“无法取消存档名为UITableViewController的元素”
我一直在按照“构build你的第二个iOS应用程序”的教程步骤一步，我已经遇到了这个错误后教程承诺，所有的错误将消失，但错误没有显示，直到其他错误之后所有纠正，我试图编译它。
错误：
The document "MainStoryboard_iPhone.storyboard" could not be opened. Failed to unarchive element named "UITableViewController". 这里是教程的链接。
这是我的故事板以XML格式

我是完全陌生的客观的C和Xcode，所以我不知道我在做什么错，甚至真正从哪里开始的错误。 如果有人知道如何解决这个错误，或者同时学习Objective C和iOS开发的更好的（在线）资源，我会非常感激。
这是我的项目，如果有人想看看我的。
我能够发现我在教程上做了什么错误。 不是拖动TableViewController并删除DetailViewController，而是将一张表拖放到详细视图顶部的控制器上。 我不知道我是怎么错过的，昨天我一定很累。
另外，任何人在苹果iPhone开发教程上都卡住了，我强烈推荐iTunes上的“斯坦福iPhone开发”系列。 我正在经历它，这是惊人的。 它解释了苹果教程从未做过的事情（比如在属性中使用strong vs weak，在属性中使用atomic vs nonatomic）。 我知道我已经开始理解客观的C语言了，因为当我陷入困境时，我真的知道该怎么去Google。
