我也尝试在linkwith文件中添加AudioUnit，我得到一个框架未找到错误。我也尝试过添加CoreAudio来达到同样的效果。

对于代码转储感到抱歉。我希望有人可以帮助我，暂时陷入困境。

由于缺少对new（）的引用倾向于指示，您可能绑定了一个c ++库（或c ++ lib的包装器）。

你的库依赖于（c ++）其他的，也为那个添加[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)]
