I'm trying to have a push notification take the user to a specific view controller when pressed on it.
I currently have this in my AppDelegate:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge]) { granted, error in
if let error = error {
print(error.localizedDescription)
} else {
application.registerForRemoteNotifications()
}
}
UNUserNotificationCenter.current().delegate = self
return true
}
When I press on the notification and open the app from the background, none of these are being called:
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
completionHandler([.alert, .sound, .badge])
}
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
}
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
}
if your app is not running in the background you will handle notification in didFinishLaunchingWithOptions like this
let notificationInfo = launchOptions?[UIApplication.LaunchOptionsKey.remoteNotification] as? [String : Any]
and if your app is running in background/foreground you will handle notification tap in
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void)
