UITouchGestureRecognizer的简单子类，设置minimumPressDuration

Question

我只是想做这样的事情：

class UITouchyGestureRecognizer: UILongPressGestureRecognizer {

    required init? .. something .. {
        super.init .. who knows .. 
        print("wth?")
        minimumPressDuration = 0
    }
}

但是我已经完全放弃了，因为我已经尝试了大约20种方法，但无法实现。

如何？

最简单的子类将是：

class UITouchyGestureRecognizer: UILongPressGestureRecognizer {
    override init(target: Any?, action: Selector?) {
        super.init(target: target, action: action)
        minimumPressDuration = 0
    }
}

但是如果要使用init（coder ...）然后使用.addTarget(target: Any, action:Selector)

class UITouchyGestureRecognizer: UILongPressGestureRecognizer {
    required init?(coder aDecoder: NSCoder) {
        super.init(target: nil, action: nil)
        print("wth?")
        minimumPressDuration = 0
    }
}
