自升级到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。我已经尝试了许多不同的Keychain包装器实现，当他们调用任何Keychain函数时，它们都会抛出未知的异常。我甚至尝试过在他们的开发人员网站上公布的示例代码，并遇到同样的问题。这是一个已知的问题，如果是这样，修复的状态是什么？他们现在是否有任何方式使用钥匙串？我已经包含了苹果网站下面的示例代码。这里是链接：https://developer.apple.com/library/mac/documentation/Security/Conceptual/keychainServConcepts/03tasks/tasks.html#//apple_ref/doc/uid/TP30000897-CH205-TP9OSX 10.9小牛钥匙串API破碎？
