次のコードを使用してPageViewControllerを構築しています。 私の質問は、私の "Front"と "Back" viewControllerでページのスクロールを無効にしたり有効にしたりする方法です。Page Scrolling（Swift）の無効化と有効化
class PageController: UIPageViewController, UIPageViewControllerDataSource, UIPageViewControllerDelegate {
var pages = [UIViewController]()
override func viewDidLoad() {
super.viewDidLoad()
self.delegate = self
self.dataSource = self
let page1: UIViewController! = storyboard?.instantiateViewControllerWithIdentifier("Front")
let page2: UIViewController! = storyboard?.instantiateViewControllerWithIdentifier("Back")
pages.append(page1)
pages.append(page2)
setViewControllers([page1], direction: UIPageViewControllerNavigationDirection.Forward, animated: true, completion: nil)
}
func pageViewController(pageViewController: UIPageViewController, viewControllerBeforeViewController viewController: UIViewController) -> UIViewController? {
let currentIndex = pages.indexOf(viewController)!
let previousIndex = abs((currentIndex - 1) % pages.count)
return pages[previousIndex]
}
func pageViewController(pageViewController: UIPageViewController, viewControllerAfterViewController viewController: UIViewController) -> UIViewController? {
let currentIndex = pages.indexOf(viewController)!
let nextIndex = abs((currentIndex + 1) % pages.count)
return pages[nextIndex]
}
func presentationCountForPageViewController(pageViewController: UIPageViewController) -> Int {
return pages.count
}
func presentationIndexForPageViewController(pageViewController: UIPageViewController) -> Int {
return 0
}
}
