Answer 3

Use this delegate method

-(void)locationManager:(CLLocationManager *)manager
        didUpdateToLocation:(CLLocation *)newLocation
               fromLocation:(CLLocation *)oldLocation {

        if (userLocation_) {
            [userLocation_ release];
        }
        userLocation_ = [newLocation retain];
    }
