C++ 新手错误苹果Mach-O连接器错误

我是新来的，但我有一个苹果Mach-O链接器错误：

这是我的应用程序代理！ // //AppDelegate.m //vcContainentTut // //由汗于2013年5月1日创建。 //版权所有（c）2013 AK。版权所有。 //

---

您的错误是由于您试图使用尚未告知项目（因此链接器）存在的代码造成的。您需要将依赖项添加到项目中。在本例中，框架定义了您试图使用的功能。

您是否将Framework MediaPlayer.Framework添加到项目中？啊，添加之后，删除了3个错误。然而，还有一些其他问题。例如：“_SecCertificateCopyData”，引用自：-[AFURLConnectionOperation connection:willSendRequestForAuthenticationChallenge:]，在AFURLConnectionOperation.oah中，我需要添加security.framework！
