如何使用苹果钥匙串？

我正试图使用scifihifi-iphone（来自Github）来存储和检索用户名和密码，但是当我添加SFHFKeychainUtils类时，出现了以下错误：

  "_kSecAttrAccount", referenced from:

我漏掉了什么？当我点击错误时，它没有带我到代码的任何位置。

看起来像是链接器错误。这是你的代码第一次与钥匙串有关吗？ - Matt Ball

你也添加了Keychain框架吗？ - jantimon

添加Security.framework，然后重新构建。有时我发现我必须进行清理并重新构建。

要添加此内容，请在Xcode中右键单击您的目标，然后选择“添加”-> “现有框架”，并选择（或导航到）Security.framework。
