question about the Core Location service

I am working on the Core Location and getting the pop-up message from CCLocation Manager like a below

Code:

Iphone would like to use your current location-----> DONT ALLOW OR YES

Processing ( this is what I thought) : after entering either "OK" or "Don't allow",I have just notified the CLLocationManagerDelegate about my current location and this process will trigger one of methods called

Code:

(void)locationManager:(CLLocationManager *)managerdidUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation

My question is that : is above processing correct Please correct me if I have just made a mistake some where. All comments are welcomed. Thanks
