Change the options in location services

In Location Services, my app has three options: Never, While Using and Always. Is there any possibility of changing these options like removing the While Using option? Edit1: - (void)checkAuth { if ([[UIDevice currentDevice].systemVersion floatValue] >= 8.0) { if ([CLLocationManager authorizationStatus] == kCLAuthorizationStatusNotDetermined) { [self.manager requestAlwaysAuthorization]; } else if ([CLLocationManager authorizationStatus] != kCLAuthorizationStatusAuthorizedAlways) { [[[UIAlertView alloc] initWithTitle:@"title" message:@"message" delegate:self cancelButtonTitle:@"cancel" otherButtonTitles:@"Setting", nil] show]; } } else { if ([CLLocationManager authorizationStatus] == kCLAuthorizationStatusNotDetermined) { [self.manager startUpdatingLocation]; [self.manager stopUpdatingLocation]; } else if ([CLLocationManager authorizationStatus] != kCLAuthorizationStatusAuthorized) { [[[UIAlertView alloc] initWithTitle:@"title" message:@"message" delegate:self cancelButtonTitle:@"cancel" otherButtonTitles:@"Setting", nil] show]; } } } This is the codes I use it to require authorization.
