我当时正在将Kiip.me框架实现到我的iOS应用中。我已经添加了框架和所有内容并将其链接起来，但是当我运行它时，Apple Mach-O中出现了很多错误。对于我很久以前从Google Analytics(分析)中删除的文件，我也收到警告，即使我删除了所有引用，该文件仍在查找中。这是错误代码，我的主要问题是说的错误:
Undefined symbols for architecture x86_64:
"_OBJC_CLASS_$_Kiip", referenced from:
objc-class-ref in AppDelegate.o
objc-class-ref in CircleTableViewController.o
和
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
但是这里是完整的错误代码:

最佳答案
您的项目仍在引用GoogleAnalytics的库(最有可能在构建阶段->使用库链接二进制文件)。那是第一个错误(实际上只是警告)。
您要处理的第二个错误是包含的框架Kiip。它没有框架的64位版本，因此，如果您的项目构 build 置允许构建64位应用程序，则该框架将不会编译，因为您引用了Kiip并且无法使用它。
