UIView操作-UISwipeGestureRecognizer
[英]UIView action - UISwipeGestureRecognizer
问题描述
I have an action hooked up to a UIView. 
我有一个连接到UIView的动作。 the action was working fine until I turned the alpha of the UIView down to 0. Does anyone know why this might happen or a workaround? 在我将UIView的Alpha值降低到0之前，该操作一直工作良好。有人知道为什么会发生这种情况或解决方法吗？
the action is for a UIView that when swiped with a UISwipeGestureRecognizer performs an action. 该操作适用于使用UISwipeGestureRecognizer滑动时执行操作的UIView。
thanks 谢谢

Alpha值低于特定阈值（0.1左右）的AFAIK视图不会收到触摸事件。
