I am implementing notifications in my app and I can not figure out how to go to a specific view controller when the user presses on the notification. Since iOS 13, my app is using SceneDelegate, but the function: userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) only gets called on in the AppDelegate.
How can I go to a specific view controller when the user taps on the notification when my app uses SceneDelegate? All the resources I found online dealt with iOS 12 or lower versions where you choose the view controller from AppDelegate.
There are several ways one simple way is to do post notification through NotficationCeneter.
NotificationCenter.default.post(name: Notification.Name("SOME_NAME"), object: nil, userInfo: nil)
And you should add an observer for this notification.
NotificationCenter.default.addObserver(self, selector: #selector(someMethod(notification: )), name: Notification.Name("SOME_NAME"), object: nil)
There are also different options
For example, I create a simple Navigator class which is Singleton and who keeps the top NavigationController and all the knowledge about the current stack of views. And if I need to open some specific screen from the AppDelegate, I'm using something like:
MyNavigator.shared.goToSomeScreen()
Still, everything depends on what is your current code and what is your need, for sure you can find something that fits better for you.
