如何防止iphone在Objective C中出现校准指南针？

Question

当我将MKMapView的userTrackingMode设置为MKUserTrackingModeFollowWithHeading时，我的应用程序一次又一次地向我显示指南针校准。如何防止这种情况？ 这是我的locationManager的初始化。

self.locationManager = [[CLLocationManager alloc] init];
self.locationManager.desiredAccuracy = kCLLocationAccuracyBest;
self.locationManager.distanceFilter = 5;
self.locationManager.delegate = self;
self.locationType = LocationManagerTypeNone;

Answer 1

CLLocationManagerDelegate有一种禁用校准显示的方法，

但我不确定MKMapView是否有一个你无法改变的...
