检查这个：我知道，这确实是我使用问题中提到的常规xib文件所要做的。但主要的问题是，如果我已经从故事板加载了一个视图，并且我发现好像nibBundle和nibName被填充了，为什么我不能使用我以前在XIB中使用的方法呢？另外，为什么尽管子类在情节提要中有其控制器，却调用super的loadView？另外，视图控制器已经被应用程序本身实例化了。是的，我知道，我不知道为什么你不能，我猜苹果希望我们的故事板只实例化控制器，如果你想处理视图，那么你没有其他选择来创建xib。我在控制器和Storybard中创建视图。但是，当一个视图被使用两次时，我将其放在xib中，重复的视图（甚至在故事板中）会在维护代码时导致问题。嗯
