Question

我正在尝试使用scifihifi-iphone (from Github)来存储和检索用户名和密码。但是，当我添加类SFHFKeychainUtils时，我收到以下错误：

  "_kSecAttrAccount", referenced from:
      _kSecAttrAccount$non_lazy_ptr in SFHFKeychainUtils.o

我要离开的是什么？当我点击错误时，它不会将我带到代码中的任何位置。

添加Security.framework，然后重建。有时我发现我必须建立干净然后重建。

要添加此功能，请右键单击Xcode中的目标，然后单击添加 - >现有框架，然后选择（或导航）到Security.framework。
