// 导入UIKit框架
import UIKit

class ViewController: UIViewController {
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 创建UILabel对象
        let label = UILabel(frame: CGRect(x: 100, y: 100, width: 200, height: 50))
        label.text = "Hello World"
        label.isUserInteractionEnabled = true // 允许用户交互
        
        // 创建手势识别器对象
        let tapGesture = UITapGestureRecognizer(target: self, action: #selector(labelTapped(_:)))
        
        // 将手势识别器添加到UILabel上
        label.addGestureRecognizer(tapGesture)
        
        // 将UILabel添加到视图中
        view.addSubview(label)
    }
    
    // 手势识别器的触摸事件处理方法
    @objc func labelTapped(_ gesture: UITapGestureRecognizer) {
        if let label = gesture.view as? UILabel {
            let tappedText = label.text
            print("触摸的文本：\(tappedText ?? "")")
