OSX 10.9 Mavericks 钥匙串 API 已损坏

Question

自从升级到OSX 10.9 Mavericks以来，我一直无法在安全框架中使用钥匙串API，因为每次调用钥匙串函数时，它都会抛出一个未知的异常。我尝试了许多不同的钥匙串包装器实现，当它们调用任何钥匙串函数时，它们都会抛出未知的异常。我什至尝试了苹果在其开发人员网站上发布的示例代码，并遇到了同样的问题。这是一个已知问题吗，如果是，修复的状态是什么？他们现在有什么办法使用钥匙串吗？我已经包含了苹果网站下面的示例代码。这是链接： https://developer.apple.com/library/mac/documentation/Security/Conceptual/keychainServConcepts/03tasks/tasks.html#//apple_ref/doc/uid/TP30000897-CH205-TP9

您的应用程序是否已正确签名？ 如果不是，许多调用将神秘地失败。 我认为这在 10.8 左右开始发生。 您得到什么错误代码？
