iphone connecting code to the 'back' button
<p>Is there a way to connect code to a view's 'back' button that is part of a navigation controller?  That back button is automatically coded in by the nature of it being a navigation controller so I am not sure how I can connect code to it.</p>

<p>(I know this should be really easy but I can't seem to find it in the documentation on navigation controller.)</p>
