{
    return [recipes count];
}

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

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];

    if (cell == nil) {

You can set up tag (for example 100) to the label in storyboard and in cellForRowAtIndexPath: method before you return cell you cat get reference to that label by tag

UILabel *taggedLabel =(UILabel*) [cell.contentView viewWithTag:100]; 
taggedLabel.text = [recipes objectAtIndex:indexPath.row];

When you add a label to your prototype cell, and wish to access that label through your code, you need to do the following as well:

  • Define a class for your custom cell, extending UITableViewCell
  • Add an IBOutlet property txtname for your label in the custom cell class
  • Establish a connection between the outlet property and the label (e.g. by command-dragging)
  • Set the type of your custom cell to the properties of your prototype cell in the storyboard
  • Change the code to reference your custom cell type instead of UITableViewCell

The last step changes your code as follows:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *simpleTableIdentifier = @"RecipeCell";
    MyCustomTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
    if (cell == nil) {
        cell = [[MyCustomTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
    }
    cell.txtname.text = [recipes objectAtIndex:indexPath.row];
    return cell;
}
