objective c - Example for startMonitoringSignificantLocationChanges

Question

I am new to iPhone programming. I am looking for an example or a demo on how to use startMonitoringSignificantLocationChanges method with the CoreLocation Manager.

I am confused by the documentation because, I am not sure if the same delegate method is called as in the case of invoking startUpdatingLocation. (i.e. the delegate locationManager: (CLLocationManager *)manager didUpdateToLocation: (CLLocation *)newLocation fromLocation: (CLLocation *)oldLocation is called)

Any help on this would be appreciated. Also, I am testing it on the simulator by subclassing of CLLocationManager. This subclass provides a simulation of location services when running on the iPhone Simulator. Is there a better way to test this.

Answer 1

I have done a bit of testing with the significant change API. I posted a sample project on GitHub that lets you play with regular and significant location updates.

This question might also shed some light on what happens when you get woken up for a significant change event.

Update

Another thing you should be aware of, there is a bug in CoreLocation in 4.1. Basically if your app is in the background, then it will crash when core location tries to wake you up. It is fixed in 4.2.
