UIPageViewControllerとは

横スワイプによるページ送り

サンプル

1. 初期のViewControllerとは別に２つUIViewControllerをstoryboardに追加する
2. それぞれクラス名をViewControllerとSecondViewControllerとThirdControllerとする
3. それぞれのStroyboardIdをFirstViewControllerとSecondViewControllerIdとThirdViewControllerIdとする
4. UIPageViewControllerをstoryboardに追加する
5. 追加したUIPageViewControllerのクラス名をPageViewControllerとする
6. PageViewControllerを初期起動するように"Is InItial View Controller"をonにする

import UIKit
class PageViewController: UIPageViewController, UIPageViewControllerDataSource {
   override func viewDidLoad() {
       super.viewDidLoad()
       self.setViewControllers([getFirstViewController()], direction: .Forward, animated: true, completion: nil)
       self.dataSource = self
   }
   override func didReceiveMemoryWarning() {
       super.didReceiveMemoryWarning()
   }
   private func getSecondViewController() -> UIViewController {
       return storyboard!.instantiateViewControllerWithIdentifier("SecondViewControllerId")
   }
   private func getFirstViewController() -> UIViewController {
       return storyboard!.instantiateViewControllerWithIdentifier("FirstViewControllerId")
   }
   private func getThirdViewController() -> UIViewController {
       return storyboard!.instantiateViewControllerWithIdentifier("ThirdViewControllerId")
   }
   // 次へ
   func pageViewController(pageViewController: UIPageViewController, viewControllerBeforeViewController viewController: UIViewController) -> UIViewController? {
       if viewController.isKindOfClass(ThirdViewController) {
           return getSecondViewController()
       } else if viewController.isKindOfClass(SecondViewController) {
           return getFirstViewController()
       } else {
           return nil
       }
   }
   // 前へ
   func pageViewController(pageViewController: UIPageViewController, viewControllerAfterViewController viewController: UIViewController) -> UIViewController? {
       if viewController.isKindOfClass(ViewController) {
           return getSecondViewController()
       } else if viewController.isKindOfClass(SecondViewController) {
           return getThirdViewController()
       } else {
           return nil
       }
   }
}
