关于XCodeGLKit的警告弃用考虑迁移到Metal，而Apple电子邮件已弃用的API用法，请使用WKWebVie

我已经使用Buildbox 2.3.3完成了我的游戏，并在 Xcode 上清理了尽可能多的警告。但是，我已经从OpenGL迁移到Metal已经有好几个星期了，我认为这就是我在Xcode中出现错误的原因，说GLKit已被弃用，请考虑迁移到metal。

我试图将游戏上传到App Store connect，但没有解决此错误，但随后我立即收到一封电子邮件，说

ITMS-90809：已弃用的 API 用法，新应用不再使用 UIWebView，请改用 WKWebView。

我不知道如何转换我的代码以满足这一点，我将非常感谢一些指导，或者如果有人可以为我将OpenGL转换为金属重写我的代码。

我将在下面附上我正在使用的代码，如果有人可以帮助我，我将不胜感激。我已经在这个最后阶段停留了几个星期了，这非常令人沮丧。

正如你已经被告知的那样，你的问题有点不适合堆栈溢出。您可以开始将项目从OpenGL重写为Metal，并在出现任何问题时提出问题。

Apple 文档是一个很好的起点：

将 OpenGL 代码迁移到 Metal
在视图中混合金属和 OpenGL 渲染

您还可以观看WWDC 2019视频，并学习将基于OpenGL的应用程序过渡到Metal API的分步方法。

OpenGL 是可移植的并且得到广泛支持，所以不能使用它很遗憾。幸运的是，MetalANGLE框架几乎是GLKit的完美替代品。我已经开始在我的地图渲染库 CartoType 的开发分支中使用它，它工作正常：与 GLKit 相比，我看不到图形有任何不同，我只需要对我的代码进行一个小的更改即可使其工作 - 该更改可能是由于不正确使用 GLKit 引起的。

所以我的建议是：继续使用OpenGL并使用MetalANGLE。
