ios - Pan UImage within superview swift -


i'm attempting move uiimageview within superview using pan gesture, although i'm able make superview move within self.view not able move 1 of subviews within itself.

these relevant lines in code

let couponoutline = uiview(frame: cgrect(x: 0, y: 0, width: 300, height: 424))  let imageview = uiimageview(image: uiimage(named: "imageplaceholder")) imageview.frame = cgrect(x: 0, y: 0, width: 128, height: 128) imageview.center = cgpoint(x: 230, y: 300)  couponoutline.addsubview(imageview) self.view.addsubview(couponoutline)  let panrec = uipangesturerecognizer(target: self, action: "moveview:")     panrec.minimumnumberoftouches = 1     imageview.addgesturerecognizer(panrec)

in moveview: method

func moveview(sender: uipangesturerecognizer) {      println("pan")      let couponoutline = view.subviews[0] as! uiview      print(couponoutline)      var translation = sender.translationinview(self.view)      sender.view?.center = cgpoint(         x: sender.view!.center.x + translation.x,         y: sender.view!.center.y + translation.y)      sender.settranslation(cgpoint(x: 0, y: 0), inview: couponoutline)

i'm trying move imageview within couponoutline, when use code not pick of gesture @ (println("pan") no shown).
