Question

我曾经有以下代码，但是升级到iOS 13之后，出现以下错误：

UIApplication.shared.statusBarView?.backgroundColor = UIColor(red: 94/225, green: 64/255, blue:204/255, alpha: 1.0)

在UIApplication上名为-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。而是在窗口场景上使用statusBarManager对象。'

现在如何设置状态栏的背景色？

警告消息中提到了有关使用statusBarManager的信息，所以我做了类似的事情，但我无法使其正常工作。

var statusBar = UIView()

    if #available(iOS 13.0, *) {
        statusBar = UIView(frame: UIApplication.shared.keyWindow?.windowScene?.statusBarManager?.statusBarFrame ?? CGRect.zero)
        statusBar.backgroundColor = UIColor.red
        UIApplication.shared.keyWindow?.addSubview(statusBar)
    } else {
        //ios 12 and below
        UIApplication.shared.statusBarView?.backgroundColor = UIColor(red: 94/225, green: 64/255, blue:204/255, alpha: 1.0)
    }

库拉（Kuray）在这里为我提供了一个解决方案：

将以下内容添加到viewdidload。请转到他的中级职位，并给他一些鼓掌！

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

        let statusbarView = UIView(frame: CGRect(x: 0, y: 0, width: UIScreen.main.bounds.size.width, height: statusBarHeight))
        statusbarView.backgroundColor = UIColor.red
        view.addSubview(statusbarView)
    } else {
        let statusBar = UIApplication.shared.value(forKeyPath: "statusBarWindow.statusBar") as? UIView
        statusBar?.backgroundColor = UIColor.red
    }

代码适用于 Swift 5+ 和 iOS 13+

请参考答案：https://stackoverflow.com/a/64924164/7610245

在 UIViewController 扩展中添加了“statusBarColorChange()”。

func statusBarColorChange() {

if #available(iOS 13.0, *) {

    let statusBar = UIView(frame: UIApplication.shared.windows.filter {$0.isKeyWindow}.first?.windowScene?.statusBarManager?.statusBarFrame ?? CGRect.zero)
    statusBar.backgroundColor = .appThemeButtonsColor
        statusBar.tag = 100
    UIApplication.shared.windows.filter {$0.isKeyWindow}.first?.addSubview(statusBar)

} else {

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

    }
}

希望会有所帮助:)
