Loading custom XIB for UITableViewCell

I'm trying to use a custom XIB file for UITableViewCell, but no matter what I do the table cells are always empty - my XIB is simply not loaded.

There are no errors whatsoever.

Here's what I do:

  1. Create an empty application, add a storyboard, table view controller, add a new UITableViewController, hook it up with table and set some sample items.

  2. Create a controller as a subclass of UITableViewCell + check option to generate XIB.

  3. Create three sample labels and add them as IBOutlets.

  4. Load the XIB file and try to set it up as a cell.

Code:

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.tableView.delegate = self;

    items = [[NSMutableArray alloc] init];
    for (int i = 0; i < 20; i++) {
        ItemObject *item = [ItemObject new];
        item.topLabel = [NSString stringWithFormat:@"Top %d", i];
        item.leftLabel = [NSString stringWithFormat:@"Left %d", i];
        item.rightLabel = [NSString stringWithFormat:@"Right %d", i];
        [items addObject:item];
    }
}

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    // Return the number of sections.
    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    // Return the number of rows in the section.
    return items.count;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *cellIdentifier = @"ItemCell";

    // Set up the cell.
    CustomTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier forIndexPath:indexPath];
    if (!cell) {
        [tableView registerNib:[UINib nibWithNibName:@"CustomTableViewCell" bundle:nil] forCellReuseIdentifier:cellIdentifier];
        cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier forIndexPath:indexPath];
    }
    ItemObject *currentObject = [items objectAtIndex:indexPath.row];
    cell.topLabel.text   = currentObject.topLabel;
    cell.leftLabel.text  = currentObject.leftLabel;
    cell.rightLabel.text = currentObject.rightLabel;

    // General cell and table settings.
    [cell setSelectionStyle:UITableViewCellSelectionStyleNone];
    [tableView setSeparatorColor:[UIColor clearColor]];

    return cell;
}

Where the error can be? Can someone point me in the right direction?

Thanks!

Make sure you've set the ItemCell identifier in your XIB and also that your table datasource is set. Then move your registerNib to viewDidLoad

-(void)viewDidLoad {
        //...
       self.tableview.dataSource = self;
       [self.tableView registerNib:[UINib nibWithNibName:@"CustomTableViewCell" bundle:nil] forCellReuseIdentifier:@"ItemCell"];

        }

and the in cellForRowAtIndexPath:

CustomTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"ItemCell" forIndexPath:indexPath];

and remove the if (!cell) block, it won't be used anyway.
