ios - 在 UIPageViewController 中嵌入 UIScrollView 并禁用 pageView 滑动？

Question

我有一个UIView嵌入 UIScrollview 内部的子类(图形) UIViewController 里面这是 UIPageViewController 之一s 页面...我正在尝试禁用 UIPageViewController 的滚动以便用户扫描滚动条即可查看图表的最左侧，而无需向后翻页。我怎样才能做到这一点？ ScrollView 是完成这项工作的正确工具吗？

class HistoricalHealthDataViewController: UIViewController, UIScrollViewDelegate {


    @IBOutlet weak var graphScrollView: UIScrollView!

    @IBOutlet weak var hockeyTrackerGraphView: HockeyTrackerGraphView! {
        didSet {
            self.hockeyTrackerGraphView.graphableObjects = HFRGraphableObjects
        }
    }


    var HFRGraphableObjects: [HockeyTrackerGraphableObject] = [] 





    override func viewDidLoad() {
        super.viewDidLoad()

        graphScrollView.delegate = self


    }

    func scrollViewDidScroll(_ scrollView: UIScrollView) {

        if let parentPageViewController = parent as? HistoricalPageViewController {

            for gestureRecognizer in parentPageViewController.gestureRecognizers {
                print("gestureRecognizer")
                gestureRecognizer.isEnabled = false
            }
        }
    }
}

您没有显示它的代码，但我假设您实现了 UIPageViewControllerDataSource 协议(protocol)并且在某个地方您有方法:

func pageViewController(UIPageViewController, viewControllerBefore: UIViewController) -> UIViewController? {
}

func pageViewController(UIPageViewController, viewControllerAfter: UIViewController) -> UIViewController? {
}

如果您安排这些方法在禁用分页时返回 nil，则页面 View 将不会滚动到其他页面。
