Answer 1

CLLocationManager *lm = [[CLLocationManager alloc] init];
lm.delegate = self;
lm.desiredAccuracy = kCLLocationAccuracyBest;
lm.distanceFilter = kCLDistanceFilterNone; 
[lm startUpdatingLocation];

CLLocation *location = [lm location];

CLLocationCoordinate2D coord;
coord.longitude = location.coordinate.longitude;
coord.latitude = location.coordinate.latitude;
// or a one shot fill
coord = [location coordinate];

Answer 2

You will need to call CLLocationManager (See Apple Documentation). - startUpdatingLocation and - stopUpdatingLocation are one of the main methods you will be using.
