【问题描述】：

我将 AFNetworking 2.0 添加到我的项目中。 我没有使用 CocoaPods 就做到了——我只是将文件添加到项目中，确保将文件复制到目标。

当我尝试编译项目时，出现以下错误：

Undefined symbols for architecture i386:
  "_SecCertificateCopyData", referenced from:
      _AFCertificateTrustChainForServerTrust in AFSecurityPolicy.o
  "_SecCertificateCreateWithData", referenced from:

我的项目有什么问题？

【参考方案1】：

您在项目中缺少的 ios 框架。 我敢打赌，从我看到的名字来看，安全框架就是其中之一。

【参考方案2】：

#import <Security/Security.h> 在您的 PCH 文件中 + 确保该库位于“Link Binary With Libraries”中。

【参考方案3】：

只需在您的项目中添加 security.framework。
