推荐答案

这当然是可能的，这是使它工作的线：

It is certainly possible, here is the very line that makes it work:

[self.map setTransform：CGAffineTransformMakeRotation（-1 * newHeading .magneticHeading * M_PI / 180）];

为了接收标题事件，你需要创建一个 CLLocationManager 并执行 [locationManager startUpdatingHeading];

In order to receive the heading events, you need to create a CLLocationManager and do [locationManager startUpdatingHeading];
