我一直在关注Seemu Apps的Youtube教程,但是我需要添加一个可选的ViewController来完成它

这个应用程序有2个tableViews显示车辆,如果我们点击第一个tableView的一行,然后第二个tableView将显示所选车辆的列表.

这是我们到现在为止所拥有的:(图片链接,因为我在stackOverFlow上没有得到十分的声誉)

一切都运行完美,但我希望能够在可选的detailViewController中显示信息(标签上有每个车辆的详细描述和更大的图像),具体取决于我们在secondTableViewControlle(或应用程序中的modelViewController)中单击的车辆究竟我是如何在tableViews之间的教程中关注的

我知道我们需要通过prepareForSegue方法传递数据,我已经理解了这在教程中的步骤,但是我们有2个tableviewControllers

例如：如果我们想要显示最后一个viewController,其中包含法拉利458的信息以及这款车的精彩图片

我们需要做些什么才能显示每辆车的信息？

PD：我是编程领域的初学者,也许我需要以非常简单的方式看待它

整个代码：
