You don't get a direct callback from this alert. However, if the user does not allow Core Location usage, you'll receive a -locationManager:didFailWithError: with a kCLErrorDenied error to your CLLocationManagerDelegate.

Since iOS 4.2, you can also listen to -locationManager:didChangeAuthorizationStatus: or check the authorizationStatus of CLLocationManager. This gives you a detailed status.
