使用多个框架会产生clang:error:linker命令失败，退出代码为1

Using multiple frameworks gives clang: error: linker command failed with exit code 1

本文关键字：失败 命令 linker 退出 代码 error 框架 clang      更新时间：2023-10-16

就像我说的。。我使用两个框架，FlashIz和MWPhotoBrowser。（事实上，我使用了更多，但他们不会给出错误。）

在构建项目时，我遇到了这样的错误：

ld: 29 duplicate symbols for architecture armv7

因此，我从这个错误中推断出，这两个框架使用的是相同的"框架"，如MBProgressHUD。所以我想去掉其中的一个？但我不知道怎么。。有没有人遇到过类似的问题？问题是，我似乎找不到这些文件？

这里的问题是重复。MBProgressHUD添加了两次（来自libMWPhotoBrowser.a和FlashizEmbeddedLibrary）

因此，从任何一个libs中删除。

这表明它是由于重复的符号造成的。在您的项目中有多个类别的MBProgressHUD。请只使用一个类并删除另一个类。这将解决您的问题，
