iPhone - didPopItem ? Is this supposed to work?

I have a simple UITableView setup. I am trying to use

- (void)navigationBar:(UINavigationBar *)navigationBar didPopItem:(UINavigationItem *开发者_如何学C)item

I put a NSLog inside this method, but it is apparently not getting called when I "pop" back to the screen. I am not finding much information about this function, has it been replaced?

Have you set your table view controller as the navigation bar's delegate?
