docs: onNotificationOpenedApp & getInitialNotification not supported on IOS

[arjendevos]

React.useEffect(() => {
    requestUserPermission().then(() => {
      messaging()
        .getToken()
        .then((token) => {
          console.log("FCM Token:", token);
        });
    });

    messaging().onNotificationOpenedApp((remoteMessage) => {
      Alert.alert("Notification caused app to open from background state:", JSON.stringify(remoteMessage));
    });

    messaging()
      .getInitialNotification()
      .then((remoteMessage) => {
        if (remoteMessage) {
          Alert.alert("Notification caused app to open from quit state:", JSON.stringify(remoteMessage));
        }
      });

    const unsubscribe = messaging().onMessage(async (remoteMessage) => {
      Alert.alert("A new FCM message arrived!", JSON.stringify(remoteMessage));
    });

    return unsubscribe;
  }, []);

Before i installed notifee, it worked fine. Now it only fires the onMessage() function.

Found the answer:
onNotificationOpenedApp and getInitialNotification from RNFB Messaging will no longer trigger as notifee will handle the event. Should not require any code changes to these RNFB event handlers, as events on Android will continue to work as normal

[arjendevos]

Can't find the alternative though

[helenaford]

ah yes, that's correct for iOS! Did you solve your issue?

[arjendevos]

@helenaford no, can't find the alternatives

[helenaford]

sorry, could you elaborate? what do you mean by alternatives?

[arjendevos]

@helenaford i need those 2 functions for both IOS and Android. If Notifee handles this now, how can i still use those 2 functions with Notifee?

[helenaford]

@arjendevos for iOS and for android when notifications are displayed when the app is open, you need to use notifee event handlers

[arjendevos]

@helenaford yeah i understand, but what can i use for when the app is closed?

[MustagheesButt]

@arjendevos From the Android Handling Interaction docs it says onForegroundEvent. And on iOS Handling Interaction docs, it says onBackgroundEvent.

I tried with both (on Android only), and it seems onBackgroundEvent is the alternate for both onNotificationOpenedApp and getInitialNotification. The following is in my index.js, and gets called when I click on the notification (app in background or killed state):

notifee.onBackgroundEvent(async ({ type, detail }) => {
  if (type === EventType.PRESS) {
    console.log("App opened from click");
  }
});

You should also check Notifee's getInitialNotification in App Open Events

@helenaford when pressing on a remote notification on IOS when the app in in background but not killed, it triggers onForegroundEvent instead of onBackgroundEvent, what is the status of this issue ? Thanks

[Avishayy]

@AnisDerbel Looks like this is intentional? See https://notifee.app/react-native/docs/events#app-open-events

getInitialNotification is deprecated on iOS in favour of the PRESS event received by the onForegroundEvent event handler

Meaning onForegroundEvent() is to be used to get the notification that opens the app, not onBackgroundEvent()

[AnisDerbel]

@Avishayy you are right,That's what I did. I use onForegroundEvent for both app in background or killed for IOS and getInitialNotification (from react-native-firebase/messaging) for Android when app is killed and onNotificationOpenedApp (from react-native-firebase/messaging) when app is in background.

All is good
