如何屏蔽UIPageViewController的滑动手势？

pageViewController.view.isUserInteractionEnabled = false

private func setupPageController() 
    pageViewController = UIPageViewController(transitionStyle:.pageCurl, navigationOrientation: .horizontal, options: nil)
    pageViewController.delegate = self
    pageViewController.dataSource = nil
    pageViewController.view.isUserInteractionEnabled = false



    viewControllers = [
        storyboard!.instantiateViewController(withIdentifier: "MyProfile"),
        storyboard!.instantiateViewController(withIdentifier: "Sync"),
        storyboard!.instantiateViewController(withIdentifier: "Assistance"),
        storyboard!.instantiateViewController(withIdentifier: "ChangePassword"),
        storyboard!.instantiateViewController(withIdentifier: "ContactUs"),
        storyboard!.instantiateViewController(withIdentifier: "SpeedTest"),
        storyboard!.instantiateViewController(withIdentifier: "Help")

    ]

    pageViewController.setViewControllers([viewControllerAtIndex(0)!], direction: .forward, animated: true, completion: nil)
    pageViewController.dataSource = self



    addChildViewController(pageViewController)
    view.addSubview(pageViewController.view)

    pageViewController!.view.frame = CGRect(x: 0, y:110, width: view.bounds.width, height: view.bounds.height - 70)//view.bounds
    pageViewController.didMove(toParentViewController: self)

    // Add the page view controller's gesture recognizers to the view controller's view so that the gestures are started more easily.

    // view.gestureRecognizers = pageViewController.gestureRecognizers

How do I Disable the swipe gesture of UIPageViewController?的可能重复

使用此解决方案但不起作用。

请分享您遇到的具体问题。根据您的问题，它似乎与另一个问题相似。

禁用数据源会导致问题我无法管理内容页面之间的导航，其中每个页面都由子视图控制器管理。

【参考方案1】：

您可以使用以下扩展启用或禁用SwipeGesture

extension UIPageViewController 

    func enableSwipeGesture() 
        for view in self.view.subviews 
            if let subView = view as? UIScrollView 
                subView.isScrollEnabled = true
            
        
    

    func disableSwipeGesture() 
        for view in self.view.subviews 
            if let subView = view as? UIScrollView 
                subView.isScrollEnabled = false
