Default How to implement multiple UITableViewCells?

Code:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    if (indexPath.row == 0) {
        return cell0;
    }
    if (indexPath.row == 1) {
        return cell1;
    }
    return cell2;
}
I am getting this error:
UITableView dataSource must return a cell from tableView:cellForRowAtIndexPath:

According to the apple docs this is basically the way to do it. Everything is connected in IB. Any suggestions on what else I should check for?

Thanks,
Dana

What is cell0, cell1, cell2. How are they defined, where are they created?

No, that's not right.

The method tableView:cellForRowAtIndexPath should do the following (in pseudocode)

Code:
Use the row/section to figure out what type of cell to set up
Check for a recycled cell of that type using dequeueReusableCellWithIdentifier
If no recycled cell is available:
{
  create a new, empty cell
  Add any custom subviews or "structural" elements to this cell
}
Now set ALL values for a cell of this type, even if the value for this indexPath is the default

return the cell we just dequeued/created
