尝试编译AFNetworking 2.0时，架构i386的未定义符号

Question

我在项目中添加了AFNetworking 2.0。 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，我收到以下错误：

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

      _AFPublicKeyTrustChainForServerTrust in AFSecurityPolicy.o
ld: symbol(s) not found for architecture i386

我的项目出了什么问题？

Answer 1

项目中缺少的iOS框架。 我打赌安全框架就是我看到的名字之一。

Answer 2

PCH文件中的

#import <Security/Security.h> +确保库位于“Link Binary With Libraries”中。

Answer 3

只需在项目中添加security.framework即可。
