ios - 使滑动手势动画化

Question

当我在屏幕上向右或向左滑动时，我有滑动手势在标签栏之间切换，它改变了我在其中的标签栏 我该怎么做才能让它看起来像是在向右或向左滑动标签栏，而不是立即更改标签栏

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 实现此效果

如果你想从头开始构建它，你需要继承containerView。然后将 View Controller (childVC) 放入 scrollView(仅在水平方向滚动)。
