简单地继承 UITouchGestureRecognizer，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
    }
}

但是我已经彻底放弃了，因为我试了大概20种方法都搞不定

怎么办？

最简单的子类是：

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

但是如果你想使用 init(coder...) 然后 .addTarget(target: Any, action:Selector)

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