    you should use method [locationManager startUpdateHeading] to enable get the angle relative to the geographic North Pole or magnetic North Pole. Then you can get the value in

     - (void)locationManager:(CLLocationManager *)manager didUpdateHeading:(CLHeading *)newHeading 
    {
       NSLog(@"%f",newHeading.trueHeading);
    }

    heading is a CLHeading object. As one look in the documentation would have told you, it also has properties for the true and magnetic headings in degrees.
