没有找到I386符号

Question

我得到这个错误，当使用CFReadStreamRef

Undefined symbols for architecture i386:
  "_CFReadStreamCreateWithFTPURL", referenced from:
      -[FtpTestViewController clickMeToStart:] in FtpTestViewController.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我哪儿也找不到，有人能帮帮我吗?

谢谢!

在您的目标的"链接二进制与库"构建阶段是"CFNetwork.framework"包括吗?
