將庫添加到項目後出現iOS _OBJC_CLASS錯誤

Question

我正在嘗試將PayU錢sdk添加到我的項目中。並加入libiOSCustomBrowser.a文件後，它給人的錯誤：

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)

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

在構建階段，在鏈接二進制與圖書館，這個參考存在。哪裏不對？

Answer 1

也許該庫不支持x86_64體系結構。在

刪除x86_64體系 '構建設置 - >有效架構'

和重建。
