-ObjC链接器标志-当尝试将其添加到“其他链接器标志”时，我得到一个错误

Question

我正在尝试将facebook SDK3.2添加到我的应用程序中，但是在我添加了-ObjC链接器标志(如他们的视频中所述)之后，我收到了许多重复的警告，并且我无法运行该应用程序并显示以下错误：

duplicate symbol _OBJC_IVAR_$_GAI.defaultTracker_ in:
    /Users/gool/proj/Frameworks/GANT/libGoogleAnalytics.a(GAI.o)
    /Users/gool/proj/Frameworks/GANT/libGoogleAnalytics_debug.a(GAI.o)

    ld: 172 duplicate symbols for architecture i386
    clang: error: linker command failed with exit code 1 (use -v to see invocation)
