Swift Touch and gesture

Class Myview:uiview {

var lview:uiview!

var time:nstimer!

Override Init (Frame:cgrect) {

Super.init (Frame:frame)

Turn on multi-touch

Self.multipletouchenabled = True

LView = UIView (Frame:cgrect (x:0, y:0, width:50, height:50));

Lview.backgroundcolor = Uicolor.yellowcolor ();

Self.addsubview (LView)

}

Required init? (Coder Adecoder:nscoder) {

Super.init (Coder:adecoder)

}

The method that is called when the click is started

Override Func Touchesbegan (touches:set<uitouch>, withevent event:uievent?) {

println (count)

Got a Uitouch object.

Let Touch:uitouch = Touches.anyobject () as! Uitouch;

Let touch = Touches.first as uitouch!

Get the number of clicks

Let Tapcount = Touch.tapcount;

if (Tapcount = = 1)

{

Click Singletap ()

Using timer delay call

Time = Nstimer.scheduledtimerwithtimeinterval (0.5, target:self, selector: "Singletap", Userinfo:nil, Repeats:false)

}else

{

termination Timer

Time.invalidate ()

Doubletap ()

}

}

Func Singletap () {

Print ("click")

}

Func Doubletap () {

Print ("Double-click")

}

The method that is called when the touch moves

Override Func touchesmoved (touches:set<uitouch>, withevent event:uievent?) {

var touch = Touches.anyobject () as! Uitouch

Let touch = Touches.first as uitouch!

Let location = Touch.locationinview (self)

println ("Location: \ (location.x), \ (LOCATION.Y), \ (location)")

Let lastlocation = Touch.previouslocationinview (self)

println ("Lastlocation: \ (lastlocation.x), \ (LASTLOCATION.Y), \ (lastlocation)")

Let sub = location.x-lastlocation.x

If sub > 0{

Print ("right")

}else If sub < 0 {

Print ("left")

}else {

Print ("Move")

}

Let the small rectangle follow the gesture move Lview.center = Location

LView.frame.origin = Location

}
