将库添加到项目后出现iOS _OBJC_CLASS错误

Question

我正在尝试将PayU钱sdk添加到我的项目中。并加入libiOSCustomBrowser.a文件后，它给人的错误：

ld: warning: directory not found for option '-L/Users/Jenaveve/myApp/Utilities/PayUSdk' 
Undefined symbols for architecture x86_64: 
    "_OBJC_CLASS_$_WKUserContentController", referenced from: 
     objc-class-ref in libiOSCustomBrowser.a(PUCBWebVC.o)

ld: symbol(s) not found for architecture x86_64 
clang: error: linker command failed with exit code 1 (use -v to see invocation) 

在构建阶段，在链接二进制与图书馆，这个参考存在。哪里不对？

Answer 1

也许该库不支持x86_64体系结构。在

删除x86_64体系 '构建设置 - >有效架构'

和重建。
