plugin doesn't let cordova-plugin-fcm-with-dependecy-updated ^2.4.0 plugin handle notification

Your Environment

• Plugin version: 3.0.3
• Platform: iOS
• OS version: 11.0.3 and 12.3.1
• Device manufacturer and model: iPhone 6, iPhone 6s

• Running in Simulator: no
• Cordova version (cordova -v): 8.1.2
• Cordova platform version (cordova platform ls): ios 4.5.4
• Plugin configuration options:

geolocation.configure({
            locationProvider: _geolocation.ACTIVITY_PROVIDER,
            desiredAccuracy: _geolocation.MEDIUM_ACCURACY,
            stationaryRadius: 0,
            distanceFilter: 0,
            debug: false,
            stopOnTerminate: true,
            stopOnStillActivity: false,
            startForeground: true,
            fastestInterval: 10000,
            interval: 10000,
            maxLocations: 1
        }

Context

in CDVBackgroundGeolocation.m file debugger never goes into if statement

- (void)userNotificationCenter:(UNUserNotificationCenter *)center
       willPresentNotification:(UNNotification *)notification
         withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler
{
    if (prevNotificationDelegate && [prevNotificationDelegate respondsToSelector:@selector(userNotificationCenter:willPresentNotification:withCompletionHandler:)])
    {
        // Give other delegates (like FCM) the chance to process this notification

        [prevNotificationDelegate userNotificationCenter:center willPresentNotification:notification withCompletionHandler:^(UNNotificationPresentationOptions options) {
            completionHandler(UNNotificationPresentationOptionAlert);
        }];
    }
    else
    {
        completionHandler(UNNotificationPresentationOptionAlert);
    }
}

Expected Behavior

plugin should let others handle push data (in my case fcm, which works properly without this plugin)

Actual Behavior

debugger always choses else statement and only displays notification in upper banner, no matter if app is foreground

Steps to Reproduce

1. clear project
2. cordova plugin add cordova-plugin-fcm-with-dependecy-updated@^2.4.0
3. cordova plugin add @mauron85/cordova-plugin-background-geolocation@3.0.3
4. put breakpoint on line 484 in CDVBackgroundGeolocation.m
5. send any test push from firebase console

@ProximaHaiz just in case you haven’t fix this issue yet, I solved it from my side by commenting these lines in plugins/cordova-plugin-mauron85-background-geolocation/CDVBackgroundGeolocation.m

    // [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(onAppPause:) name:UIApplicationDidEnterBackgroundNotification object:nil];
    // [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(onAppResume:) name:UIApplicationWillEnterForegroundNotification object:nil];
    // [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(onFinishLaunching:) name:UIApplicationDidFinishLaunchingNotification object:nil];
    // [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(onAppTerminate:) name:UIApplicationWillTerminateNotification object:nil];

After that Push Notifications worked as expected.

Hope this helps.

@nuno @ProximaHaiz @walfridosp @dzziwny @mauron85 I have a PR that fixes the issue https://github.com/mauron85/cordova-plugin-background-geolocation/pull/696

The problem is that it’s overriding the notification center delegate. It should only override it when it is in debugging mode. There is no need to comment out the addObserver lines
