ok, think answer own question, , easy. create custom view controller file , associated tabbar view on history board , add action uibuttonbaritem this:

import uikit  class customtabbarviewcontroler: uitabbarcontroller {       @ibaction func showactionsheet(sender: uibarbuttonitem) {          let myactionsheet = uialertcontroller(title: "log in", message: "how want log in", preferredstyle: uialertcontrollerstyle.actionsheet)          let fbloginbutton = uialertaction(title: "facebook", style: uialertactionstyle.default)             { (action) in                 print("facebook button tapped")         }         let googleplusbutton = uialertaction(title: "google plus", style: uialertactionstyle.default) {             (action) in             print("google plus button tapped")         }         let twitterbutton = uialertaction(title: "twitter", style: uialertactionstyle.default) {             (action) in             print("twitter button tapped")         }          let cancelbutton = uialertaction(title: "cancel", style: uialertactionstyle.cancel) {             (action) in             print("cancel button tapped")         }          myactionsheet.addaction(fbloginbutton)         myactionsheet.addaction(googleplusbutton)         myactionsheet.addaction(twitterbutton)         myactionsheet.addaction(cancelbutton)          self.presentviewcontroller(myactionsheet, animated: true, completion: nil)     }  }

and works fine me.
