Passing data from modal navigation controller to parent controller?
<p>I'm starting out in iPhone development, and I'm trying to do a Contacts-style controller to add items to a table. I've got the two controllers designed, but I can't seem to figure out how to pass data between them. How can I get data from the modal controller to its parent?</p>

<p>Just trying to call methods on parentViewController won't work (and results in compiler warnings and crashes). I've considered moving the data out of the controller itself (which is going to happen anyway, I'm just trying to keep things as simple as possible for now), but even then I still have to somehow tell the parent view to refresh its data. Again, how can I do this?</p>
