Swift custom UIView click-Through

Write a custom view in the morning and find a magical problem, because it's really magical, so just record

Generally, when we customize the view, we like to write this:

Override Init (frame:cgrect) {        super.init (frame:frame)        //Add other views        

In this way, the created view will not have a penetrating click effect.

However, there is an interface for drawing graphics:

Override func DrawRect (rect:cgrect) {     //Add other views     Self.addsubview (view1)            }

By calling this way, you will find that clicking on the drawn view will affect the parent view.

It's almost.
