Question

I’m doing a simples app using Storyboard that a have a View with a UITableView with a UITableViewCell that do the navigation to another UIView.

So a have to code to populate the cell on the table view.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *cellIdentifier = @"SampleCell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];

    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:cellIdentifier];
        NSLog(@"cai no init da cell");
    }

    GPItem *item = [self.items objectAtIndex:indexPath.row];

    cell.textLabel.text = @"Post";
    cell.detailTextLabel.text = item.imageURL;

    return cell;
}

I realised that the code if (cell == nil) { ... never executes so I really need to do that on uses the cell from Storyboard?

Thanks.

You are correct; that code is guaranteed to return a non-nil cell if you are using a storyboard. Also, in iOS 6, the new call dequeueReusableCellWithIdentifier:forIndexPath: never returns nil. See the discussion in my book:
