我想调整我UIPageViewController在图像中的工作，目前1b可以转到2a等。我需要做什么来锁定图像中的方向？我是忘记了什么还是我使用了错误的逻辑。任何提示都会有很大帮助！

注意垂直UIPageViewController线在水平线内UIPageViewController

水平 UIPageViewController 代码

class MyPageViewController: UIPageViewController , UIPageViewControllerDataSource, UIPageViewControllerDelegate {

var pages = [UIViewController]()

override func viewDidLoad() {
    super.viewDidLoad()

    self.delegate = self
    self.dataSource = self

    let page1: UIViewController! = storyboard?.instantiateViewControllerWithIdentifier("page1")
    let page2: UIViewController! = storyboard?.instantiateViewControllerWithIdentifier("page2")
    let page3: UIViewController! = storyboard?.instantiateViewControllerWithIdentifier("page3")


    pages.append(page1)
    pages.append(page2)
    pages.append(page3)


    setViewControllers([page2], direction: UIPageViewControllerNavigationDirection.Forward, animated: false, completion: nil)
}

func pageViewController(pageViewController: UIPageViewController, viewControllerBeforeViewController viewController: UIViewController) -> UIViewController? {


    let currentIndex = pages.indexOf(viewController)!


    let previousIndex = abs((currentIndex …

我在网上找到了这个代码并进行了测试.它工作但它进入无限循环.我看到一些关于func为页面索引创建新内容的帖子.

链接到我发现代码的网站:http://samwize.com/2015/10/13/how-to-create-uipageviewcontroller-in-storyboard-in-container-view/

有人愿意编辑代码以便循环结束吗？

import UIKit

class MyPageViewController: UIPageViewController, UIPageViewControllerDataSource, UIPageViewControllerDelegate {

    var pages = [UIViewController]()

    override func viewDidLoad() {
        super.viewDidLoad()

        self.delegate = self
        self.dataSource = self

        let page1: UIViewController! = storyboard?.instantiateViewControllerWithIdentifier("page1")
        let page2: UIViewController! = storyboard?.instantiateViewControllerWithIdentifier("page2")
        let page3: UIViewController! = storyboard?.instantiateViewControllerWithIdentifier("page3")

        pages.append(page1)
        pages.append(page2)
        pages.append(page3)

        setViewControllers([page2], direction: UIPageViewControllerNavigationDirection.Forward, animated: false, 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] …
