问题是cocoapods还没有为arm64架构构建，因此当你构建它们时，它们不能链接。在更新并使用该体系结构之前，您可能无法使用这些包。您可以通过进入项目->目标(您的项目名称)->构建设置并将架构更改为标准架构(armv7, armv7s)，并将有效架构更改为armv7, armv7s来修复链接器错误。

Note though, this means you won't get the full power of the 64 bit processor. You said you are building for the 5s, so there may be some reason you need this. If you for some reason absolutely need that power (perhaps you are building a game), and desperately need those files, you could submit a pull request and then recompile the project to arm64 by setting those same fields to arm64 in the files you pulled from the open source projects. But, unless you really need these files to be 64 bit compatible, that seems like a bit of overkill for now.

编辑:有些人还报告说，将为活动架构构建设置为YES也是解决这个问题的必要条件。

截至2014-04-28，设置应该是这样的:

我也遇到过同样的问题，以上的方法都行不通。我不小心删除了下面目录下的文件。

文件夹位置:

~ /图书馆/开发/ Xcode / DerivedData /

如果你正在使用m1 (arm64)，你有问题，你可以在x86模式下运行:

右键点击xcode，点击获取信息按钮 勾选“使用罗塞塔”选项打开

这将是一个缓慢但有效的过程。

当morisunshine的回答指向正确的方向时，他的回答中的一个小调整解决了我的iOS8.2问题。

我通过设置来解决这个问题:

ARCHS = armv7

VALID_ARCHS = armv6 armv7 armv7s arm64

BUILD ACTIVE ARCHITECTURE ONLY= NO

这可能与libz有关。Dylib或libz。待定，只需将其添加到链接二进制文件的目标中，并尝试再次编译。
