super.didreceivememorywarning()         // dispose of resources can recreated.     }  }

so much!

picture of uipicker(no toolbar shows up)

assign toolbar textfield in textfieldshouldbeginediting rather on ibaction. preferencetextclick(_: uitextfield) gets called later , hence, doesn't load toolbar.
