    For a tab bar app with nav controllers how can i get any data from a details view controller like input in any text field, date value in a date picker etc when user clicks on/Done Back button on nav bar.
    Do I need to implement any kind of delegate or does there exists any other way to do this?

    - (BOOL)textFieldShouldReturn:(UITextField *)textField;
