please guide above.

thanks in advance.

according me can :

first of assign tag btnpicker , lblseat like

btnpicker.tag = indexpath.row; lblseat.tag = 11111;

then in didselectrow method pickerview assign selected value array.

-(void) pickerview:(uipickerview *)pickerview didselectrow:(nsinteger)row incomponent:(nsinteger)component {     int index = pickerview.tag;     strselected = [numbers objectatindex:row];     nsindexpath *path = [nsindexpath indexpathforrow:index insection:0];      uitableviewcell *cell = [self.tableview cellforrowatindexpath:path];      (uiview* tempview in [cell subviews]) {         if ([tempview iskindofclass:[uilabel class]]) {             if (tempview.tag == 11111) {                 uilabel *lbltemp = (uilabel *)tempview;                 lbltemp.text = strselected;                 break;             }         }     }      self.mpickerview.hidden = true; }

replace pickseats method :

-(void)pickseats:(id)sender {     uibutton *btn = (uibutton *) sender;     self.mpickerview.tag = btn.tag;     self.mpickerview.hidden = false; }

i think work. if not let me know. thnks.
