XIB加载 ---- [UIViewController _loadViewFromNibNamed:bundle:] loaded the "QuestionAndAnswerController" nib but the view outlet was not set

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

   新创建一个ViewController文件，去加载一个xib文件，结果提示这个问题，思来想去，感觉没有什么错啊，于是就重新创建了一边，设置如下：

如图所示，我勾选了 【Also create XIB file】，结果发现，并没有报错，介个就好玩了。 后来一想，肯定是连线有问题。结果打开文件一看，果然是 view属性对应的连线没有设置。

设置之后，程序正常运行，我又可以得瑟了。

   切记：自定义XIB文件是，一定要设置好属性关联
