如何快速制作UIButton的右侧先出现，然后出现左侧

let button = UIButton(frame: CGRect(x: 0, y: 0, width: 100, height: 50))
button.setTitle("Button", for: .normal)
button.backgroundColor = UIColor.blue

// 设置初始状态
button.transform = CGAffineTransform(translationX: 100, y: 0)

// 设置动画效果
UIView.animate(withDuration: 0.5, delay: 0, options: .curveEaseInOut, animations: {
    // 平移或缩放到右侧位置
    button.transform = CGAffineTransform.identity
}, completion: { _ in
    // 设置第二个动画效果
    UIView.animate(withDuration: 0.5, delay: 0, options: .curveEaseInOut, animations: {
        // 平移或缩放到左侧位置
        button.transform = CGAffineTransform(translationX: -100, y: 0)
    }, completion: nil)
})

// 将UIButton添加到视图中显示
view.addSubview(button)
