獲取磁頭值

Question

我可以在下面的代表上得到磁航向值嗎？如果是這樣，我怎麼能把它變成UILabel？

- (void)locationManager:(CLLocationManager *)manager didUpdateHeading:(CLHeading *)newHeading { 

}

- (void)locationManager:(CLLocationManager *)manager didUpdateHeading:(CLHeading *)newHeading { 
    myLabel.text = [NSString stringWithFormat:@"%f", [newHeading magneticHeading]]; 
}
