UIView没有覆盖状态栏区域

Question

我正在以编程方式创建一个汉堡包菜单。

我试图让侧面菜单（灰色UIView）覆盖状态栏区域，当它滑出时，UIView具有与屏幕大小相关的约束。

我在手势开始时隐藏状态栏alpha但由于某种原因，状态栏的背景仍为纯白色。见下面的例子：

是否有可能将UIView覆盖在这个区域？

侧栏的代码：

let screenHeight = UIScreen.main.bounds.height
let screenWidth = UIScreen.main.bounds.width

var sideBarUIView: UIView! = {
        let sideBarUIView = UIView()
        sideBarUIView.backgroundColor = UIColor(red:1.0, green:1.0, blue:0.21, alpha:0.0)
        sideBarUIView.translatesAutoresizingMaskIntoConstraints = false
        return sideBarUIView
    }()

 override func viewDidLoad() {
        super.viewDidLoad()

        view.addSubview(sideBarUIView)
}

        sideBarUIView.centerYAnchor.constraint(equalTo: view.centerYAnchor).isActive = true
        sideBarUIView.heightAnchor.constraint(equalToConstant: screenHeight).isActive = true
        sideBarUIView.widthAnchor.constraint(equalToConstant: screenWidth).isActive = true

我正在使用此行隐藏状态栏：

self.statusBarWindow?.alpha = 0.0

你可以试试这个

class ViewController: UIViewController {

    let screenHeight = UIScreen.main.bounds.height
    let screenWidth = UIScreen.main.bounds.width

    lazy var sideBarUIView: UIView! = {
        let sideBarUIView = UIView()
        sideBarUIView.backgroundColor = UIColor.red
        sideBarUIView.translatesAutoresizingMaskIntoConstraints = false
        return sideBarUIView
    }()

    override func viewDidLoad() {
        super.viewDidLoad()

        view.addSubview(sideBarUIView)

        sideBarUIView.leadingAnchor.constraint(equalTo: view.leadingAnchor).isActive = true
        sideBarUIView.heightAnchor.constraint(equalToConstant: screenHeight).isActive = true
        sideBarUIView.widthAnchor.constraint(equalTo: self.view.widthAnchor, multiplier: 0.5).isActive = true
        sideBarUIView.topAnchor.constraint(equalTo: view.topAnchor).isActive = true


    }

}
