将库添加到项目后，iOS _OBJC_CLASS错误

Question

我正在尝试将PayU money sdk添加到我的项目中。添加libiOSCustomBrowser.a文件后，它会出错：

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

  "_OBJC_CLASS_$_WKWebViewConfiguration", 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Link Binary with Libraries中，此引用存在。有什么问题？

Answer 1

也许该库不支持x86_64架构。 在

中删除x86_64架构

＆＃39;构建设置 - ＆gt;有效的架构＆＃39;

并重建。
