I need to check that I'm not missing something about the details of CoreLocation. I am extending this code, and found this in the CLLocationManagerDelegate. It starts updating *location* and *heading*, then when it receives the *location* it stops updating the *heading* and vice-versa. This seems to be wrong to me, am I misunderstanding somethin…

gistfile1.m

- (void) locationManager:(CLLocationManager *)manager didUpdateHeading:(CLHeading *)newHeading {
    [manager stopUpdatingLocation];
    occurrence.heading = [NSNumber numberWithDouble:[newHeading trueHeading]];
    [occurrence didReceiveNewData];
}

- (void) locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation {
    [manager stopUpdatingHeading];
    occurrence.lat = [NSNumber numberWithDouble:newLocation.coordinate.latitude];
    occurrence.lon = [NSNumber numberWithDouble:newLocation.coordinate.longitude];
    occurrence.altitude = [NSNumber numberWithDouble:newLocation.altitude];
    occurrence.locationPrecision = [NSNumber numberWithDouble:newLocation.horizontalAccuracy];
    occurrence.speed = [NSNumber numberWithDouble:newLocation.speed];
    [occurrence didReceiveNewData];
}
