Question

我得到了来自客户的IOS，Objective C项目，我想添加新功能和重构。 Project使用CocoaPods。在podfile中有一个来自bitbucket的私有库，需要登录。客户已向我发送了一封电子邮件，表示他没有登录，但他会向我发送源代码。这是我的问题。想象一下库A和库B（BlocksKit的自定义分支）。 A是依赖的，并且正在使用库B，而Main项目使用库A.所以我将库B构建为静态库，然后将其导入A.但是我得到了（null）：18个重复符号用于体系结构x86_64 这是日志：

ld: 18 duplicate symbols for architecture x86_64

我已经尝试过查看表单#import＆＃34; whatever.m＆＃34;，或者在没有任何运气的情况下查看编译源代码是否重复。所以我绝望了。任何帮助将不胜感激。

Answer 1

从项目中删除对.o库文件的引用并将其添加回项目..有时这可以解决您遇到的问题

将静态库导入其他库时，架构x86_64的重复符号
