ios - Multiple touches on UIButton with Swift? -


i trying count number of fingers touches button @ same time.

i tap 1 time: +1, tap 2 fingers: +2, tap 3 fingers: +3 , on...

what have:

var count = 0; @ibaction func ontap(sender: uibutton) {     count++; }

the "ontap" function however, fires 1 time if touch button multiple fingers.

how track number of fingers button has been touched with?

import uikit class viewcontroller: uiviewcontroller {     @iboutlet weak var bigbutton: uibutton!     override func viewdidload() {         super.viewdidload()         let onefingertap = uitapgesturerecognizer(target: self, action:"onefingertapdetected:")         onefingertap.numberoftouchesrequired = 1         let twofingertap = uitapgesturerecognizer(target: self, action:"twofingertapdetected:")         twofingertap.numberoftouchesrequired = 2         let threefingertap = uitapgesturerecognizer(target: self, action:"threefingertapdetected:")         threefingertap.numberoftouchesrequired = 3         bigbutton.addgesturerecognizer(onefingertap)         bigbutton.addgesturerecognizer(twofingertap)         bigbutton.addgesturerecognizer(threefingertap)     }     override func didreceivememorywarning() {         super.didreceivememorywarning()     }     func onefingertapdetected(sender:uitapgesturerecognizer) {         println("one")     }     func twofingertapdetected(sender:uitapgesturerecognizer) {         println("two")     }     func threefingertapdetected(sender:uitapgesturerecognizer) {         println("three")     } }
