how to use Cell tower triangulation in iphone?

Question

In my app, I dont want to work off of location services. I want to get coordinates using Cell tower triangulation on the iphone.

Please tell me how to do this?

Answer 1

Use API called startMonitoringSignificantLocationChanges . From Apple docs -

startMonitoringSignificantLocationChanges service offers a significant power savings and provides accuracy that is good enough for most applications. It uses the device's cellular radio to determine the user's location and report changes in that location, allowing the system to manage power usage much more aggressively than it could otherwise.

So in code this is how it would look -

 self.locationManager     = [[[CLLocationManager alloc] init] autorelease];
 locationManager.delegate = self;
 [locationManager startMonitoringSignificantLocationChanges];
