Question

只需将AFNetworking添加到我的项目中，在B＆amp; R之后我就会收到如下错误：

Undefined symbols for architecture i386:
"_SecCertificateCopyData", referenced from:
  -[AFURLConnectionOperation connection:willSendRequestForAuthenticationChallenge:] in       AFURLConnectionOperation.o

ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

已经检查过框架，libs和编译源代码，或者重新添加AFURLConnection.m，它也无法正常工作。

任何人都可以帮帮我吗？非常感谢...

Answer 1

您需要添加Security.framework才能构建它。

Answer 2

对我来说，我必须添加

Security.framework
SystemConfiguration.framework
MobileCoreServices.framework

Answer 3

我有一个非常类似的问题，并且看到大约15个mach -0链接器编译器错误消息。添加安全框架可将＃减少到7个错误。

进行了更多研究，发现您可能还需要通过xCode添加 SystemConfiguration.framework 。

这完全解决了我的问题。

作为一个FYI - 我使用的是xCode 5，目标是iOS 7并使用AFNetworking 2.0版。

添加作为答案，以防其他人发现简单地添加security.framework并不能为他们解决问题。

感谢Cody上面接受的答案。

Answer 4

OS X，我不得不补充：

Security.framework
SystemConfiguration.framework

APPLE MACH-O LINKED ERROR添加AFNetworking后
