试图在Unity中使用Xamarin.iOS制作的库

问题描述 投票：1回答：1

我使用Xamarin.iOS和Visual Studio创建了库。 Foundation和JavaScriptCore名称空间都在库中使用。

我想在Unity中使用这个库。当我将这个库放在Unity的Assets> Plugins / iOS文件夹中并编写代码来调用我创建的库时，会发生错误。它说没有Xamarin.iOS.dll，所以我添加了它，最后我可以编译它们。

但是当我尝试构建它时，还有另一个错误。错误信息如下;

IL2CPP error for method 'Foundation.NSObject ARKit.ARAnchor::Copy(Foundation.NSZone)' in assembly '/Users/MyName/Documents/JavaScriptRuntimeTest/Temp/StagingArea/Data/Managed/Xamarin.iOS.dll'
Additional information: Stack empty.

是否有可能在Unity中使用Xamarin.iOS制作的库？谢谢，

据我所知，目前还没有关于如何在Unity中使用Xamarin或在Xamarin中使用Unity的文档。两个运行时不一样。

Xamarin有自己的引擎：urhosharp
