first of all you need a class implementing the protocol CLLocationManagerDelegate. So at least you need to implement the method:

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

After that create an instance of CLLocationManager, set the delegate and start updating the location:

CLLocationManager *locationManager = [[CLLocationManager alloc] init];
locationManager.delegate        = self;  //SET YOUR DELEGATE HERE
locationManager.desiredAccuracy = kCLLocationAccuracyBest; //SET THIS TO SPECIFY THE ACCURACY
[locationManager startUpdatingLocation];

After calling startUpdatingLocation, your implementation of locationManager: didUpdateToLocation: fromLocation gets called as soon as a location fix occurs. The parameter newLocation contains your actual location. BUT the location manager will fix a location as soon as possible, even if your specifed accuracy is not given. For this case you have to check the accuracy of the new location by your own.
