Have you tried to use session variables? You can store all the fields in session vars and everytime a user visits that page, it will first check to see if the session vars are set. If so, render the form with those input fields pre-populated with the session var values. If not, then render a blank form.
You may consider storing the contents of the text field to an NSString * instance variable of your application delegate. The best place to do so would be viewDidUnload method, provided that you did retain the text field.
