我还尝试在 linkwith 文件中添加 AudioUnit，但出现未找到框架的错误。我也尝试将 CoreAudio 添加到相同的效果。

对不起代码转储。我希望有人可以帮助我，此刻陷入困境。

正如缺少对 new() 的引用所表明的那样，您可能正在绑定一个 c++ 库（或一个 c++ 库的包装器）。

如果您的库依赖于（c++）另一个，请为该库添加一个 [LinkWith] 属性

请记住，任何 c++ 库都应该在其 LinkWith 属性中设置属性 IsCxx=true

[assembly: LinkWith ("libMTSCRA.a", IsCxx=true, LinkTarget =  LinkTarget.ArmV7 | LinkTarget.ArmV6 | LinkTarget.Simulator, Frameworks = "AudioToolbox ExternalAccessory Foundation", ForceLoad = true)]
