地圖定位的座標和mapview中顯示的當前位置信息不一致

// 準確打開方式

- (void)mapView:(MKMapView *)mapView didUpdateUserLocation:(MKUserLocation *)userLocation {

    CLLocationCoordinate2D coordinate=userLocation.coordinate;//位置座標

    MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(coordinate, 500, 500);//定位放大

 

      [self.mapView setRegion:region animated:YES];

}

 

//有偏差的打開方式

-(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations{

    CLLocation *location=[locations firstObject];//取出第一個位置

    CLLocationCoordinate2D coordinate=location.coordinate;//位置座標

    NSLog(@"經度：%f,緯度：%f,海拔：%f,航向：%f,行走速度：%f",coordinate.longitude,coordinate.latitude,location.altitude,location.course,location.speed);

    

    //若是不須要實時定位，使用完即便關閉定位服務

    [_locationManager stopUpdatingLocation];

    MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(coordinate, 500, 500);//定位放大

    [self.mapView setCenterCoordinate:coordinate animated:YES];

    [self.mapView setRegion:region animated:YES];

 }
