我们有一个静态库（libAudioBulb.a），我在这里几乎所有的项目都使用它。静态库包含 AFNetworking 的源文件。在我的一个项目中，我还需要使用 AFNetworking，但是，当我包含 AFNetworking 的源文件时，出现构建时错误，表明我在项目和静态库中有重复的符号。但是，奇怪的是，在另一个项目中，我只是做了同样的事情，但没有构建时间错误。那么，我需要在这里配置任何构建设置吗？

我找到了两种方法来解决这个问题：

  1. 如果 -ObjC 在其他链接器标志下设置，那么这将导致重复。因此，如果不需要，请删除它。

  2. 如果选项 1 无法完成，则可以在包含这些类的项目之一中删除冲突类的 .m 文件。
