以前

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

现在

if #available(iOS 13.0, *) {
            let statusBar = UIView(frame: UIApplication.shared.keyWindow?.windowScene?.statusBarManager?.statusBarFrame ?? CGRect.zero)
            if statusBar.responds(to:#selector(setter: UIView.backgroundColor)) {
                statusBar.backgroundColor = color
            }
            UIApplication.shared.keyWindow?.addSubview(statusBar)
        } else {
            let statusBar: UIView = UIApplication.shared.value(forKey: "statusBar") as! UIView
            if statusBar.responds(to:#selector(setter: UIView.backgroundColor)) {
                statusBar.backgroundColor = color
            }
        }
