Projet SampleAppRef参考项目B.项目B的目标是libyodo1SDK_SNS-AD-ALS-GMG.a。
当我构建项目SampleAppRef时，它有这个错误，它告诉我重复的符号：
ld: duplicate symbol _OBJC_METACLASS_$_AdViewAdapterDomobImpl in /Users/dengjian/project/SDK_iOS/trunk/Yodo1SDK/Prj/yodo1SDK/build-yodo1SDK_SNS-AD-ALS-GMG/Release-iphonesimulator/libyodo1SDK_SNS-AD-ALS-GMG.a(AdViewAdapterDoMob.o) and /Users/dengjian/project/SDK_iOS/trunk/Yodo1SDK/Prj/yodo1SDK/build-yodo1SDK_SNS-AD-ALS-GMG/Release-iphonesimulator/libyodo1SDK_SNS-AD-ALS-GMG.a(AdViewAdapterDoMob.o) for architecture i386
和ld命令是：
Ld build-SampleAppRef/Release-iphonesimulator/SampleApp.app/SampleApp normal i386

当我删除参考项目B，并构建项目B单。然后将yodo1SDK_SNS-AD-ALS-GMG.a添加到项目SampleAppRef中，它运行良好！
当我从项目项目B中删除重复文件AdViewAdapterDoMob.h和AdViewAdapterDoMob.m时，它也运行良好！我可以运行并调用AdViewAdapterDoMob.m的代码。
项目SampleAppRef self没有任何“AdViewAdapterDomobImpl”代码。那为什么它有dumplcate符号？
有人可以给我一些提示吗？

尝试清除日志然后按停止。之后再次清除日志并退出xcode。重启mac并再试一次。看看是否有效。
