使用多个框架会产生clang：错误：链接器命令失败，退出代码为1

Question

就像我说的..我正在使用两个框架，FlashIz和MWPhotoBrowser。 （实际上，我使用的更多，但它们不会出错。）

在构建项目时，出现如下错误：

    /Users/Korneel/Documents/stage-genius/trunk/IOS/gTicket/FlashizEmbeddedLibrary.embeddedframwork/FlashizEmbeddedLibrary.framework/FlashizEmbeddedLibrary(MBProgressHUD.o)



ld: 29 duplicate symbols for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

因此，我从这个错误中得出了那两个框架正在使用相同的“框架”（例如MBProgressHUD）的信息。 所以我想删除其中之一？ 但是我不知道怎么办。有人吗？ 问题是，我似乎找不到此文件？

Answer 1

这里的问题是重复 。 MBProgressHUD已添加两次（来自libMWPhotoBrowser.a和FlashizEmbeddedLibrary ）

因此，从任何一个库中删除。

Answer 2

它表明这是由于重复的符号。 在您的项目中，有MBProgressHUD多个类。 请仅使用一个类，并删除其他类。 这样可以解决您的问题，
