iOS架构x86_64 Xcode的未定义符号 [英] iOS Undefined symbols for architecture x86_64 Xcode

问题描述

我已经在我的应用程序中安装了一些第三方框架.一切正常，突然有一天我开始出现以下错误.请注意，只有当我尝试在iOS Simulator上运行我的应用程序时，才会出现这些链接器错误.

I have installed some third party frameworks in my app. Every thing was working fine and suddenly one day i started to get the following errors. Please note that these linker errors appear only when i try to run my app on iOS Simulator.

任何帮助将不胜感激.如果我在实际设备上而不是在模拟器上进行调试，则可以调试，构建和存档我的项目.我已经通过cocapods添加了所有这些框架，并且我正在使用Xcode 7.3.

Any help will be highly appreciated. I can debug, build and archive my project, if i do it on actual device but not on simulator. I have added all these frameworks via cocapods and i am using Xcode 7.3.

推荐答案

我遇到了同样的错误.像下面一样

I had faced the same error. Like below

Undefined symbols for architecture x86_64:
  "_OBJC_CLASS_$_AFJSONRequestSerializer", referenced from:
      objc-class-ref in CuebiqSDK(BADispatcherHelper.o)
  "_OBJC_CLASS_$_AFURLSessionManager", referenced from:
      objc-class-ref in CuebiqSDK(BADispatcherHelper.o)
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我没有在项目中添加 AFURLSessionManager 相关的类，如错误所述.因此，我添加了所有AFNetworking类来解决该问题.确保将它们添加到项目目标中并显示在构建阶段"->编译源代码"

I haven't added the AFURLSessionManager related classes in my project as mentioned in error. So, I added all the AFNetworking classes solved the problem. Make sure they are added to project target and shown under Build phases->Compile Sources
