ios - 如何在 objective-c 中的谷歌地图上显示印度 map

Question

我是 iOS 新手，在 Google map 上显示印度 map 时遇到问题我的代码首先是这样的

 GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:18.516726
                                                            longitude:73.856255
                                                                 zoom:3];

    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
    {
        //Scrollview
         mapView = [GMSMapView mapWithFrame:CGRectMake(10, 140, 750, 350) camera:camera];
    }
    else
    {
        //Scrollview
         mapView = [GMSMapView mapWithFrame:CGRectMake(10, 140, 550, 350) camera:camera];

    }

但是当我使用 UIView 并像这样使用 IBOutlet 创建它时

IBOutlet GMSMapView *mapView;

比上面的代码不起作用。我怎样才能使用上面的坐标首先显示印度 map 。提前致谢!

Answer 1

获取当前位置坐标并传递这些相机位置

CLLocationCoordinate2D coordinate;
float latitude;
float longitude;

coordinate = [self getLocation];
latitude = coordinate.latitude;
longitude = coordinate.longitude;

//pragma mark ----: GET Coordinate2D :----

-(CLLocationCoordinate2D) getLocation
{
  CLLocation *location = [_locationManager location];
  coordinate = [location coordinate];
  return coordinate;
}

  CGRect frame = CGRectMake(0, 0, kSCREEN_WIDTH,kSCREEN_HEIGHT);
  GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:latitude longitude:longitude zoom:12];
  mapView_ = [GMSMapView mapWithFrame:frame camera:camera];
  mapView_.myLocationEnabled = YES;
  mapView_.delegate = self;

 [mapView_ setCamera:camera];
