    ld: framework not found AudioUnit
    clang: error: linker command failed with exit code 1 (use -v to see invocation)

有人已经解决了这个问题吗？

Answer 1

您可能会不小心#import 一个 .m 文件而不是一个 .h。使用 Cmd+Shift+F 并搜索“.m”（不带引号）。它很可能属于警告中提到的类别之一。如果没有，请清理并再次运行。

或

此错误可能是由于您的项目中缺少某些库。

检查您的构建阶段 -> 将二进制文件与库链接。您的任何框架都可能已从那里删除。

添加它并清理并构建您的项目。它应该可以正常工作。

希望对你有帮助。
