如何在同一视图中收听不同控件上的点击手势？

import UIKit

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 创建第一个控件并添加点击手势
        let button1 = UIButton(frame: CGRect(x: 50, y: 100, width: 200, height: 50))
        button1.setTitle("Button 1", for: .normal)
        button1.addTarget(self, action: #selector(buttonTapped(_:)), for: .touchUpInside)
        self.view.addSubview(button1)
        
        // 创建第二个控件并添加点击手势
        let button2 = UIButton(frame: CGRect(x: 50, y: 200, width: 200, height: 50))
        button2.setTitle("Button 2", for: .normal)
        button2.addTarget(self, action: #selector(buttonTapped(_:)), for: .touchUpInside)
        self.view.addSubview(button2)
    }
    
    @objc func buttonTapped(_ sender: UIButton) {
        if sender.titleLabel?.text == "Button 1" {
            // 处理第一个按钮点击事件
            print("Button 1 tapped")
        } else if sender.titleLabel?.text == "Button 2" {
            // 处理第二个按钮点击事件
            print("Button 2 tapped")
        }
    }
}
