Question

I’m writing a Navigation-Based iPhone app, and I’d like to have a UIToolBar docked at the bottom of my screen, with a UITableView scrolling between the tool bar and the navigation bar.

I’ve seen a couple of forums where it’s been suggested that the View Controller handling this view should be a standard UIViewController rather than a UITableViewController. The view controller would have to implement the UITableView delegate and data source methods in addition to all of the standard UIViewController overrides. What (if any) built-in functionality do I need to recreate in this view controller subclass other than the aforementioned protocols to have it act like a UITableViewController? Is there anything I’m losing by going this route?

Or would it be better to nest a UITableViewController inside of a standard UIViewController?

As of OS 3.0 the Navigation Controller has a tool bar built in. To make it appear:

[self.navigationController setToolbarHidden:NO];

By implmenting:

- (void)setToolbarItems:(NSArray *)toolbarItems animated:(BOOL)animated

in your view controller, you can configure the items of the tool bar.

So you no longer have to worry about where the tool bar is located in your hierarchy.
