Create a navigation controller

So I wonder if you all know that before you want to create a navigation control, you need to create at least one view controller? The pointer to the top-level view (the official root view of the application) is passed to the navigation controller for initialization. The navigation controller calls it the root view controller. It represents the view controller at the bottom of the navigation path: this main view of the application does not provide a back button, but it is also a base for generating other views.

To create a navigation controller, first create a view class that will be used as the root view controller. Post-use navigation controller

InitWithRootViewController method implementation, such as:

When using a navigation controller, you need to attach its view to the window. When created, the view controller is bound to it, so when the navigation controller is added to the window, you can see the view controller.

The navigation controller automatically draws itself and the currently active view controller, and the default is the root view controller. When a new view is pushed into the stack of the navigation controller, the new view is displayed until the user presses the back button or navigates somewhere else. To push a view into the navigation controller, you can use the pushViewController method to do this:

Finally, when the view is pushed onto the stack, the Select back button is automatically added to the navigation. The name of the back button will also be the same as the name of the previous view controller in the stack. When the user chooses the back button, the view controller is kicked off the stack, and the previous view at the lower level is transferred back to the screen.
