Question

自从升级到OSX 10.9 Mavericks以来，我无法在安全框架中使用Keychain API，因为每次调用Keychain函数时，都会抛出一个未知异常。我尝试过许多不同的Keychain包装器实现，当它们调用任何Keychain函数时，它们都会抛出一个未知的异常。我甚至尝试过在他们的开发者网站上发布的示例代码apple并遇到了同样的问题。这是一个已知问题，如果是，那么修复的状态是什么？他们现在有没有办法使用Keychain？我已经在下面的苹果网站上提供了示例代码。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署？如果不是，许多电话会神秘地失败。我认为这开始发生在10.8左右。您得到了什么错误代码？

OSX 10.9 Mavericks Keychain API破了吗？
