title: iPhone UITextField within TableCell blanking out
body: <p>In my iPhone app I have a settings page where a user can enter text into multiple TextFields.  The text fields are all cells within a table.  The problem I'm noticing is that when a field scrolls off the phone's screen it loses the value currently in the text field.</p>
  
  <p>I notice Apple's apps always have you click on a field to edit it, which brings up a new view with just that field as a text box.  Seems like pointless extra clicks, I'm hoping to find a way to allow for a table with UITextFields to preserve their values, even when they scroll of screen.</p>
  
  <p>I do have an event bound to when the user presses the Next/Done button on the keyboard (didFinishEditingField:) to update a value within the table controller, but if they don't press that and the just tap inside another field that isn't triggered.</p>
  
  <p>How can I make sure the values aren't blanked out when I scroll the table and fields leave the current screen?</p>
  
  <p><strong>Edit:</strong> For clarification the reason I went with the UITextFields inside of a table and cells, instead of all in one view, is because I wanted it to look like the typical settings page with the stripped background and the groups of inputs.</p>
