cocoa - OSX 10.9 Mavericks 钥匙串(keychain) API 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 Keychain API，因为每次调用 Keychain 函数时，都会抛出未知异常。我尝试了钥匙串(keychain)包装器的许多不同实现，当它们调用任何钥匙串(keychain)函数时，它们都会抛出未知的异常。我什至尝试过苹果在其开发人员网站上发布的示例代码，但遇到了同样的问题。这是一个已知问题吗？如果是，修复的状态如何？现在有什么方法可以使用Keychain吗？我在下面提供了来自苹果网站的示例代码。这是链接:https://developer.apple.com/library/mac/documentation/Security/Conceptual/keychainServConcepts/03tasks/tasks.html#//apple_ref/doc/uid/TP30000897-CH205-TP9

您的申请是否已正确签名？如果不是这样，许多调用将会神秘地失败。我认为这开始发生在 10.8 左右。您收到什么错误代码？
