多个标记Google Map iOS SDK

Question

我正在努力在iOS 8.0的Google地图中获取多个标记。我当前的代码是：

ResourceGroep *rsg = [ResourceGroep alloc]init;
GMSCameraPosition *camera = nil;

for (int i = 0; i < [rsg.chosenResourceArray count]; i++)
{
    camera = [GMSCameraPosition cameraWithLatitude:[loc.Latitude doubleValue]
                               longitude:[loc.Long doubleValue]
                               zoom:15];

    mapView_ = [GMSMapView mapWithFrame:self.view.bounds camera:camera];
    mapView_.myLocationEnabled = NO;

    CLLocationCoordinate2D position = { [rsg.Latitude doubleValue], [rsg.Long    doubleValue] };
    GMSMarker *marker = [GMSMarker markerWithPosition:position];
      marker.title = [NSString stringWithFormat:@"Marker %i", i];
      marker.appearAnimation = YES;
      marker.flat = YES;
      marker.snippet = @"";
      marker.map = mapView_;
}

[self.view addSubview:mapView_];

我已经遍历了数组，但是我只能看到1个标记，而数组计数大约是2还是3取决于用户选择的对象。我想念什么？

检查一下：

   ResourceGroep *rsg = [ResourceGroep alloc]init;
   GMSCameraPosition *camera = nil;

   camera = [GMSCameraPosition cameraWithLatitude:[loc.Latitude doubleValue]
                            longitude:[loc.Long doubleValue]
                                 zoom:15];

   mapView_ = [GMSMapView mapWithFrame:self.view.bounds camera:camera];
   mapView_.myLocationEnabled = NO;

   for(int i = 0; i < [rsg.chosenResourceArray count]; i++)
   {




      CLLocationCoordinate2D position = { [rsg.Latitude doubleValue], [rsg.Long    doubleValue] };
      GMSMarker *marker = [GMSMarker markerWithPosition:position];
      marker.title = [NSString stringWithFormat:@"Marker %i", i];
      marker.appearAnimation = YES;
      marker.flat = YES;
      marker.snippet = @"";
      marker.map = mapView_;
  }

 [self.view addSubview:mapView_];

我刚刚更改了一些代码的位置。
