Question

I have an application that needs to detect the users location an drop some MKAnnotations around it on the MKMapView. How can I get notified about wether the user has selected YES on the Location Services prompt in order to then call my method to get the users location and add the annotations?

Answer 1

This will happen in the location manager delegate didUpdateToLocation;

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation {
    MyAnnotation * annotation = [[MyAnnotation alloc] initWithCoordinate:coordinate];
    [self.mapView addAnnotation:annotation];
}

You will need to create a MyAnnotation class. Take a look here: https://stackoverflow.com/a/2878806/1535038
