自从升级到 OSX 10.9 Mavericks 后，我一直无法在 Security 框架中使用 Keychain API，因为每次调用 Keychain 函数时，它都会引发未知异常。我尝试了许多不同的 Keychain 包装器实现，它们在调用任何 Keychain 函数时都会抛出未知异常。我什至尝试过在他们的开发者网站上发布的示例代码苹果并遇到了同样的问题。这是一个已知问题吗？如果是，修复的状态如何？他们现在有任何使用钥匙串的方法吗？我在下面包含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
