CLLocationManager's region monitoring vs significant location change

Question

In the documentation, it's not clear how region monitoring is implemented. Is it purely based on significant location change, or is it a mixture of significant location change and standard location service?

From experience, I'd say it uses significant location changes until it's close enough to have to use more specific location updates, but I have no data to prove it. Only thing I'm sure of is that it works too accurate to be just significant location changes, and doesn't appear to drain battery, so I don't think it constantly uses more precise location updates.

Thanks for the answer. So it seems to be some sort of smart combination of two locating modes. – lichen19853 Mar 05 '12 at 05:55
@lichen19853: I hope Filip is right (and therefore that I'm doing something wrong) but I'm only getting triggers every once in a while which leads me to believe that GPS is not taken into consideration. FYI, I live in Eugene OR, a town of about 150,000... – ari gold Sep 18 '12 at 18:53

Ya region monitoring started after IOS 4.0 and latter devices, its also working when app is terminated or ideal mode means its not app dependent service it is a ios dependent service like local notification you find your location or give a certain location coordinate to the regin and set region monitoring after specific given distance its enterin region and exitRegion methods called inside these function u do your wirk

Set a region

CLLocationDistance dist=200.0;
    CLRegion *region = [[CLRegion alloc]initCircularRegionWithCenter:coord radius:dist identifier:@"Test"];
    if([CLLocationManager regionMonitoringEnabled] && [CLLocationManager regionMonitoringAvailable])
        [locationManager startMonitoringForRegion:region desiredAccuracy:kCLLocationAccuracyBest];

-(void)locationManager:(CLLocationManager *)manager didExitRegion:(CLRegion *)region
{

}

-(void)locationManager:(CLLocationManager *)manager didEnterRegion:(CLRegion *)region
{

}
