iOS 调用苹果自带地图导航不准确问题解决

// 苹果地图导航
+ (void)navAppleMap:(NSString *)lat lng:(NSString *)lng
{
    //坐标转换
    CLLocationCoordinate2D loc = CLLocationCoordinate2DMake(lat.doubleValue, lng.doubleValue);
    //将GPS转成高德坐标
    CLLocationCoordinate2D amapcoord = AMapCoordinateConvert(loc, AMapCoordinateTypeGPS);
    //用户位置
    MKMapItem *currentLoc = [MKMapItem mapItemForCurrentLocation];
    //终点位置
    MKMapItem *toLocation = [[MKMapItem alloc]initWithPlacemark:[[MKPlacemark alloc]initWithCoordinate:amapcoord addressDictionary:nil] ];
    
    NSArray *items = @[currentLoc,toLocation];
    
    NSDictionary *dic = @{
                          MKLaunchOptionsDirectionsModeKey : MKLaunchOptionsDirectionsModeDriving,
                          MKLaunchOptionsMapTypeKey : @(MKMapTypeStandard),
                          MKLaunchOptionsShowsTrafficKey : @(YES)
                          };
    
    [MKMapItem openMapsWithItems:items launchOptions:dic];
}

//将GPS转成高德坐标
CLLocationCoordinate2D amapcoord = AMapCoordinateConvert(loc, AMapCoordinateTypeBaidu);
