我可以为.a库创建一个合适的dll
我的LinkWith文件
[assembly: LinkWith ("libSwiperAPI.a", IsCxx = true,
LinkTarget = LinkTarget.Simulator | LinkTarget.ArmV7 | LinkTarget.ArmV7s,
ForceLoad = true, Frameworks = "CoreAudio AudioToolbox AVFoundation MediaPlayer",
LinkerFlags = "-ObjC -lc++" )]
在此尝试使用链接标志-lstdc ++ -lz但也没有用。
我甚至尝试在Addition mtouch Argjuments和-gcc_flags中添加-cxx。
当我尝试在我的演示项目中使用dll文件时。我收到错误

有人可以帮我解决这个问题。
答案 0 :(得分：1)
终于找到了错误!!
[assembly: LinkWith (..., LinkerFlags = "-lstdc++ -lz" )]
在iOS Binding Projet中
选项＆gt;构建＆gt;编译器＆gt;加法参数
-cxx -gcc_flags "-stdlib=libstdc++ -L${ProjectDir} -lMylibrary -force_load ${ProjectDir}/libMylibrary.a”
在我的演示应用程序中
选项＆gt; iOS Buidl＆gt; Addtional mtouch Arguments
--gcc_flags="-stdlib=libstdc++"
通过在所有地方提供适当的标志，它解决了我的问题。
