Detailed explanation of the principle:
The above method uses UIScrollView and UIPageControl to implement the screen flip and slide function. UIScrollView is a scrollable view container that can display content beyond the screen size and scroll through swipe gestures. UIPageControl is a page indicator that displays the current page and the total number of pages, and allows the user to switch pages.

Flowchart:
The following is the basic flowchart for using UIScrollView and UIPageControl to implement the scrolling and sliding function:
