Swift uses the Touchesbegan method to obtain a user-clicked view, simulating a continuous click effect

var MV:uiview!

override func viewdidload () {

Super. Viewdidload()

MV = UIView (frame: cgrect (x: +, y: + , Width: + , Height: )) /c12>

MV. BackgroundColor = uicolor. Red

Self . view. Addsubview (mV)

}

var flag = false

override Func Touchesbegan (_ Touches: set<uitouch>, with event: uievent?) {

For touch:anyobject in touches{

Method One

//Get user-clicked coordinates

var point = (touch as Anyobject). Location (In:self.view)

The point coordinates of the user's click, from Self.view.layer to MV.View.layer.

Point = Self.mV.layer.convert (point, From:self.view.layer)

Print ("point\ (point)")

//

Let Point2 = Self.mV.layer.convert (point, To:self.view.layer)

Print ("point2\ (Point2)")

//

if Self.mV.layer.contains (point) {

print (1)

//            }

//Method two

//Get user-clicked coordinates

var point = (Touch as anyobject). location at: Self. View)

Returns the farthest descendant of the View.layer that contains point in the layer hierarchy, that is, gets the layer of the view to which the user clicked

Let layer = view. Layer. hitTest (point)

if layer = = MV. layer{

//Simulate online click Effect

Let t:Uitouch = Touch as! uitouch

Let i = T.tapcount

if T.tapcount >= 2{

flag = true

}

if flag{

print (i)

}

}

}

flag = false

}
