Question

我在屏幕右侧滑动或左侧更改标签栏即时切换标签栏之间的滑动手势如何制作它看起来像滑动到右侧或左侧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)
    }


}
