iOS: OnTokenRefresh will NEVER fire if autoRegistration=false

See original GitHub issue

Hi there,

great plugin, thanks.

Quick question.

I assume that OnTokenRefresh Event:

CrossFirebasePushNotification.Current.OnTokenRefresh += (s,p) => { System.Diagnostics.Debug.WriteLine($"TOKEN : {p.Token}"); };

Is only called when the token gets refreshed and NOT when the app is launched / token is initially generated?

Would the correct method be to check for and save the initial token on app launch using CrossFirebasePushNotification.Current.Token

In the RegisteredForRemoteNotifications override of AppDeligate on iOS?

Hi @rdelrosario - I’ve done some further investigation, and have found the issue.

Using plugin 3.1.6 on iOS 13.4 does NOT call OnTokenRefresh if the plugin is initialised as:

FirebasePushNotificationManager.Initialize(options, autoRegistration: false); Even if at a later date you call CrossFirebasePushNotification.Current.RegisterForPushNotifications(); - OnTokenRefresh will still never be invoked.

However if you initialise the plug in as: FirebasePushNotificationManager.Initialize(options);

The whole plugin works as expected on iOS and OnTokenRefresh is called as expected.

So the bug is with the autoRegistration argument on iOS being set to false.

Hope this helps.

So on further investigation, it appears that OnTokenRefresh event is called on Android after initially registering for notifications, but is NOT called on iOS after initially registering for notifications.

Therefore I am assuming that on iOS the correct procedure is to update the token to the remote server in RegisteredForRemoteNotifications and OnTokenRefresh

Would be greatful is someone else could confirm this behaviour? Thanks
