使用statusbarmanager

Question

this问题旋转：在ios13+上设置状态栏颜色（使用statusbarmanager）在如何将状态栏文本颜色设置为深色或uiviewController的dark或Light。

但没有关于如何动态更改状态栏外观的答案。

这仍然对我有用，但是自iOS 13：

以来，它已经被贬低了。

// inside a function of the viewController
//set the status bar background
overrideUserInterfaceStyle = darkMode ? .dark : .light
// on older iOS, this is not sufficient (tested and failed on ios 15)
setNeedsStatusBarAppearanceUpdate() 
// statusBarStyle is deprecated on iOS 13+
UIApplication.shared.statusBarStyle = nightMode ? .lightContent : .darkMode

这对我不起作用（加载视图时设置了状态栏样式，但以后不更新）：

override var preferredStatusBarStyle: UIStatusBarStyle {
    return darkMode ? .lightContent : .darkContent
}

Answer 1

info.plist

以下在控制器中给出的实施代码Appearance

我在

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
    }
    
    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        setNeedsStatusBarAppearanceUpdate()
    }
    

    /*
    // MARK: - Navigation

    // In a storyboard-based application, you will often want to do a little preparation before navigation
    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        // Get the new view controller using segue.destination.
        // Pass the selected object to the new view controller.
    }
    */

    override var preferredStatusBarStyle: UIStatusBarStyle {
        return UIScreen.main.traitCollection.userInterfaceStyle == .dark ? .lightContent : .darkContent
    }
}

中尝试了
