ios - sharekit 会给出关于遵从的警告。我应该忽略它吗？

Question

我在以下位置获得了 sharekit 库：

https://github.com/ShareKit/ShareKit/wiki/Installing-sharekit

我按照所有说明操作，现在当我运行我的应用程序时，我收到以下警告：

GTMMethodCheckMethodChecker: Class UIKeyboardCandidateUtilities does not conform to @protocol(NSObject), so won't be checked
2013-03-25 23:57:42.971 Daily Tamatar[25762:c07] GTMMethodCheckMethodChecker: Class WebMIMETypeRegistry does not conform to @protocol(NSObject), so won't be checked

我应该担心吗？我对协议和一致性相当陌生？

谢谢
