Error to get location after push notification iOS 9 - ios

Question

After receive a push notification I am trying to get the current localization.
However when I start the code bellow the corelocation fails (didFailWithError) when the app is at background :(
Only works in foreground.
Why?
I already did the .plist for background configuration
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(nonnull NSDictionary *)userInfo fetchCompletionHandler:(nonnull void (^)(UIBackgroundFetchResult))completionHandler{
__block UIBackgroundTaskIdentifier bgTask = [application beginBackgroundTaskWithExpirationHandler:^{
[application endBackgroundTask:bgTask];
bgTask = UIBackgroundTaskInvalid;
NSLog(#" Finalizado background...");
}];
[self handleStartMonitoringLocation];
NSLog(#"Main Thread proceeding...");
}
-(void)handleStartMonitoringLocation{
// location
if (!self.shareModel) {
self.shareModel = [LocationManager sharedManager];
self.shareModel.afterResume = NO;
[self.shareModel addApplicationStatusToPList:#"didFinishLaunchingWithOptions"];
}
[self.shareModel addApplicationStatusToPList:#"applicationDidBecomeActive"];
//Remove the "afterResume" Flag after the app is active again.
self.shareModel.afterResume = NO;
// [self.shareModel startMonitoringLocation];
[self.shareModel startBackgroundLocationUpdates];
}
-(void)startBackgroundLocationUpdates {
// Create a location manager object
self.anotherLocationManager = [[CLLocationManager alloc] init];
// Set the delegate
self.anotherLocationManager.delegate = self;
// Request location authorization
[self.anotherLocationManager requestWhenInUseAuthorization];
// Set an accuracy level. The higher, the better for energy.
self.anotherLocationManager.desiredAccuracy = kCLLocationAccuracyBest;
// Enable automatic pausing
self.anotherLocationManager.pausesLocationUpdatesAutomatically = YES;
// Specify the type of activity your app is currently performing
self.anotherLocationManager.activityType = CLActivityTypeFitness;
if(SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(#"9.0")){
// Enable background location updates
self.anotherLocationManager.allowsBackgroundLocationUpdates = YES;
[self.anotherLocationManager requestLocation];
}
else{
// Start location updates
[self.anotherLocationManager startUpdatingLocation];
}
}
