ios - why self.locationManager stopUpdatingLocation doesn't stop location update

Problem: It seems I can't stop Core Location from sending updates to my app / tracking.

What am I doing: In my viewWillAppear I call self.locationManager and pass it to a method to show user's location on the map (an instance of MKMapView). The getter is overridden to check for availability of the serive, to see whether its authorized. If so, it allocs/inits and startMonitoringSignificantLocationChanges and returns.

In viewDidDisappear, I call [self.locationManager stopUpdatingLocation]. But still I can see the location icon in the status bar. Even when I terminate the app by double tapping the home button and closing it, the icon is still there... even after extended amount of time (10+ minutes). When I go to the Settings App, it tells me that my app is still using location services (purple icon).

Question: What am I missing here? Why location update doesn't stop?

Thanks in advance.

The opposite of startMonitoringSignificantLocationChanges is not stopUpdatingLocation, it is stopMonitoringSignificantLocationChanges.

You probably want to replace startMonitoringSignificantLocationChanges with startUpdatingLocation for the sake of more regular updates, unless you have a specific reason for monitoring only for significant location changes.

Check out the CLLocation documentation for further detail.
