“An error has occurred” message when Location Services is turned off

Question

In the iOS simulator, I am prompted to turn on my location when the app attempts to pinpoint my location. However, on an iphone running 4.1, I get a generic "An error has occurred" without any type of prompt. I checked my project's NSLogs/Alerts and none of them have a generic "An error has occurred." Is anyone aware of why this happens?

UPDATE:

This happens when a user has their location turned off. I have yet to figure out why the user is not prompted to turn it on and why - (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error is not working.

Answer 1

The answer below solved the bug for me. This handled the error and prevents the prompt from appearing.
