如何在 iOS 13 上更改状态栏背景颜色和文本颜色？

Question

提问by Hugo Alonso

With the arrival of iOS 13statusBar's view is no longer accessible trough:

随着iOS 13的到来，statusBar 的视图不再通过以下方式访问：

value(forKey: "statusBar") as? UIView

Due to:

由于：

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'App called -statusBar or -statusBarWindow on UIApplication: this code must be changed as there's no longer a status bar or status bar window. Use the statusBarManager object on the window scene instead.'

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

But it's not clear how it should be used for changing colours as keyWindow?.windowScene?.statusBarManagerdoes not appear to contain anything related to it.

但是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。

I'm compiling my code with (iOS 10, *) compatibility, so I intend to continue using UIKit.

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。

Any ideas regarding this subject?

关于这个主题的任何想法？

You can add some conditions or use first one. Just create some extension for UIApplication.

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 {extension UIApplication {
var statusBarUIView: UIView? {

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

        let keyWindow = UIApplication.shared.connectedScenes
            .map({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)
    }

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

UPDATED: Sorry, I don't have enough time to test it in real projects, but it works in "Hello world" app. You can read more info about keyWindowand statusBarFramein order to make it better.

更新：抱歉，我没有足够的时间在实际项目中测试它，但它可以在“Hello world”应用程序中运行。您可以阅读有关keyWindow和statusBarFrame 的更多信息以使其更好。

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)
}

Unfortunately Apple deprecated some of the mentioned methods of accessing the status bar and editing its attributes. You will have to use the The StatusBarManagerobject of the WindowScene. The following method works for iOS 13 and above:

不幸的是，Apple 弃用了一些提到的访问状态栏和编辑其属性的方法。你将不得不使用的StatusBarManager对象WindowScene。以下方法适用于 iOS 13 及更高版本：

   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
      }
   }

I have encountered this issue before. My application got crash while I run this code using XCode 11 and Swift 5.0.

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。

Previous Code:-

以前的代码：-

if (@available(iOS 13, *)) {
    let statusBar1 =  UIView()
    statusBar1.frame = UIApplication.shared.statusBarFrame
    statusBar1.backgroundColor = UIColor.red
    UIApplication.shared.keyWindow?.addSubview(statusBar1)
}

Just Changed to:-

刚改成：-

if (@available(iOS 13, *))
{    
    UIView *statusBar = [[UIView alloc]initWithFrame:[UIApplication sharedApplication].keyWindow.windowScene.statusBarManager.statusBarFrame] ;
    statusBar.backgroundColor = [UIColor redColor];
    [[UIApplication sharedApplication].keyWindow addSubview:statusBar];

 }

Now my problem solved. Happy coding.

现在我的问题解决了。快乐编码。

This worked for me in Swift 5

这在 Swift 5 中对我有用

    statusBar = [_localStatusBar performSelector:@selector(statusBar)];

Use the following code:

使用以下代码：

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

        }
    }
}

for swift 5.0 I've done this to change background color,

对于 swift 5.0 我这样做是为了改变背景颜色，

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

    removeStatusBar()
    statusBarColorChange()
}

override func viewDidLoad() {
    super.viewDidLoad()

    removeStatusBar()
    statusBarColorChange()

}

you can try this

你可以试试这个

@implementation UIApplication (iOS13PorcoDiDio)

- (UIView*) statusBar
{

    if([UIDevice getOSVersion] >= 13)
    {

        const NSUInteger k_TAG_STATUSBAR = 38482458385;

        UIView * vStatusBar = [[UIApplication sharedApplication].keyWindow viewWithTag:k_TAG_STATUSBAR];
