swift：简单使用翻页控制器UIPageViewController

發布時間：2025/5/22 编程问答 18 豆豆

生活随笔收集整理的這篇文章主要介紹了 swift：简单使用翻页控制器UIPageViewController 小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

一、小敘

UIPageViewController是一個實現圖書閱讀的控制器，使用它可以設置書脊位置、單雙頁、過渡效果等，它是通過代理的方式來實現翻頁，也即上一頁、下一頁。最終這個UIPageViewController被包裝后添加到當前控制器即可。

二、直接上代碼

// // ViewController.swift // PageViewControllerDemo // // Created by 夏遠全 on 2017/1/19. // Copyright ? 2017年夏遠全.

ContentViewController)//如果是第0頁，返回nilif index == 0 || (index == NSNotFound) {return nil}index -= 1return self.viewControllerAtIndex(index: index)}//向后翻頁func pageViewController(_ pageViewController: UIPageViewController, viewControllerAfter viewController: UIViewController) -> UIViewController? {//獲取當前viewController的頁碼var index:Int = self.indexOfViewController(viewControler: viewController as! ContentViewController)if index == NSNotFound {return nil}index += 1//如果是最后一張，返回nilif index == self.pageContent.count {return nil}return self.viewControllerAtIndex(index: index)} }

三、效果（點擊屏幕實現翻頁）
