Question

在Xcode 10和Swift 5的早期版本中，我曾经按如下方式更改状态栏的颜色：-

if let statusBar = UIApplication.shared.value(forKey: "statusBar") as? UIView {
   if statusBar.responds(to: #selector(setter: UIView.backgroundColor)) {
      statusBar.backgroundColor = #colorLiteral(red: 0, green: 0.7156304717, blue: 0.9302947521, alpha: 1)
   }
}

现在在Xcode 11和Swift 5.1上出现以下错误：-

由于未捕获的异常“ NSInternalInconsistencyException”而终止应用程序，原因：“ UIApplication上的名为-statusBar或-statusBarWindow的应用程序：由于不再有状态栏或状态栏窗口，因此必须更改此代码。而是在窗口场景上使用statusBarManager对象。'

有什么建议吗？

尝试一下：

extension UIApplication {


class var statusBarBackgroundColor: UIColor? {
    get {
        return statusBarUIView?.backgroundColor
    } set {
        statusBarUIView?.backgroundColor = newValue
    }
}

class var statusBarUIView: UIView? {
    if #available(iOS 13.0, *) {
        let tag = 987654321

        if let statusBar = UIApplication.shared.keyWindow?.viewWithTag(tag) {
            return statusBar
        }
        else {
            let statusBarView = UIView(frame: UIApplication.shared.statusBarFrame)
            statusBarView.tag = tag

            UIApplication.shared.keyWindow?.addSubview(statusBarView)
            return statusBarView
        }
    } else {
        if responds(to: Selector(("statusBar"))) {
            return value(forKey: "statusBar") as? UIView
        }
    }
    return nil
}}

使用UIStatusBarManager
