Question

My Storyboard 您好我是编程的新手，但我正在尝试创建一个IOS应用程序，我在其中显示事实并教授一个主题，然后在最后做一个测验。我认为几个多视图控制器最适合这个，每个主题都有一个视图控制器，然后是每个测验的视图控制器。（这是正确的做法吗？）

我还没有开始讨论事实部分，因为我不知道如何在点击按钮时从swift中的数据文件（只有随机数据）按顺序运行一系列事实，（任何想法最好的是什么）解决方案是为了这个？）。在第三个视图控制器，它是我的测验后的教学部分，我试图实现它并通过第二个视图控制器的按钮访问它，它进入第二视图控制器罚款，然后从导航栏返回，但它赢了让我访问第三个视图控制器（我的测验打开），当它尝试加载它崩溃并进入调试屏幕。任何帮助将不胜感激。因为一旦我有一个排序应该更容易做其他人。
