ios - touchesBegan called many times -

-

i have strange issue touchesbegan handler being called more necessary. if tapped uiview (uibutton) fast 2 times, touchesbegan called 3 times.

i solved issue simple time measurement still interested reason kind of behaviour?

here code (with added time-checking):

override func touchesmoved(touches: nsset, withevent event: uievent) {     if let t:uitouch = touches.anyobject() as? uitouch     {         if !cgrectcontainspoint(cgrectmake(0, 0, self.frame.width, self.frame.height), t.locationinview(self))         {             touchescancelled(touches, withevent: event)         }     } }  override func touchesbegan(touches: nsset, withevent event: uievent) {     forcanceltouch = false     setupbuttongui(true) }  override func touchesended(touches: nsset, withevent event: uievent) {     if !forcanceltouch     {         if abs(lastvalidtouchesbegandate.timeintervalsincenow) > delaybetweenfasttapping         {             nsnotificationcenter.defaultcenter().postnotificationname(sbdcnotificationnameactionstbmakeonecommand, object: self, userinfo: ["tag":self.tag])             lastvalidtouchesbegandate = nsdate()         }     }     setupbuttongui(false) }  override func touchescancelled(touches: nsset!, withevent event: uievent!) {     forcanceltouch = true     setupbuttongui(false) }

well - seems issue happens when clicking/testing mouse inside ios simulator! looks ios simulator bug.
