[iOS] onBackgroundEvent EventType Press, Dismissed or Delivered doesn't work

[shonie2xx]

The onBackgroundEvent works on Android, but not on iOS. The only event type that works for iOS is 7 (TRIGGER_NOTIFICATION_CREATED). Here is how I've implemented it:

const scheduleNotification = async (notificationTimestamp: number) => {
  // Request permissions (required for iOS)
  await notifee.requestPermission();

  // Android 12 limitations
  if (Platform.OS === 'android' && Platform.Version <= 12) {
    const settings = await notifee.getNotificationSettings();
    if (settings.android.alarm !== AndroidNotificationSetting.ENABLED) {
      await notifee.openAlarmPermissionSettings();
    }
  }

  // Create a channel (required for Android)
  const channelId = await notifee.createChannel({
    id: 'reminderId',
    name: 'Reminder',
    vibration: true,
    visibility: AndroidVisibility.PUBLIC,
    importance: AndroidImportance.HIGH,
  });

  // Create a time-based trigger
  const trigger: TimestampTrigger = {
    type: TriggerType.TIMESTAMP,
    timestamp: notificationTimestamp,
  };

  try {
    // Create a trigger notification
    await notifee.createTriggerNotification(
      {
        title: 'Title',
        body: 'Body!',
        android: {
          channelId,
          pressAction: {
            id: 'default',
          },
        },
      },
      trigger,
    );
  } catch (error) {
   recordError(error)
  }
};

In App.tsx I'm expecting the user action this way:

notifee.onBackgroundEvent(async ({ type, detail }) => {

  if (type === EventType.PRESS) {
    console.log('pressed');
  }
  if (type === EventType.DISMISSED) {
    console.log('dismissed');
  }
  if (type === EventType.DELIVERED) {
    console.log('delivered');
  }
});

Please help!

On [Android], the "press" event type also does not trigger when the phone is locked.

Any solution here?

check #616 (comment). looks like onBackgroundEvent is not like what we think about. use onForegroundEvent.

On [Android], the "press" event type also does not trigger when the phone is locked.

check #621 (comment). It's mostly like reactContext is null.

@Eclipses-Saros Thank you for your response. Using foregroundEvent does not resolve my issue. I still can't capture the event type on iOS. Could you provide more explanation on how to achieve this?

I'm also a bit confused by the documentation. It suggests using onForegroundEvent to handle cases where the user interacts with a notification, but that only applies when the app is in the foreground (visible). In my case, the app is either in the background or the phone is locked. When the user clicks the notification, the app opens, and from what I understand, I need to use onBackgroundEvent to handle the user's actions (events).

first of all, reactContext is null problem is related to Android. (didn't experienced same bug when iOS)

the app is either in the background or the phone is locked. When the user clicks the notification, the app opens, and from what I understand, I need to use onBackgroundEvent to handle the user's actions (events).

you mean, "the documentation says using onForegroundEvent to catch events, but foreground means app is in the foreground, not background"? yes you're right, but ironically notifee doesn't work what you think of.

NotifeeApiModule.m

- (void)sendNotifeeCoreEvent:(NSDictionary *_Nonnull)eventBody {
  dispatch_after(
      dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
        if (RCTRunningInAppExtension() ||
            [UIApplication sharedApplication].applicationState == UIApplicationStateBackground) {
          [self sendEventWithName:kReactNativeNotifeeNotificationBackgroundEvent body:eventBody];
        } else {
          [self sendEventWithName:kReactNativeNotifeeNotificationEvent body:eventBody];
        }
      });
}

here is some code from notifee iOS native module code. when you press notification, native module call sendNotifeeCoreEvent, check whether app status and send event.
put it simply: this code functions as determine app is foreground or not.
there's no more state check function.

in theory, press notification in the background or dead should be recognize as 'background' event... but sadly pressing notification makes app status into foreground, then called native function. that's the why onForegroundEvent function call.

+ however, if you meaning "I can't receive any press events from notification", there are another problems that I didn't know. in that case, I also need investigate this issue further more.

@Eclipses-Saros thanks for detailed explanation, now I understand. However, my issue is that I'm not receiving any notification press events at all [on iOS, android is working just fine]. Even when the app transitions from background to the foreground, the event doesn't seem to trigger.

Do you have any thoughts on what could be causing this?
I've also assumed that notifee can maybe interfere with other services like react-native-marketingcloudsdk or react-native-firebase/messaging, but that doesn't seem to be the issue.
