The view controllers passed to this method are those that will be visible after the animation has completed. Use a data source to provide additional view controllers to which users navigate.
If the transition style is UIPageViewController.TransitionStyle.pageCurl, the view controllers to pass in the viewControllers parameter depends on the spine location and the value of the isDoubleSided property:
Spine location | Double sided | What to pass |
|---|---|---|
Pass the page to be displayed on the left and the page to be displayed on the right. | ||
Pass the front of the page to be displayed and the back of the previously-displayed page. The back is used for the page turning animation. | ||
