iOS高德地图 指南针(罗盘)不转的解决方法

self.mapView = [[MAMapView alloc] initWithFrame:CGRectMake(0, 0, CGRectGetWidth(self.view.bounds), CGRectGetHeight(self.view.frame))];
self.mapView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
self.mapView.delegate = self;

[self.view addSubview:self.mapView];

self.mapView.userTrackingMode = MAUserTrackingModeFollowWithHeading;(核心)

[self.mapView setCompassImage:[UIImage imageNamed:@"[email protected]"]];
           

或者

//地图懒加载
- (MAMapView *)mapView{
       if (!_mapView) {
        _mapView =  [[MAMapView alloc] initWithFrame:CGRectMake(0, kH_SegmentOfCustomeHeight, CGRectGetWidth(self.view.bounds), CGRectGetHeight(self.view.frame) - kH_SegmentOfCustomeHeight)];

    _mapView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
    _mapView.delegate = self;
    _mapView.showsUserLocation = YES;    //YES 为打开定位，NO为关闭定位
//    _mapView.desiredAccuracy = kCLLocationAccuracyKilometer;
//    _mapView.distanceFilter = kCLLocationAccuracyKilometer;
//    _mapView.headingFilter  = 90;

    _mapView.zoomLevel = 14;
    //自定义定位经度圈样式
    _mapView.customizeUserLocationAccuracyCircleRepresentation = YES;

          //地图跟踪模式
 //    _mapView.userTrackingMode = MAUserTrackingModeFollow;
     _mapView.userTrackingMode = MAUserTrackingModeFollowWithHeading;
     _mapView.showsCompass = YES;
     [_mapView setCompassImage:[UIImage imageNamed:@"[email protected]"]];

    //后台定位
    _mapView.pausesLocationUpdatesAutomatically = NO;
    _mapView.allowsBackgroundLocationUpdates = NO;//iOS9以上系统必须配置
    }
    return _mapView;
}
