在UIView (不是UITableViewCell)上滑动以显示操作

import UIKit

class CustomView: UIView {
    override init(frame: CGRect) {
        super.init(frame: frame)
        
        let panGesture = UIPanGestureRecognizer(target: self, action: #selector(handlePan(_:)))
        self.addGestureRecognizer(panGesture)
    }
    
    required init?(coder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
    
    @objc func handlePan(_ gesture: UIPanGestureRecognizer) {
        let translation = gesture.translation(in: self)
        
        switch gesture.state {
        case .changed:
            // 根据滑动偏移量更新视图位置或显示额外功能
            self.frame.origin.x += translation.x
        case .ended:
            // 根据滑动的最终位置执行相应操作
            if self.frame.origin.x > self.bounds.width / 2 {
                // 执行操作A
            } else {
                // 执行操作B
            }
            // 恢复视图原始位置
            UIView.animate(withDuration: 0.3) {
                self.frame.origin.x = 0
            }
        default:
            break
        }
        
        gesture.setTranslation(.zero, in: self)
    }
}
