- Method Detail
  - pageViewControllerViewControllerAfterViewController
```
UIViewController pageViewControllerViewControllerAfterViewController(UIPageViewController pageViewController,
                                                                     UIViewController viewController)
```
  - pageViewControllerViewControllerBeforeViewController
```
UIViewController pageViewControllerViewControllerBeforeViewController(UIPageViewController pageViewController,
                                                                      UIViewController viewController)
```
    In terms of navigation direction. For example, for 'UIPageViewControllerNavigationOrientationHorizontal', view controllers coming 'before' would be to the left of the argument view controller, those coming 'after' would be to the right. Return 'nil' to indicate that no more progress can be made in the given direction. For gesture-initiated transitions, the page view controller obtains view controllers via these methods, so use of setViewControllers:direction:animated:completion: is not required.
  - presentationCountForPageViewController
```
default long presentationCountForPageViewController(UIPageViewController pageViewController)
```
    The number of items reflected in the page indicator.
  - presentationIndexForPageViewController
```
default long presentationIndexForPageViewController(UIPageViewController pageViewController)
```
    The selected item reflected in the page indicator.
