我按照https://developers.google.com/cast/docs/ios_sender中描述的说明操作，但是当我尝试构建项目时，我得到了36个链接器错误，如下所示：

我从github下载了示例Hello，Text应用程序并且它没有错误地构建。我在这里做错了什么？

更新：根据@Rhythmic Fistman的建议，我链接了安全框架，并消除了23个链接器错误。但是，仍有13个链接器错误如下：

有什么想法吗？

您需要关联Security.framework和CFNetwork.framework。

Xcode＆gt;您的项目＆gt;构建阶段＆gt; Link Binary with Libraries＆gt; +＆gt; Security.framework

转到链接器标志并添加＆＃34; -ObjC＆＃34;标志
