How to detect if user has taken action local notification or remote notification?

Question

I am displaying local and remote notifications in my app. Now there is scenario if the notification is local then I want to take a different action or if the the notification is remote then I want to take some different action.

Till iOS 9 I was using below code to detect if the notification is local or remote.

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {


    if launchOptions?[UIApplicationLaunchOptionsKey.localNotification] != nil {
        // Do what you want to happen when a remote notification is tapped.
    }
    return true
  }

But in iOS 10 this approach is deprecated so now how do I make sure the notification is local or remote ?

For iOS 10 and above using UserNotifications framework.

To check user has taken an action on a notification. You can conform to UNUserNotificationCenterDelegate and implement userNotificationCenter:didReceiveNotificationResponse:withCompletionHandler:

To check if it is a remote notification. You can check type of trigger, since remote notifications trigger is UNPushNotificationTrigger.

Here's the code...

#pragma mark - UNUserNotificationCenterDelegate

- (void)userNotificationCenter:(UNUserNotificationCenter *)center
didReceiveNotificationResponse:(UNNotificationResponse *)response
         withCompletionHandler:(void (^)(void))completionHandler {

    if ([response.notification.request.trigger isKindOfClass:[UNPushNotificationTrigger class]]) {
        // User did tap at remote notification
    }

    completionHandler();
}

In UNMutableNotificationContent add userInfo in like below:

content.userInfo = ["isLocalNotification" : true]

Now in AppDelegate set UNUserNotificationCenterDelegate in didFinishLaunchingWithOptions like below:

UNUserNotificationCenter.current().delegate = self

Then implement didReceive response method of UNUserNotificationCenterDelegate:

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

        print(response.notification.request.content.userInfo)
    }

in output you will get something like below:

[AnyHashable("isLocalNotification"): 1]

you can identify Local Notification with isLocalNotification key.

You can refer below link. You will get your answer. If not please let me know:

Further information regarding Notification category:

To identify local and remote notification you can assign an identifier to notification object. UIMutableUserNotificationCategory is deprecated in iOS 10, So use UNNotificationCategory to assign identifier to notification.

Refer below links for assigning an identifier to notification :
