UITableView dataSource must return a cell from tableView:cellForRowAtIndexPath error

I am getting that error with this piece of code. Can you help me figure out why.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"CustomerCell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    Restaurant *restaurant = [self.restaurants objectAtIndex:[indexPath row]];
    [[cell textLabel] setText:[NSString stringWithFormat:@"%@ %@",restaurant.Name,restaurant.Address]];
    return cell;
}

The problem with your code is that dequeueReusableCellWithIdentifier: does not always return you a valid cell; sometimes, it returns nil. In such cases you need to allocate a new instance of your cell, and then initialize it the usual way. As it currently stands, your method would return nil if one is returned from the dequeueReusableCellWithIdentifier: method.

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (!cell) {
      cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyle1 reuseIdentifier:CellIdentifier];
}
