如何使用相同的UIButton在不同的时间执行多个不同的动画？

import UIKit

class ViewController: UIViewController {
    var button: UIButton!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 创建UIButton对象
        button = UIButton(type: .system)
        button.frame = CGRect(x: 100, y: 100, width: 100, height: 50)
        button.setTitle("Button", for: .normal)
        button.addTarget(self, action: #selector(buttonTapped), for: .touchUpInside)
        view.addSubview(button)
    }
    
    @objc func buttonTapped() {
        // 执行缩放动画
        scaleAnimation()
        
        // 延迟1秒后执行旋转动画
        DispatchQueue.main.asyncAfter(deadline: .now() + 1) {
            self.rotateAnimation()
        }
    }
    
    func scaleAnimation() {
        UIView.animate(withDuration: 0.5, animations: {
            self.button.transform = CGAffineTransform(scaleX: 1.5, y: 1.5)
        }) { (_) in
            // 动画执行完毕后恢复初始状态
            self.button.transform = CGAffineTransform.identity
        }
    }
    
    func rotateAnimation() {
        UIView.animate(withDuration: 0.5, animations: {
            self.button.transform = CGAffineTransform(rotationAngle: CGFloat.pi)
        }) { (_) in
            // 动画执行完毕后恢复初始状态
            self.button.transform = CGAffineTransform.identity
        }
    }
}
