以编程方式循环UIButton

import UIKit

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let buttonCount = 5
        
        for i in 0..<buttonCount {
            let button = UIButton(type: .system)
            button.frame = CGRect(x: 50, y: 100 + i * 50, width: 200, height: 40)
            button.setTitle("Button \(i+1)", for: .normal)
            button.addTarget(self, action: #selector(buttonTapped(_:)), for: .touchUpInside)
            
            view.addSubview(button)
        }
    }
    
    @objc func buttonTapped(_ sender: UIButton) {
        // 处理按钮点击事件
        if let title = sender.currentTitle {
            print("Button \(title) tapped")
        }
    }
}
