Swift 4-按下按钮时的动作-循环？

import UIKit

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let button = UIButton(type: .system)
        button.setTitle("按下按钮", for: .normal)
        button.addTarget(self, action: #selector(buttonPressed), for: .touchUpInside)
        button.frame = CGRect(x: 100, y: 100, width: 200, height: 50)
        view.addSubview(button)
    }
    
    @objc func buttonPressed() {
        // 在这里执行按下按钮时的动作
        print("按钮被按下了")
    }
}

for i in 1...5 {
    print(i)
}
