Swift:如何根据按钮点击将结果显示到标签

import UIKit

class ViewController: UIViewController {
    var resultLabel: UILabel!
    var button: UIButton!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 创建标签
        resultLabel = UILabel(frame: CGRect(x: 50, y: 100, width: 200, height: 30))
        resultLabel.text = "结果将显示在这里"
        view.addSubview(resultLabel)
        
        // 创建按钮
        button = UIButton(frame: CGRect(x: 50, y: 150, width: 100, height: 30))
        button.setTitle("点击按钮", for: .normal)
        button.setTitleColor(.blue, for: .normal)
        button.addTarget(self, action: #selector(buttonClicked), for: .touchUpInside)
        view.addSubview(button)
    }
    
    @objc func buttonClicked() {
        // 在按钮点击事件中更新标签的文本
        resultLabel.text = "按钮被点击了"
    }
}
