架构i386 armv7的未定义符号，armv7s MedioEvent k-invite sdk

Question

我尝试通过此处和其他论坛上的许多解决方案来删除以下错误。

    Undefined symbols for architecture armv7:
      "_kABPersonPhoneProperty", referenced from:
          +[InviteHelpers findPhoneNumbersForContact:] in libMedioEvent.a(InviteHelpers.o)
      "_ABPersonCopyArrayOfAllLinkedPeople", referenced from:
          _CopyValuesFromLinkedContact in libMedioEvent.a(InviteHelpers.o)
      "_ABMultiValueCopyLabelAtIndex", referenced from:
          _CopyValuesFromLinkedContact in libMedioEvent.a(InviteHelpers.o)
      "_ABMultiValueAddValueAndLabel", referenced from:
          _CopyValuesFromLinkedContact in libMedioEvent.a(InviteHelpers.o)
      "_ABMultiValueCopyValueAtIndex", referenced from:
          +[InviteHelpers findEmailsForContact:] in libMedioEvent.a(InviteHelpers.o)
          +[InviteHelpers findPhoneNumbersForContact:] in libMedioEvent.a(InviteHelpers.o)
          _CopyValuesFromLinkedContact in libMedioEvent.a(InviteHelpers.o)
          +[InviteHelpers findContactTwitter:] in libMedioEvent.a(InviteHelpers.o)

我已经在项目中包含了MedioEvent SDK及其预编译的源代码，并且还将其包含在Framework和Library搜索路径中。困扰我的是它来自libMedioEvent.o。

我是否必须包含＆＃34; InviteHelpers＆＃34; sdk也是？
