ios - 统一 5 和 IL2CPP : cannot build

Question

过去几天我一直在绞尽脑汁试图将我的机器人应用程序移植到 iOS。

大部分代码是内部代码，仅使用 UnityAds、SIS(简单 IAP 系统)和 GooglePlayGames 插件。

启用 IL2CCP 后，它甚至不会在 Unity 5(最新版本)上构建。我收到以下错误:

IL2CPP error for type 'GooglePlayGames.Native.PInvoke.PInvokeUtilities/OutStringMethod' in assembly '/Temp/StagingArea/Data/Managed/Assembly-CSharp.dll'
Additional information: Build a development build for more information. Exception has been thrown by the target of an invocation.

Failed running /Applications/Unity/Unity.app/Contents/Frameworks/il2cpp/il2cpp.exe --copy-level=None --enable-generic-sharing --enable-unity-event-support --emit-null-checks --enable-array-bounds-check --enable-symbol-loading

其他人也遇到了问题，特别是 Google 游戏服务插件。我还没有看到解决方案，但是 Unity 链接上的一位 Unity 员工说他会调查一下。

更新:最新的 Unity 补丁 5.0.0p2 为我修复了这个错误: http://unity3d.com/unity/qa/patch-releases
