You can't just specify the number of sections, you also have to tell the table view which cells are in which specific sections.

Depending on how you set up -tableView:cellForRowAtIndexPath:, you may only be returning table view cells for one section.

If you don't specify more than one section (via indexPath.section) when creating cells, then you will get an out-of-bounds error in -numberOfSectionsInTableView: if you return more than one section there.

You might post code for -tableView:cellForRowAtIndexPath: so we can see what's going on there. But that would be the first place I would look.
