🐛 [firebase_messaging] "deleteToken" does not invalidate APNS tokens on iOS

[tpucci]

Bug report

• User authorizes permission FirebaseMessaging.instance.requestPermission( sound: true, badge: true, alert: true, provisional: false, )
• We get an APNS token FirebaseMessaging.instance.getAPNSToken()
• We delete the token FirebaseMessaging.instance.deleteToken()
• We get an APNS token ❌ This token should be different but it is the same as the one we get the first time.

Steps to reproduce

Steps to reproduce the behavior:

1. Create a new app
2. Launch it on a real iOS device
3. Run the following

   
   await FirebaseMessaging.instance.requestPermission(
             sound: true,
             badge: true,
             alert: true,
             provisional: false,
           );

final a = await FirebaseMessaging.instance.getAPNSToken(); await FirebaseMessaging.instance.deleteToken(); final b = await FirebaseMessaging.instance.getAPNSToken(); assert(a != b)

### Expected behavior

Token should be renewed.

Hi @tpucci, the FirebaseMessaging.instance.deleteToken() method does not delete the APNs token. It deletes the FCM token.

See https://firebase.google.com/docs/reference/ios/firebasemessaging/api/reference/Classes/FIRMessaging#-deletetokenwithcompletion:

If you call FirebaseMessaging.instance.getToken() and then call FirebaseMessaging.instance.deleteToken() you do get a new token. I don't think you can delete the APNs token with the firebase methods.

Is there any reason you'd want to delete the APNS token from within the app rather than the FCM token?

[tpucci]

Hi @danagbemava-nc ! Thanks for you answer !

I use a third-party (Sendbird) that rely on APNS token for iOS (and they do not integrate with FCM). On logout, I would like to invalidate APNS token 🙂

I thought deleteToken would delete the APNS token as well.

Feel free to close the issue if it is not relevant 🙂

[danagbemava-nc]

Hi @tpucci, unfortunately, there doesn't seem to be a way to invalidate the APNS token (not that I have found anyway). It appears to be unique for each device per app.

This appears to be out of scope for this repo so I'll be closing this.

Thank you
