My Code works well in ios 12, but it works like the picture.
Also, I tried this code, it makes no difference
fileprivate lazy var netTipWindow:UIWindow = {
let window = UIWindow(frame: CGRect(x: 0, y: topMargins, width: UIScreenW, height: realheight))
window.backgroundColor = .clear
window.windowLevel = .alert
window.isHidden = false
if #available(iOS 13, *) {
window.addSubview(self)
} else {
window.rootViewController = UIViewController()
window.rootViewController?.view.addSubview(self)
}
frame = CGRect(x: 0, y: -(topMargins + realheight), width: UIScreenW, height: realheight)
return window
}()
