滑动单元格获得更多按钮时的UIPanGestureRecognizer如何在用户滑动不足一半时使视图反弹

let panGesture = UIPanGestureRecognizer(target: self, action: #selector(handlePanGesture(_:)))
cell.addGestureRecognizer(panGesture)

@objc func handlePanGesture(_ gesture: UIPanGestureRecognizer) {
    let translation = gesture.translation(in: self.view)
    let velocity = gesture.velocity(in: self.view)
    
    // 根据位移和速度信息进行相应的处理
    // ...
}

@objc func handlePanGesture(_ gesture: UIPanGestureRecognizer) {
    let translation = gesture.translation(in: self.view)
    let velocity = gesture.velocity(in: self.view)
    
    if translation.x < 0 && abs(translation.x) < cell.frame.width / 2 {
        // 触发反弹效果
        UIView.animate(withDuration: 0.3) {
            // 更新单元格的位置
            cell.frame.origin.x = 0
        }
    }
}
