Update SCViewController.m

The delegate protocol method
- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation 
	fromLocation:(CLLocation *)oldLocation
    is deprecated in iOS 6. I propose replacing it with  - (void)locationManager:(CLLocationManager *)manager 
didUpdateLocations:(NSArray *)locations
