Method Detail

pageViewControllerDidFinishAnimatingPreviousViewControllersTransitionCompleted

default void pageViewControllerDidFinishAnimatingPreviousViewControllersTransitionCompleted(UIPageViewController pageViewController,
                                                                                            boolean finished,
                                                                                            NSArray<? extends UIViewController> previousViewControllers,
                                                                                            boolean completed)

Sent when a gesture-initiated transition ends. The 'finished' parameter indicates whether the animation finished, while the 'completed' parameter indicates whether the transition completed or bailed out (if the user let go early).

pageViewControllerSpineLocationForInterfaceOrientation
```
default long pageViewControllerSpineLocationForInterfaceOrientation(UIPageViewController pageViewController,
                                                                    long orientation)
```
Delegate may specify a different spine location for after the interface orientation change. Only sent for transition style 'UIPageViewControllerTransitionStylePageCurl'. Delegate may set new view controllers or update double-sided state within this method's implementation as well.

pageViewControllerWillTransitionToViewControllers

default void pageViewControllerWillTransitionToViewControllers(UIPageViewController pageViewController,
                                                               NSArray<? extends UIViewController> pendingViewControllers)

Sent when a gesture-initiated transition begins.

pageViewControllerPreferredInterfaceOrientationForPresentation

default long pageViewControllerPreferredInterfaceOrientationForPresentation(UIPageViewController pageViewController)

pageViewControllerSupportedInterfaceOrientations

default long pageViewControllerSupportedInterfaceOrientations(UIPageViewController pageViewController)
