No tap property on Background use case - iOS Ionic 4 app

[Sampath-Lokuge]

Hi,

There is no tap property on iOS device background use case. Hence it shows the notification 2 times. i.e. it always fires // Received in foreground section on fcmListeners() method. i.e. it shows system tray notification and custom notification where I have created for a foreground use case.

Note: Here I use firebase console dashboard to send the push. i.e. no API call

Note: No issues on the Killed use case. i.e. it doesn't fire the custom notification. only the system tray notification shows. This is the behavior where I need background use case too.

Note: No issues on Android device. i.e. it works fine on all 3 use cases.

service.ts

  async init() {
    if (this.platform.is('android')) {
      this.fcmToken = await this.firebase.getToken();
    } else if (this.platform.is('ios')) {
      const res = await this.firebase.hasPermission();
      if (!res.isEnabled) {
        await this.firebase.grantPermission();
        this.fcmToken = await this.firebase.getToken();
      }
    }
    this.fcmListeners();
    console.log('this.fcmToken', this.fcmToken);
  }

  fcmListeners() {
    this.firebase.onMessageReceived().subscribe(async (data: any) => {
      if (data.tap === 'background') {// when user tapped the background notification
        console.log('background notification', JSON.stringify(data, null, 4));
      } else { // Received in foreground
        console.log('Received in foreground', JSON.stringify(data, null, 4));
        this.showToastService.showFcmToast(data.title, data.message, data); // custom toast
      }
    });
  }

app.componet.ts

initializeApp() {
    this.platform.ready().then(() => {
      if (this.platform.is('cordova')) {
        this.firebaseCloudMessagingService.init(); // fcm
      }
    });
  }

I have exactly the same problem with Ionic4; there is no tap property for iOS. I've also set notification_foreground: 'true', but it doesn't show the native notification. In Android it works well.

Config:

"cordova": "^9.0.0",
"cordova-android": "8.0.0",
"cordova-ios": "5.0.1",
"cordova-plugin-firebasex": "6.0.6",

Hi !
I had the same problem. Looking at the logs I noticed that in the didReceiveRemoteNotification () method the TAP variable was not instantiated.

This piece of code must be added to the AppDelegate+FirebasePlugin.m file at line 150:

NSString* tap;
if([self.applicationInBackground isEqual:[NSNumber numberWithBool:YES]]){
    tap = @"background";
}else{
    tap = @"foreground";
    
}
[mutableUserInfo setValue:tap forKey:@"tap"];
if([mutableUserInfo objectForKey:@"messageType"] == nil){
    [mutableUserInfo setValue:@"notification" forKey:@"messageType"];
}

I can confirm the problem.

@papattes solution fixes the problem.

@papattes Can't you create a PR for your solution?

[papattes]

@Sampath-Lokuge I created it, however, it added it on the arnesson/cordova-plugin-firebase repo.
When I click that new PR, I am redirected automatically to this repository. How to do ?
