如何更改状态栏颜色？

Question

In my app, I am using an image as the background for my ViewController's . For the status bar in the project settings I set: Status Bar Style - Default . I don't use anything else for the status bar.

The problem is when the iOS dark mode is enabled my status bar goes white. And I need it to stay black. How to fix it?

Also I don't want to turn off iOS dark/light mode supporting in the app. So the Appearance Light in the Info.plist doesn't quite work for me.

Set your status bar style to dark content:

After that add in your info.plist View controller-based status bar appearance and set it to NO

UPDATE

if you want dark content only in determinate controller add setNeedsStatusBarAppearanceUpdate in viewWillAppear and after that override preferredStatusBarStyle:

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    setNeedsStatusBarAppearanceUpdate()
}
override var preferredStatusBarStyle: UIStatusBarStyle {
    if #available(iOS 13.0, *) {
        return .darkContent
    } else {
        return .default
    }

Begin with navigation Controller:

In your Scene delegate declare your first navigation controller:

func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
    // Use this method to optionally configure and attach the UIWindow `window` to the provided UIWindowScene `scene`.
    // If using a storyboard, the `window` property will automatically be initialized and attached to the scene.
    // This delegate does not imply the connecting scene or session are new (see `application:configurationForConnectingSceneSession` instead).
    
    guard let windowScene = (scene as? UIWindowScene) else { return }
    window = UIWindow(windowScene: windowScene)
    window?.makeKeyAndVisible()
    let controller = UINavigationController(rootViewController: FirstViewController())
    controller.navigationBar.barStyle = .black
    window?.rootViewController = controller
}

in SecondViewController override the status bar style

override var preferredStatusBarStyle: UIStatusBarStyle {
    if #available(iOS 13.0, *) {
        return .darkContent
    } else {
        return .default
    }
}

For each ViewController you can set status bar color with simple override method.

override var preferredStatusBarStyle: UIStatusBarStyle {
    if #available(iOS 13, *) {
        return .darkContent
    } else {
        return .default
    }
}

Don't forget to set View controller-based status bar appearance to YES in your Info.plist.
