You can use them to find out exactly where the current page is, and when it's moved, where it's headed. #### willScrollToPageAtIndex About to embark on a transition to a new page. ```swift func pageboyViewController(_ pageboyViewController: PageboyViewController, willScrollToPageAt index: Int, direction: PageboyViewController.NavigationDirection, animated: Bool) ``` #### didScrollToPosition Scrolled to a relative position along the way transitioning to a new page. ```swift func pageboyViewController(_ pageboyViewController: PageboyViewController, didScrollTo position: CGPoint, direction: PageboyViewController.NavigationDirection, animated: Bool) ``` #### didScrollToPage Successfully completed a scroll transition to a page. ```swift func pageboyViewController(_ pageboyViewController: PageboyViewController, didScrollToPageAt index: Int, direction: PageboyViewController.NavigationDirection, animated: Bool) ``` #### didReload Child view controllers have been reloaded. ```swift func pageboyViewController(_ pageboyViewController: PageboyViewController, didReloadWith currentViewController: UIViewController, currentPageIndex: PageIndex) ``` ### Navigation You can navigate programmatically through a `PageboyViewController` using `scrollToPage()`: ```swift pageViewController.scrollToPage(.next, animated: true) ``` - Infinite scrolling can be enabled with `.isInfiniteScrollEnabled`. - Interactive scrolling can also be controlled with `.isScrollEnabled`. ### Insertion & Deletion Pageboy provides the ability to insert and delete pages dynamically in the `PageboyViewController`. ```swift func insertPage(at index: PageIndex, then updateBehavior: PageUpdateBehavior) func deletePage(at index: PageIndex, then updateBehavior: PageUpdateBehavior) ``` *This behaves similarly to the insertion of rows in `UITableView`, in the fact that you have to update the data source prior to calling any of the update functions.* **Example:** ```swift let index = 2 viewControllers.insert(UIViewController(), at: index) pageViewController.insertPage(at: index) ``` *The default behavior after inserting or deleting a page is to scroll to the update location, this however can be configured by passing a `PageUpdateBehavior` value other than `.scrollToUpdate`.* ## ⚡️ Other Extras - `reloadData()` - Reload the view controllers in the page view controller. (Reloads the data source). - `.navigationOrientation` - Whether to orientate the pages horizontally or vertically. - `.currentViewController` - The currently visible view controller if it exists. - `.currentPosition` - The exact current relative position of the page view controller. - `.currentIndex` - The index of the currently visible page. - `.parentPageboy` - Access the immediate parent `PageboyViewController` from any child view controller. ### Animated Transitions Pageboy also provides custom transition support for **animated transitions**. This can be customized via the `.transition` property on `PageboyViewController`. ```swift pageboyViewController.transition = Transition(style: .push, duration: 1.0) ``` *Note: By default this is set to `nil`, which uses the standard animation provided by `UIPageViewController`.* ### Auto Scrolling `PageboyAutoScroller` is available to set up timer based automatic scrolling of the `PageboyViewController`: ```swift pageboyViewController.autoScroller.enable() ``` Support for custom intermission duration and other scroll behaviors is also available. ## 👨🏻‍💻 About - Created by [Merrick Sapsford](https://github.com/msaps) ([@MerrickSapsford](https://twitter.com/MerrickSapsford)) - Contributed to by a growing [list of others](https://github.com/uias/Pageboy/graphs/contributors). ## ❤️ Contributing Bug reports and pull requests are welcome on GitHub at [https://github.com/uias/Pageboy](https://github.com/uias/Pageboy). ## 👮🏻‍♂️ License The library is available as open source under the terms of the [MIT License](https://opensource.org/licenses/MIT).
