i have tried , it's no matter on reload datasource.it may problem of data ,i think.

override func viewwillappear(animated: bool) {     super.viewwillappear(animated)      swift_dispatch_after(2, { () -> () in         self.array = nsarray(objects:"a","bb","vcc")         self.tableview.reloaddata()     }); }  // mark: - table view data source override func numberofsectionsintableview(tableview: uitableview) -> int {     return 1 }  override func tableview(tableview: uitableview, numberofrowsinsection section: int) -> int {     return array.count }  override func tableview(tableview: uitableview, cellforrowatindexpath indexpath: nsindexpath) -> uitableviewcell {     let cell = tableview.dequeuereusablecellwithidentifier("reuseidentifier", forindexpath: indexpath) as! uitableviewcell     if array.count != 0 {       let messagedate = nsdate()         let dateformatter = nsdateformatter()         dateformatter.dateformat = "dd-mmm-yyy hh:mm:ss"         let strdate = dateformatter.stringfromdate(messagedate)          cell.textlabel?.text = (array[indexpath.row] as! string) + strdate     }     return cell }
