APPLE MACH-O LINKED ERROR添加AFNetworking后
只需在我的项目中添加AFNetworking，在B＆R之后，我得到如下错误：
Undefined symbols for architecture i386: "_SecCertificateCopyData", referenced from: -[AFURLConnectionOperation connection:willSendRequestForAuthenticationChallenge:] in AFURLConnectionOperation.o "_SecCertificateCreateWithData", referenced from: ___44+[AFURLConnectionOperation pinnedPublicKeys]_block_invoke in AFURLConnectionOperation.o "_SecPolicyCreateBasicX509", referenced from: ___44+[AFURLConnectionOperation pinnedPublicKeys]_block_invoke in AFURLConnectionOperation.o -[AFURLConnectionOperation connection:willSendRequestForAuthenticationChallenge:] in AFURLConnectionOperation.o "_SecTrustCopyPublicKey", referenced from: ___44+[AFURLConnectionOperation pinnedPublicKeys]_block_invoke in AFURLConnectionOperation.o -[AFURLConnectionOperation connection:willSendRequestForAuthenticationChallenge:] in AFURLConnectionOperation.o "_SecTrustCreateWithCertificates", referenced from: ___44+[AFURLConnectionOperation pinnedPublicKeys]_block_invoke in AFURLConnectionOperation.o -[AFURLConnectionOperation connection:willSendRequestForAuthenticationChallenge:] in AFURLConnectionOperation.o "_SecTrustEvaluate", referenced from: ___44+[AFURLConnectionOperation pinnedPublicKeys]_block_invoke in AFURLConnectionOperation.o -[AFURLConnectionOperation connection:willSendRequestForAuthenticationChallenge:] in AFURLConnectionOperation.o "_SecTrustGetCertificateAtIndex", referenced from: -[AFURLConnectionOperation connection:willSendRequestForAuthenticationChallenge:] in AFURLConnectionOperation.o "_SecTrustGetCertificateCount", 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) 已经检查了框架，库和编译源，或者重新添加AFURLConnection.m，它也不起作用。
任何人都可以帮我吗？ 非常感谢…
您需要添加Security.framework才能生成。
对我来说，我必须补充
- Security.framework
- SystemConfiguration.framework
- MobileCoreServices.framework
我有一个非常类似的问题，并看到大约15马-0链接器编译器错误消息。 添加安全框架将＃减less到7个错误。
做了更多的研究，发现你可能还需要通过xCode添加SystemConfiguration.framework 。
这完全解决了我的问题。
作为一个参考 – 我使用xCode 5，目标iOS 7和使用AFNetworking版本2.0。
添加一个答案，以防其他人发现简单地添加security.framework并不能解决这些问题。
感谢上面的科迪接受的答案。
OS X，我不得不补充：
- Security.framework
- SystemConfiguration.framework
