使滑动手势动画

Question

当我在屏幕右侧滑动或左侧更改标签栏时，我有滑动手势在标签栏之间切换我是如何制作它所以看起来它滑动到右侧或左侧标签栏而不是立即改变标签栏

class SwipeGesture: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        let left = UISwipeGestureRecognizer(target: self, action: #selector(swipeLeft))
        left.direction = .left
        self.view.addGestureRecognizer(left)

        let right = UISwipeGestureRecognizer(target: self, action: #selector(swipeRight))
        right.direction = .right
        self.view.addGestureRecognizer(right)

    }

    @objc func swipeLeft() {
        let total = self.tabBarController!.viewControllers!.count - 1
        tabBarController!.selectedIndex = min(total, tabBarController!.selectedIndex + 1)

    }

    @objc func swipeRight() {
        tabBarController!.selectedIndex = max(0, tabBarController!.selectedIndex - 1)
    }


}

您可以使用此pod来实现此效果

如果要从头开始构建它，则需要子类化containerView 。 然后将视图控制器（childVCs）放在scrollView （仅在水平方向上滚动）。
