In iOS, the navigation controller has its own slide-by default, and when the user slides to the left (left edge) of the interface, the slide-through function is available. However, we often need to slide around the screen at any point in the development process and need to go back to the previous interface.More to say unintentionally, directly read the code:Part:Part of the Code (second interface):#import "
