  1. Define a delegate protocol, that contains the method - (void)textHasChangedTo:(NSString*)text
  2. Make tableviewcontroller conforming to this protocol.
  3. Implement - (void)textHasChangedTo:(NSString*)text on tableviewcontroller, so that it changes the text in the cell. For Example change the text in your model and let the tableView reloadData.
  4. Define a delegate property on dvc.
  5. Set the delegate of dvc to tableviewcontroller before pushing the dvc onto the navigation stack.
  6. In the button action, call textHasChangedTo: on the delegate with the new text.
