you can hide menu button setting nill in viewdidload

self.navigationitem.leftbarbuttonitem = nil; 

store controller identity in userdefault(sidemenu , tabbar) like

//leaving side menu account   userdefaults.standard.set("side", forkey: "menubutton")  //leaving side menu account userdefaults.standard.set("tab", forkey: "menubutton") 

when view disappear , check menubutton key in myaccount , show/hide menu button like

let controllername = userdefaults.standard.value(forkey: "menubutton")  if (controllername == "side") { } else { self.navigationitem.leftbarbuttonitem = nil; }
