  let me explain first
  in my table view each cell have some value when  tableview is drown fist time this all value is coming from database.
  then later through didselectedRowAtIndexPath for example  i select first cell value and take it in label in another view and change it a when i click save button on new view then my new value is coming back in first view in table view cell correctly this all operation is correctly working. </p>
