ios - different methods on one standard headCell in func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell{ -

i have 2 tableviews in same view controller: "studentstable" , "professorstable". wanted create standard head cell both tables. subclassed uitableviewcell , created headcell type. assigned 1 headcell both if indexpath.row==0. went smooth, however, there 1 problem. whenever click "addingbutton" want "addstudent" function called if on "studentstable" , "addprofessor" if on "professorstable". can create 2 headcells, 1 each of tables wonder if there more professional way of handling writing less code. here code suppose may work if right "if" condition given. in advance

 func tableview(tableview: uitableview, cellforrowatindexpath indexpath: nsindexpath) -> uitableviewcell{    var actiontype:string=string()    if(/*what condition should put?*/)     {actiontype="addstudent"}    else    {actiontype="addprofessor"}       if(indexpath.row==0)            {                var theheadcell : headcell = tableview.dequeuereusablecellwithidentifier("headcell") headcell             // cell setup               if(actiontype != "")                 {                    addbutton.addtarget(self, action: nsselectorfromstring(actiontype), forcontrolevents: uicontrolevents.touchupinside)                 }               return theheadcell            }      else      {          if (tableview==self.studentstable)              {                  var cell : uitableviewcell = tableview.dequeuereusablecellwithidentifier("studentscell") uitableviewcell                    // cell setup                   return cell              }         else             {                     var cell : uitableviewcell = tableview.dequeuereusablecellwithidentifier("professorscell") uitableviewcell                  // cell setup                 return cell            }     }         } 

if tableview == self.studentstable     {actiontype = "addstudent"} else if tableview == self.professorstable    {actiontype = "addprofessor"}
