How to handle localNotifications when app is closed - ios

Question

I've searched in all questions here but no solution worked.
I scheduled localNotifications with a userInfo option.
When app is in foreground, the notification arrived and a can handle perfectly with this function that system calls by itself.
For local notifications
func application(_ application: UIApplication, didReceive notification: UILocalNotification) {
if application.applicationState == .active {
return
}
//My implementation
}
For remote notifications
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any]) {
if application.applicationState == .active {
return
}
//My implementation
}
But the problem is, when app is closed, this functions are not called and I can't handle the data that I need.
I've tried get userInfo in that function in appDelegate:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
if let localUserInfo = launchOptions?[UIApplicationLaunchOptionsKey.localNotification] as? [AnyHashable: Any] {
// My implementation
} else if let remoteUserInfo = launchOptions?[UIApplicationLaunchOptionsKey.remoteNotification] as? [AnyHashable: Any] {
// My implementation
}
return true
}
But.. Didn't work...
Someone could help me please?
Thanks in advance.

Answer 1

Have you registered for notifications?
In didFinishLaunchingWithOptions():
// Register Notifications
UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge], completionHandler: { granted, error in
if granted {
print("User notifications are allowed")
} else {
print("User notifications are NOT allowed")
}
})
application.registerForRemoteNotification()
UNUserNotificationCenter.current().delegate = self
Then you should catch local notifications in UNUserNotificationCenterDelegate method:
extension AppDelegate: UNUserNotificationCenterDelegate {
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: #escaping () -> Void) {
completionHandler()
}
}

You will get the notification in didFinishLaunchingWithOptions if the user clicks it whether it's local or remote , otherwise you won't know except if store them in server and pull them every time you open the app
