var cancelbtn = uibarbuttonitem(title: "cancel", style: uibarbuttonitemstyle.plain, target: self, action: "closesettings") self.navigationitem.hidesbackbutton = true self.navigationitem.leftbarbuttonitem = cancelbtn

if don't have self.navigationitem.hidesbackbutton = true line in place, button arrow still appears. line in code, button hidden , cancel button appears how want. problem coming when open view controller cell, button not present. instantiate view controller when cell clicked, , use navigation controller push view controller. have attempted put

self.navigationitem.hidesbackbutton = false

in code right before pushviewcontroller(). when see button appear, when new view controller pushed on navigation controller, button disappears.
