Did you try CLLocationManager? – Celenacelene

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];

location will most likely be nil or out of date if you use this approach. The OP should be implementing locationManager:didUpdateToLocation:fromLocation: to receive updates as they come in. – Connive

That is true. If they want the best chance for accuracy, they should query the coordinates from inside that method. But this way should at least give them a good start. – Tellurate

Hi @BillBurgess this answer is worked for me in IOS 6 But IOS 5.1 Its not working... any alternates ... ! – Constrain

Probably changed in the last two years but now it should be: coord.longitude = location.coordinate.longitude; coord.latitude = location.coordinate.latitude; – Embrangle

This should be accepted as the correct answer, it is working for me (at least). – Nisen

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