IOS 5.0 ADDPlus实施问题-

当我试图通过AddPlus实现共享时，显示以下错误。我能做什么？有人知道吗

Undefined symbols for architecture armv7:
  "_OBJC_CLASS_$_Facebook", referenced from:
  objc-class-ref in libAddThis.a(ATFacebook.o)
  "_OBJC_CLASS_$_ATReachability", referenced from:
  objc-class-ref in libAddThis.a(ATGenericUtility.o)
  "_OBJC_CLASS_$_SBJSON", referenced from:
  objc-class-ref in libAddThis.a(ATTwitter.o)
  objc-class-ref in libAddThis.a(ATWebServiceAPI.o)
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

你检查过你所有的框架都被正确引用了吗？如果我没有弄错的话，这需要以下几点：

Security.framework,
CoreData.framework,
SystemConfiguration.framework,
MessageUI.framework,
Twitter.framework,

新的facebook SDK需要以下内容，并将其设置为ios6之前版本的可选内容

Social.framework,
AdSupport.framework,
Accounts.framework
