i'm new in swift programming . i'm trying features of textfield . want show textfields value in uitableview. stuck in code please check out .... , give solution

 import uikit   class langviewcontroller: uiviewcontroller {  var txt = ""  let simpletableidentifier = "tableviewcell";  @iboutlet weak var txtlang: uitextfield!   @iboutlet weak var langtableview: uitableview!   override func viewdidload() {  super.viewdidload()     }   override func didreceivememorywarning() {   super.didreceivememorywarning()    }  @ibaction func addbuttontapped(sender: anyobject)  {  txt = txtlang.text   self.langtableview.reloaddata()    langdata.append(txt)   print(langdata)   txtlang.resignfirstresponder()     }      func tableview(tableview: uitableview!,                      cellforrowatindexpath indexpath: nsindexpath!) -> uitableviewcell! {     let cell = tableview.dequeuereusablecellwithidentifier(simpletableidentifier) uitableviewcell      cell.textlabel?.text = txt      return cell;   } 

to update table view cells have call reloaddata(). have this:

1. declare txt variable right class definition starts:

var txt = "" 

2. in button handler call reloaddata() update cells.

@ibaction func addbuttontapped(sender: anyobject) {     txt = txtlang.text     self.tableview.reloaddata() } 

3. set text cell's label:

func tableview(tableview: uitableview!, cellforrowatindexpath indexpath: nsindexpath!) -> uitableviewcell! {     let cell = tableview.dequeuereusablecellwithidentifier(simpletableidentifier) as! uitableviewcell      cell.textlabel?.text = txt      return cell; }
