I have some code that presents an alert to the user with information they need,
and an OK button to clear it. It works fine in the previous Xcode versions.
However, after upgrading to 11, it now displays the alert and then immediately
clears it. This happens both in the simulator and on a real device. I have
played around with the code and can't figure out how to make it leave the alert
on the screen. This is in Swift. It is a function that is called from
numerous places in the app.
func NotificationAlert (_ msg1: String, _ msg2: String) {
let ErrorAlert = UIAlertController(title: msg1, message: msg2,
preferredStyle: .alert)
let dismiss = UIAlertAction(title: "Ok", style: .default, handler: nil)
ErrorAlert.addAction(dismiss)
ErrorAlert.presentInOwnWindow(animated: true, completion: nil)
}
extension UIAlertController {
func presentInOwnWindow(animated: Bool, completion: (() -> Void)?) {
let alertWindow = UIWindow(frame: UIScreen.main.bounds)
alertWindow.rootViewController = UIViewController()
alertWindow.windowLevel = UIWindow.Level.alert + 1;
alertWindow.makeKeyAndVisible()
alertWindow.rootViewController?.present(self, animated: animated,
completion: completion)
}
}
