Question

我在Xcode中创建了一个Tabbed Bar应用程序，第一个选项卡是Decors。我问了一个关于将XIB项目集成到StoryBoard选项卡项目的上一个问题。

我已经成功地整合了它，并且它可以工作但是当我按下其中一个Deocrs或表格单元格时，我得到以下错误：

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[UIViewController _loadViewFromNibNamed:bundle:] loaded the "SelectedCellViewController" nib but the view outlet was not set.

如果我将原始警报放入我的项目中，单元格链接将再次开始工作。

以下是我的项目的图片，链接和代码，所以你可以看到它是如何工作的

检查身份检查器中“要点击的控制器”.XIB继承的类。看来你没有为“要显示”的XIB和同一个XIB的视图出口设置类。
