I made scrollview page.
and swipe gesture
in scrollview. 1page->2page->3page->4page
but 4page->1page is not impossible.
I would like to make a rotation scrollview.
how I implement?
There are a few different ways to do this, and it really depends on what you're using the ScrollView for and how many pages you need to page through. Here they describe two such strategies with well-commented code so you can understand what each line of the code does.
