如何在我的班级中添加touchesBegan（）方法？

这是我的方法：

<!doctype html>
<html lang="<?php echo e(app()->getLocale()); ?>">
<head>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1">

    <title>Market</title>

</head>
<body>
    <ul>
        <?php 

            @foreach ($markets as $market) {
                echo market.name;
                <li>
                    <a href = {{ route('markets.show', $market) }}>
                        {{$market.name}}
                    </a>
                </li>
            }

         ?>
    </ul>
</body>

如果你的话，可以使用类扩展添加方法 class是UIView或UIWindow的子类：

extension YourClass {
    override open func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
        super.touchesBegan(touches, with: event)
        for touch in touches{
            let locationUser = touch.location(in: self)
        }
        print("touchesBegan")
    }
}

如何使用tochesBegan（）方法作为类的扩展？
