无法在真实设备上 运行 RealTimeRoom Google-Play-Games iOS ButtonClicker2000 示例

Question

我正尝试在 Real 设备上 运行 Google-Play-Games iOS 示例 ButtonClicker2000 项目。 （快速入门：https://developers.google.com/games/services/ios/quickstart
downloads: https://developers.google.com/games/services/downloads/）

1. 登录GooglePlayService的过程没有显示任何 错误。
   
2. 我确定我的 google 控制台项目设置正确。
   
3. 我在模拟器上启动时没有任何问题
   

BUT 在真实设备上（在 iphone 或 ipad 上无关紧要）当我点击快速匹配按钮时出现此错误（在底部）：

我该如何修复这个错误？非常感谢任何帮助

最终我找到了解决这个问题的方法。我不知道确切的时间，但是 google 的人为 C++ SDK 添加了 "objective c" headers。这些 headers 是 C++ 的一种绑定。于是C++ SDK变成了drag-and-dropable。
