Hello,

It's about Xcode 8.3.2 and Swift 3 project.

I'm using UserNotifications, by adding UNUserNotificationCenterDelegate in my AppDelegate classes.

In order to recive the local notifications, I did these codes in my View Controller.swift :

          let yes = UNNotificationAction(identifier: "yes", title: "send SOS", options: .foreground)
          let no =  UNNotificationAction(identifier: "no", title: "ignore", options: .foreground)


          let category = UNNotificationCategory(identifier: "cat", actions: [yes, no], intentIdentifiers: [], options: [])
          UNUserNotificationCenter.current().setNotificationCategories([category])
          let content_2 = UNMutableNotificationContent()
          content_2.title = "You'r ok?!"
          content_2.body = "Alert!!"
          content_2.sound = UNNotificationSound.init(named: "SM.mp3")
          content_2.categoryIdentifier = "cat"
          let trigger_2 = UNTimeIntervalNotificationTrigger(timeInterval: 1, repeats: false)
          let request = UNNotificationRequest(identifier: "any", content: content_2, trigger: trigger_2)
          UNUserNotificationCenter.current().add(request, withCompletionHandler: nil)

And also these fonctions in my AppDelegate.swift :

UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge]) { (allowed, error) in
      }
        UNUserNotificationCenter.current().delegate = self
        return true
    }

  func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
        completionHandler([.alert, .badge, .sound])
    }

Until here, I can recive the local notifications. And work great.

Problem :

Normally when I am in View controller, I can open the sms interface window easily with these codes :

                let controller = MFMessageComposeViewController()
                controller.body = "SOS"
                controller.recipients = ["11111111111"]
                controller.messageComposeDelegate = self
                self.present(controller, animated: true, completion: nil)

and this function :

   func messageComposeViewController(_ controller: MFMessageComposeViewController, didFinishWith result: MessageComposeResult)
    {
      self.dismiss(animated: true, completion: nil)
    }

But here my UNNotificationResponse function is in AppDelegate class, and I want to apply 2 actions, in my AppDelegate.swift for these responses :

    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
        /

        if response.actionIdentifier == "yes"
        {
            print("Envoyer SOS")
  
  
  
        } else
        {
            print("oui ca va")
        }
    }

(Considering that I'll recive these notifications outside of my application, when it's suspending in background.)

1- To open user interface sms windows with selecting "yes" as response.actionIdentifier.

2 - To ignore the notification and rest outside of application by selecting "no" as response.actionIdentifier.

I tested some methods but always either an error or crash.
