随着iOS 13的到来， statusBar 的视图不再可以通过以下方式访问：

value(forKey: "statusBar") as? UIView

由于：

由于未捕获的异常“NSInternalInconsistencyException”而终止应用程序，原因：“在 UIApplication 上调用 -statusBar 或 -statusBarWindow 的应用程序：必须更改此代码，因为不再有状态栏或状态栏窗口。在窗口场景中使用 statusBarManager 对象。

但目前尚不清楚它应该如何用于更改颜色，因为keyWindow?.windowScene?.statusBarManager它似乎不包含任何与之相关的内容。

我正在用 (iOS 10, *) 兼容性编译我的代码，所以我打算继续使用 UIKit。

关于这个主题的任何想法？

您可以添加一些条件或使用第一个条件。只需为 UIApplication 创建一些扩展。

extension UIApplication {
var statusBarUIView: UIView? {
    if #available(iOS 13.0, *) {
        let tag = 38482
        let keyWindow = UIApplication.shared.windows.filter {$0.isKeyWindow}.first

        if let statusBar = keyWindow?.viewWithTag(tag) {
            return statusBar
        } else {
            guard let statusBarFrame = keyWindow?.windowScene?.statusBarManager?.statusBarFrame else { return nil }
            let statusBarView = UIView(frame: statusBarFrame)
            statusBarView.tag = tag
            keyWindow?.addSubview(statusBarView)
            return statusBarView
        }
    } else if responds(to: Selector(("statusBar"))) {
        return value(forKey: "statusBar") as? UIView
    } else {
        return nil
    }
  }
}

更新：抱歉，我没有足够的时间在实际项目中对其进行测试，但它适用于“Hello world”应用程序。您可以阅读有关keyWindow和statusBarFrame的更多信息，以使其更好。

extension UIApplication {
var statusBarUIView: UIView? {

    if #available(iOS 13.0, *) {
        let tag = 3848245

        let keyWindow = UIApplication.shared.connectedScenes
            .map({$0 as? UIWindowScene})
            .compactMap({$0})
            .first?.windows.first

        if let statusBar = keyWindow?.viewWithTag(tag) {
            return statusBar
        } else {
            let height = keyWindow?.windowScene?.statusBarManager?.statusBarFrame ?? .zero
            let statusBarView = UIView(frame: height)
            statusBarView.tag = tag
            statusBarView.layer.zPosition = 999999

            keyWindow?.addSubview(statusBarView)
            return statusBarView
        }

    } else {

        if responds(to: Selector(("statusBar"))) {
            return value(forKey: "statusBar") as? UIView
        }
    }
    return nil
  }
}

不幸的是，Apple 弃用了一些上述访问状态栏和编辑其属性的方法。您将不得不StatusBarManager使用WindowScene. 以下方法适用于 iOS 13 及更高版本：

extension UINavigationController {

    func setStatusBar(backgroundColor: UIColor) {
        let statusBarFrame: CGRect
        if #available(iOS 13.0, *) {
            statusBarFrame = view.window?.windowScene?.statusBarManager?.statusBarFrame ?? CGRect.zero
        } else {
            statusBarFrame = UIApplication.shared.statusBarFrame
        }
        let statusBarView = UIView(frame: statusBarFrame)
        statusBarView.backgroundColor = backgroundColor
        view.addSubview(statusBarView)
    }

}

我以前遇到过这个问题。当我使用 XCode 11 和 Swift 5.0 运行此代码时，我的应用程序崩溃了。

以前的代码：-

UIApplication.shared.statusBarView?.backgroundColor = UIColor.init(red: 243/250, green: 243/250, blue: 243/250, alpha: 1)

刚刚更改为：-

if #available(iOS 13.0, *) {
    let statusBar = UIView(frame: UIApplication.shared.keyWindow?.windowScene?.statusBarManager?.statusBarFrame ?? CGRect.zero)
     statusBar.backgroundColor = UIColor.init(red: 243/250, green: 243/250, blue: 243/250, alpha: 1)
     UIApplication.shared.keyWindow?.addSubview(statusBar)
} else {
     UIApplication.shared.statusBarView?.backgroundColor = UIColor.init(red: 243/250, green: 243/250, blue: 243/250, alpha: 1)
}

现在我的问题解决了。快乐编码。

这在 Swift 5 中对我有用

   override func viewDidLoad() {
      super.viewDidLoad()

      if #available(iOS 13, *)
      {
          let statusBar = UIView(frame: (UIApplication.shared.keyWindow?.windowScene?.statusBarManager?.statusBarFrame)!)
          statusBar.backgroundColor = #colorLiteral(red: 0.2346, green: 0.3456, blue: 0.5677, alpha: 1)
          UIApplication.shared.keyWindow?.addSubview(statusBar)
      } else {
         // ADD THE STATUS BAR AND SET A CUSTOM COLOR
         let statusBar: UIView = UIApplication.shared.value(forKey: "statusBar") as! UIView
         if statusBar.responds(to:#selector(setter: UIView.backgroundColor)) {
            statusBar.backgroundColor = #colorLiteral(red: 0.2346, green: 0.3456, blue: 0.5677, alpha: 1)
         }
         UIApplication.shared.statusBarStyle = .lightContent
      }
   }

对于 swift 5.0，我这样做是为了更改背景颜色，

    if #available(iOS 13.0, *) {
           let window = UIApplication.shared.windows.filter {$0.isKeyWindow}.first 
           // Reference - https://stackoverflow.com/a/57899013/7316675
           let statusBar = UIView(frame: window?.windowScene?.statusBarManager?.statusBarFrame ?? CGRect.zero)
           statusBar.backgroundColor = .white
           window?.addSubview(statusBar)
    } else {
           UIApplication.shared.statusBarView?.backgroundColor = .white
           UIApplication.shared.statusBarStyle = .lightContent
    }

经过测试并且 100% 为我工作

func statusBarColorChange(){

    if #available(iOS 13.0, *) {

            let statusBar = UIView(frame: UIApplication.shared.keyWindow?.windowScene?.statusBarManager?.statusBarFrame ?? CGRect.zero)
            statusBar.backgroundColor = AppThemeColor
            statusBar.tag = 100
            UIApplication.shared.keyWindow?.addSubview(statusBar)

    } else {

            let statusBar = UIApplication.shared.value(forKeyPath: "statusBarWindow.statusBar") as? UIView
            statusBar?.backgroundColor = AppThemeColor

        }
    }
}

从键窗口中删除状态栏

func removeStatusBar(){

    if #available(iOS 13.0, *) {

        UIApplication.shared.keyWindow?.viewWithTag(100)?.removeFromSuperview()

    }
}

在viewDidLoad并viewWillAppear调用上面的函数

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

    removeStatusBar()
    statusBarColorChange()
}

override func viewDidLoad() {
    super.viewDidLoad()

    removeStatusBar()
    statusBarColorChange()

}

KeyWindow 在 iOS13 中已弃用。您可以将此扩展用于swift 5和iOS 13 到顶部

extension UIApplication {

    var statusBarUIView: UIView? {

        if #available(iOS 13.0, *) {
            let tag = 3848245

            let keyWindow: UIWindow? = UIApplication.shared.windows.filter {$0.isKeyWindow}.first

            if let statusBar = keyWindow?.viewWithTag(tag) {
                return statusBar
            } else {
                let height = keyWindow?.windowScene?.statusBarManager?.statusBarFrame ?? .zero
                let statusBarView = UIView(frame: height)
                statusBarView.tag = tag
                statusBarView.layer.zPosition = 999999

                keyWindow?.addSubview(statusBarView)
                return statusBarView
            }

        } else {

            if responds(to: Selector(("statusBar"))) {
                return value(forKey: "statusBar") as? UIView
            }
        }
        return nil
      }
}

并在AppDelegate类的didFinishLaunchingWithOptions中使用它，例如：

UIApplication.shared.statusBarUIView?.backgroundColor = .red(any color)

你可以试试这个

{
    UIView *_localStatusBar = [[UIApplication sharedApplication].keyWindow.windowScene.statusBarManager performSelector:@selector(createLocalStatusBar)];
    statusBar = [_localStatusBar performSelector:@selector(statusBar)];
}
else
{
    statusBar = [[UIApplication sharedApplication] valueForKey:@"statusBar"];

这是我见过的最好的答案.. 干杯

    if #available(iOS 13.0, *) {
    let app = UIApplication.shared
    let statusBarHeight: CGFloat = app.statusBarFrame.size.height

    let statusbarView = UIView()
        statusbarView.backgroundColor = ColorPalette.grayChateau  
    view.addSubview(statusbarView)

    statusbarView.translatesAutoresizingMaskIntoConstraints = false
    statusbarView.heightAnchor
        .constraint(equalToConstant: statusBarHeight).isActive = true
    statusbarView.widthAnchor
        .constraint(equalTo: view.widthAnchor, multiplier: 1.0).isActive = true
    statusbarView.topAnchor
        .constraint(equalTo: view.topAnchor).isActive = true
    statusbarView.centerXAnchor
        .constraint(equalTo: view.centerXAnchor).isActive = true

} else {
    let statusBar = UIApplication.shared.value(forKeyPath: "statusBarWindow.statusBar") as? UIView
    statusBar?.backgroundColor = UIColor.red

对于像我这样仍在使用它的人来说，这是投票最多的答案的 ObjC 版本：

创建一个 UIApplication 类别并将其添加到您的项目中：

@implementation UIApplication (iOS13PorcoDiDio)

- (UIView*) statusBar
{

    if([UIDevice getOSVersion] >= 13)
    {

        const NSUInteger k_TAG_STATUSBAR = 38482458385;

        UIView * vStatusBar = [[UIApplication sharedApplication].keyWindow viewWithTag:k_TAG_STATUSBAR];
        if(vStatusBar != nil)

            return vStatusBar;

        else {

            UIView *vStatusBar = [[UIView alloc] initWithFrame:[UIApplication sharedApplication].statusBarFrame];
            [vStatusBar setTag:k_TAG_STATUSBAR];
            [[UIApplication sharedApplication].keyWindow addSubview:vStatusBar];

            return vStatusBar;

        }

    } else if([UIApplication respondsToSelector:@selector(statusBar)])

        return (UIView*)[UIApplication sharedApplication].statusBar;

    else

        return nil;


}

Use this Extension:

extension UINavigationController {

func setStatusBar(backgroundColor: UIColor) {
    let statusBarFrame: CGRect
    if #available(iOS 13.0, *) {
        statusBarFrame = view.window?.windowScene?.statusBarManager?.statusBarFrame ?? CGRect.zero
    } else {
        statusBarFrame = UIApplication.shared.statusBarFrame
    }
    let statusBarView = UIView(frame: statusBarFrame)
    statusBarView.backgroundColor = backgroundColor
    view.addSubview(statusBarView)
