Xcode

Question

我们有一个静态库 (libAudioBulb.a)，我将其用于这里几乎所有的项目。静态库包含 AFNetworking 的源文件。在我的一个项目中，我也需要使用 AFNetworking，但是，当我包含 AFNetworking 的源文件时，出现构建时错误，显示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却没有构建时错误。那么，我需要在此处配置任何构建设置吗？

Answer 1

我找到了两种解决方法：

如果在其他链接器标志下设置 -ObjC，则会导致重复。因此，如果不需要，请将其删除。
如果无法完成选项 1，则在包含这些类的项目之一中删除冲突类的 .m 文件即可。
