Send tag to OneSignal after log in

Question

I want to send tag to a specific user after he/she logged in so he/she can receive notifications. Only logged in users will receive notifications. When he/she logs out, I will delete his/her tag. How can I do this?

My code in AppDelegate:

let oneSignal: OneSignal = OneSignal(launchOptions: launchOptions, appId: "<my-app-id>") {
        (message, additionalData, isActive) in

        if (additionalData != nil) {
            NSLog("APP LOG ADDITIONALDATA: %@", additionalData);
            let displayMessage: NSString = NSString(format:"NotificationMessage:%@", message);

            var messageTitle: NSString = "";
            if (additionalData["discount"] != nil) {
                messageTitle = additionalData["discount"] as String
            }
            else if (additionalData["bonusCredits"] != nil) {
                messageTitle = additionalData["bonusCredits"] as String;
            }
            else if (additionalData["actionSelected"] != nil) {
                messageTitle = NSString(format:"Pressed ButtonId:%@", additionalData["actionSelected"] as String);
            }

            var alertView: UIAlertView = UIAlertView(title: messageTitle,
                message:displayMessage,
                delegate:self,
                cancelButtonTitle:"Close");

            alertView.show();
        }

        else if (isActive) {
            var alertView: UIAlertView = UIAlertView(title:"OneSignal Message",
                message:message,
                delegate:self,
                cancelButtonTitle:"Close");
            alertView.show();
        }
    }

My code in my LogInViewController:

let oneSignal = OneSignal()
oneSignal.sendTag("username", value: self.usernameTextField.text)

The code in my appDelegate is working fine, my users already receive notifications. But they can receive notifications even if they're not logged in.

Objective-C:

// Send tag: After login 
[OneSignal sendTag:@"key" value:@"value"];      

// Delete tag: After logout
[OneSignal deleteTag:@"key"];

Swift:

// Send tag: After login
OneSignal.sendTag("key", value: "value") // for sending that is inserting tag in OneSignal

// Delete tag: After logout
OneSignal.deleteTag("key")  // delete that specific tag from OneSignal db
