Question

我们有一个静态库（libAudioBulb.a），我在这里几乎用于所有项目。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，会出现构建时错误，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，但没有构建时错误。那么，我需要在这里配置任何构建设置吗？

Answer 1

我找到了两种方法来解决这个问题：

如果在其他链接器标志下设置-ObjC，则会导致重复。如果不需要，请删除它。
如果无法执行选项1，则删除包含这些类的项目之一中冲突类的.m文件。
