Question

我有一个UIPageViewController，它显示五个ViewControllers（包含在ViewControllers的数组中）。我正在使用手势识别器来向后/向前移动页面，而不是viewControllerBefore / viewControllerAfter方法。它工作正常，但是页面突然改变。我想要的动画类似于我以前应用.scroll时获得的动画。我希望能够显示两个ViewControllers，类似于我们在.scroll动画中缓慢滑动时所遇到的情况。你能建议怎么做吗？谢谢。

正如我在此问题中提到的，我遇到了滚动问题-> [{Disable swiping in horizontal UICollectionView inside my PageViewController to swipe in UIPageViewController 因此，我决定对此行发表评论-> self.dataSource = self 我决定明确提供与手势相关的功能。

@objc func handleSwipe(gesture: UISwipeGestureRecognizer) {
    print(gesture.direction)
    switch gesture.direction {
    case UISwipeGestureRecognizer.Direction.down:
        print("down swipe")
    case UISwipeGestureRecognizer.Direction.up:
        print("up swipe")
    case UISwipeGestureRecognizer.Direction.left:

        self.setViewControllers([ViewControllerArray[1]], direction: .forward, animated: false, completion: nil)

    case UISwipeGestureRecognizer.Direction.right:

        self.setViewControllers([ViewControllerArray[2]], direction: .forward, animated: false, completion: nil)

    default:
        print("other swipe")
    }
}

将animated参数更改为true

@objc func handleSwipe(gesture: UISwipeGestureRecognizer) {
    print(gesture.direction)
    switch gesture.direction {
    case UISwipeGestureRecognizer.Direction.down:
        print("down swipe")
    case UISwipeGestureRecognizer.Direction.up:
        print("up swipe")
    case UISwipeGestureRecognizer.Direction.left:

        self.setViewControllers([ViewControllerArray[1]], direction: .forward, animated: true, completion: nil)

    case UISwipeGestureRecognizer.Direction.right:

        self.setViewControllers([ViewControllerArray[2]], direction: .forward, animated: true, completion: nil)

    default:
        print("other swipe")
    }
}

即使没有在UIPageViewController中设置数据源，也希望具有.scroll动画
