Estoy creando una aplicación que comprueba si el usuario está cerca de una tienda de mi cliente, si lo hace, le envía una notificación.

Quiero que la aplicación también lo verifique en segundo plano.

He agregado estas líneas a miinfo.plist archivo:

y aquí está mi código:

AppDelegate.m:

-(BOOL)application:(UIApplication *)application willFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[self configureLocationManager];
[self.locationManager startUpdatingLocation];

return YES;
}
-(void)configureLocationManager
{
    //Initializing locationManager
    self.locationManager=[[CLLocationManager alloc] init];
    //setting "locationManager"'s(CLLocationManager) delegate to "self"
    self.locationManager.delegate=self.monitorLocationVC;
    //Setting "locationManager"'s(CLLocationManager)'s distance filter to none
    //self.locationManager.distanceFilter=kCLDistanceFilterNone;
    //Setting "locationManager"'s(CLLocationManager)'s activityType to navigation
    self.locationManager.activityType=CLActivityTypeAutomotiveNavigation;
    //setting "locationManager"'s(CLLocationManager) desiredAccuracy to "best"
    self.locationManager.desiredAccuracy=kCLLocationAccuracyBestForNavigation;
    //If OS version is 9 or above - setting "allowsBackgroundLocationUpdates" to YES
    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 9) {
        self.locationManager.allowsBackgroundLocationUpdates = YES;
    }
}

MonitorLocationViewController.m:

-(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray<CLLocation *> *)locations
{
    [self checkIfNearStore]; //Not being called in background
}

-(void)checkIfNearStore
{
    for (Store *currentStore in self.allStores) {
        if ([currentStore.circularRegion containsCoordinate:self.locationManager.location.coordinate]&&currentStore.alreadySendNotification==NO) {
            NSLog(@"Entered: %@",[[self storeForRegion:currentStore.circularRegion] address]);
            currentStore.alreadySendNotification=YES;
            [self.storesAlreadySentNotifications addObject:currentStore];
        }
    }

    for (Store *currentStore in self.storesAlreadySentNotifications) {
        if (![currentStore.circularRegion containsCoordinate:self.locationManager.location.coordinate]) {
            currentStore.alreadySendNotification=NO;
        }
    }
}

Alguien tiene una idea? ¡Gracias!
