iOS13 设置状态栏背景颜色

Question

我以前有下面的代码，但在升级到 iOS 13 后，我得到以下错误：

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

应用在 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 window。请改用 window 场景中的 statusBarManager 对象。'

现在怎么设置状态栏的背景色？

警告消息提到了使用 statusBarManager，所以我做了类似的事情，但我无法让它工作。

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)
    }

Kuray 刚刚在这里为我提供了一个解决方案：

将以下内容添加到 viewdidload。请前往他的媒介 post 并为他鼓掌！

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：

向 UIViewController 扩展添加了“statusBarColorChange()”。

func statusBarColorChange() {

if #available(iOS 13.0, *) {

    let statusBar = UIView(frame: UIApplication.shared.windows.filter {[=10=].isKeyWindow}.first?.windowScene?.statusBarManager?.statusBarFrame ?? CGRect.zero)
    statusBar.backgroundColor = .appThemeButtonsColor
        statusBar.tag = 100
    UIApplication.shared.windows.filter {[=10=].isKeyWindow}.first?.addSubview(statusBar)

} else {

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

    }
}

希望能有所帮助:)

对于 statusBarFrame 弃用警告，更新了 Daryl Wong 接受的答案：

 let window = UIApplication.shared.windows.filter {[=10=].isKeyWindow}.first
 guard let statusBarHeight = window?.windowScene?.statusBarManager?.statusBarFrame.size.height else { return }
 let statusbarView = UIView(frame: CGRect(x: 0,
                                          y: 0,
                                          width: UIScreen.main.bounds.size.width,
                                          height: statusBarHeight))
 statusbarView.backgroundColor = UIColor.red
 view.addSubview(statusbarView)
