@interface PSPDFSpreadView : UIView

The spread view is responsible for laying out one or multiple page views.

It ensures the best display for the pages it is responsible for and makes sure pages are shown in the correct order (e.g. respecting the page binding).

A spread describes a collection of continuous pages that are grouped in a logical container from the layout. E.g. if you have a book, when the book is open you will always see two pages next to each other. These two pages build one spread. If you have a stack of loose paper on the other hand, you always only see one page, so a spread only consists of one page in that example.
