如何在UIView上显示滑动动作中的虚拟数据

import UIKit

class ViewController: UIViewController {
    var label: UILabel!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 创建一个UIView对象
        let view = UIView(frame: CGRect(x: 100, y: 100, width: 200, height: 200))
        view.backgroundColor = .lightGray
        self.view.addSubview(view)
        
        // 创建一个UILabel用于显示虚拟数据
        label = UILabel(frame: CGRect(x: 0, y: 0, width: 200, height: 50))
        label.textAlignment = .center
        label.textColor = .black
        view.addSubview(label)
        
        // 添加滑动手势识别
        let panGesture = UIPanGestureRecognizer(target: self, action: #selector(handlePanGesture(_:)))
        view.addGestureRecognizer(panGesture)
    }
    
    @objc func handlePanGesture(_ gesture: UIPanGestureRecognizer) {
        let translation = gesture.translation(in: gesture.view)
        
        // 根据滑动的偏移量计算虚拟数据的值
        let virtualData = calculateVirtualData(from: translation)
        
        // 更新UILabel的文本
        label.text = "Virtual Data: \(virtualData)"
        
        if gesture.state == .ended {
            // 滑动结束后的操作
        }
    }
    
    func calculateVirtualData(from translation: CGPoint) -> Int {
        // 根据滑动的偏移量计算虚拟数据的值
        let virtualData = Int(translation.x / 10) // 假设每移动10个点对应一个虚拟数据
        return virtualData
    }
}
