【问题描述】：

是否可以增加 UINavigationController 的边缘大小interactivePopGestureRecognizer 以响应用户触摸？

即是否可以从屏幕中间向右滑动以移动和弹出当前顶部 Viewcontroller 与从左屏幕边缘相同的方式？

你可以试试 PAN 手势识别器

【参考方案1】：

    override func viewDidLoad() 
        super.viewDidLoad()
        let swipeRight = UISwipeGestureRecognizer(target: self, action: #selector(respondToSwipeGesture))
        swipeRight.direction = .right
        self.view.addGestureRecognizer(swipeRight)

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

    

    // you can track all direction swipe like below, and to do that first you have to add gesture in the view you want to track.
    @objc func respondToSwipeGesture(gesture: UIGestureRecognizer) 
        if let swipeGesture = gesture as? UISwipeGestureRecognizer 
            switch swipeGesture.direction 
            case .right:
                // push pop here
                print("Swiped right")
            case .down:
                print("Swiped down")
            case .left:
                // push pop here
                print("Swiped left")
            case .up:
                print("Swiped up")
            default:
                break

感谢您的回答，但主要问题是如何使用与默认滑动关闭相同的动画来处理这种从左到右的手势。将视图边缘移动到触摸位置并根据触摸位置和速度关闭或移回视图。
