Question

I’m writing an iPhone application that uses GPS data. My problem is that the GPS never stops updating the locations (the arrow stays on the status bar) even if I kill the actual process. The only way to make it disappear is uninstalling the app, or disallowing it to use location in system settings.

This is how I create the location manager:

    // Create the location manager if this object does not
    // already have one.
    if (nil == locationManager)
        locationManager = [[CLLocationManager alloc] init];

    locationManager.delegate = regionTracker;

    locationManager.desiredAccuracy = kCLLocationAccuracyBest;

    // Set a movement threshold for new events.
    locationManager.distanceFilter = 1;

    [locationManager startUpdatingLocation];

In my app delegate, I run these two rows both in applicationWillTerminate: and applicationDidEnterBackground:

   [self.viewController.locationManager stopUpdatingLocation];
   [self.viewController.locationManager setDelegate:nil];

I nil the delegate because I saw some example where they did that, but should it really be needed?

Same as milonet mentioned, in my case I needed to call stopMonitoringSignificantLocationChanges in addition to the stopUpdatingLocation.
