警告XCODELGKIT不考虑迁移到金属，而苹果电子邮件不推荐API使用，使用WKWebVIEW代替UIWebVIEW

我已经使用Buildbox2.3.3完成了我的游戏，并在Xcode上清除了尽可能多的警告。然而，我已经在这个星期，我从OpenGL迁移到金属，我认为这是我在XCODE中有错误的原因，表示GLITK被弃用，考虑迁移到金属。 我试图在未解决此错误的情况下将游戏上载到App store connect，但随后我立即收到一封电子邮件，其中说

ITMS-90809:不推荐使用API，新应用不再使用UIWebView， 改用WKWebView

我不知道如何去转换我的代码，以满足这一点，我真的很感激一些指导，或者如果有人可以重写我的代码为我转换OpenGL到金属

我将在下面附上我正在使用的代码，如果有人能帮助我，我将不胜感激。我已经被困在这个最后阶段好几个星期了，这非常令人沮丧

正如已经告诉您的，您的问题有点不适合堆栈溢出。您可以开始将您的项目从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：

---

您还可以观看并学习一种逐步将基于OpenGL的应用程序转换为Metal API的方法。

OpenGL是可移植的，并且受到广泛支持，因此不能使用它很遗憾。幸运的是，该框架几乎是GLKit的完美替代品。我已经开始在地图渲染库的开发分支中使用它，它工作正常：与GLKit相比，我看不出图形有什么不同，我只需对代码进行一个小的更改就可以使其正常工作，而这个更改可能是由于GLKit的使用不正确造成的

---

因此，我的建议是：继续使用OpenGL并使用MetalANGLE。

很抱歉，这超出了StackOverflow的范围。通过更改几行代码，将游戏从OpenGL移植到Metal是不可能的。然而，OpenGL只是被弃用了——您仍然可以使用它。您得到的错误与此无关。它似乎在代码库中的某个地方，甚至在使用UIWebView的依赖项中。这需要用WKWebView替换，然后你应该能够提交应用程序。好的，我很感谢你的回复，我认为我必须完全转换为金属才能提交给苹果，这是我的第一款游戏，所以我还是新手。所以我只需要找到UIWebView并替换它，谢谢。我上下搜索了我的代码库，但我没有UIWebView。我仍然收到苹果的电子邮件，我正在尝试从我的故事板中的GLKView迁移到WKWebView。你认为这能解决问题吗？我已经尝试过了，但是当我将视图更改为WKWebviewNo时，我的游戏似乎正在加载超过主页。不，你不能将用于将OpenGL内容呈现到WKWebview Safari的GLKView替换为GLKView。您是否检查了您的依赖项（包括cocos2d）是否包含UIWebView？是的，我检查了依赖项中没有UIWebView
