没有为架构armv7找到的符号

Question

我将LinkedInIOS登录演示与我当前的应用程序集成在一起： https://github.com/jeyben/IOSLinkedInAPI

还添加支持类＆＃34; AFNetworking＆＃34;。

如下所述，它给了我一个错误：

Undefined symbols for architecture armv7:
  "_kUTTagClassMIMEType", referenced from:
      _AFContentTypeForPathExtension in AFURLRequestSerialization.o
  "_kUTTagClassFilenameExtension", referenced from:
      _AFContentTypeForPathExtension in AFURLRequestSerialization.o
  "_UTTypeCreatePreferredIdentifierForTag", referenced from:
      _AFContentTypeForPathExtension in AFURLRequestSerialization.o
  "_UTTypeCopyPreferredTagWithClass", referenced from:
      _AFContentTypeForPathExtension in AFURLRequestSerialization.o
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

请建议我解决它。我的部署目标是5.0。
