApplication.statusBarFrame.size.height;
    }

Answer 8

for iOS 13:

in your SceneDelegate :

func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
 if let windowScene = scene as? UIWindowScene {
    let window = UIWindow(windowScene: windowScene)
    let statusBarSize = windowScene.statusBarManager!.statusBarFrame
    ...// initialize your root view controller
 }
}

and if you want to pass the value to your View s, you can set the value as Environment and use it in your View s. example:

first we need to create our environment key:

struct StatusBarSizeEnvironmentKey: EnvironmentKey {
   public static let defaultValue: CGRect = CGRect()
}

extension EnvironmentValues {
  public var statusBarSize: CGRect {
    set { self[StatusBarSizeEnvironmentKey.self] = newValue }
    get { self[StatusBarSizeEnvironmentKey] }
  }
}

and set the value in SceneDelegate :

func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
 if let windowScene = scene as? UIWindowScene {
    let window = UIWindow(windowScene: windowScene)
    let statusBarSize = windowScene.statusBarManager!.statusBarFrame
    window.rootViewController = UIHostingController(rootView: YourView()
             .environment(\.statusBarSize, statusBarSize))
 }
}

Answer 9

Learning from the great answers already given here, using connectScenes from UIApplication , and we can make an extension:

extension UIApplication {
    var statusBarHeight: CGFloat {
        connectedScenes
            .compactMap {
                $0 as? UIWindowScene
            }
            .compactMap {
                $0.statusBarManager
            }
            .map {
                $0.statusBarFrame
            }
            .map(\.height)
            .max() ?? 0
    }
}

Usage:

let height = UIApplication.shared.statusBarHeight

stolen from accepted answer:

guard let sbheight = view.window?.windowScene?.statusBarManager?.statusBarFrame.height else {
     assertionFailure("usage error: VC lifecyclewise it becomes available no earlier than viewDidAppear")
}

Answer 11

UIApplication.shared.windowswindows was deprecated in iOS 15.0

iOS 15

 let statusBarHeight = UIApplication.shared.connectedScenes
        .filter {$0.activationState == .foregroundActive }
        .map {$0 as? UIWindowScene }
        .compactMap { $0 }
        .first?.windows
        .filter({ $0.isKeyWindow }).first?
        .windowScene?.statusBarManager?.statusBarFrame.height ?? 0

Answer 12

For Objective-C

- (CGFloat)statusBarHeight{
    UIWindowScene * scene = nil;
    for (UIWindowScene* wScene in [UIApplication sharedApplication].connectedScenes){
        if (wScene.activationState == UISceneActivationStateForegroundActive){
            scene = wScene;
            break;
        }
    }
    return scene.statusBarManager.statusBarFrame.size.height;
}

I think the above is OK too, @ChuckZHB's answer.

Answer 13

This only works if you have a single window app, which is all of the mobile apps and 99% of the iPad apps.

let height = UIApplication.shared.windows.first(where: \.isKeyWindow)?.windowScene?.statusBarManager?.statusBarFrame.height ?? 0

or if you like to break up the code a bit:

let window = UIApplication.shared.windows.first(where: \.isKeyWindow)
let height = window?.windowScene?.statusBarManager?.statusBarFrame.height ?? 0

Answer 14

Worked for me for iOS 15 and higher.

extension UIViewController {
    var statusBarHeight: CGFloat {
        guard
            let scene = UIApplication.shared.connectedScenes.first as? UIWindowScene,
            let height = scene.statusBarManager?.statusBarFrame.height
        else {
            return 0
        }
        return height
    }
}
