我需要将我的音频文件转换为 PCM，为此我正在使用 iPhoneExtAudioFileConvertTest 示例项目。我已将该项目中的所有文件复制并粘贴到我需要的项目中。将 .cpp 的扩展名更改为 .mm。验证所有框架都在那里。但我仍然收到此错误。我搜索了很多，但除了我上面写的之外找不到任何东西。

这是错误。

Undefined symbols for architecture armv7s:
  "_DoConvertFile", referenced from:
      -[EditViewController convertAudio:DestPath:] in EditViewController.o
ld: symbol(s) not found for architecture armv7s
clang: error: linker command failed with exit code 1 (use -v to see invocation)

任何帮助将不胜感激。

谢谢
