iPhone, how can I make my UITableView cells black with and without data in them?

I'm managed to make my UITableView rows / cells black when data is loaded, to a fashion, I get a white line in between rows, which makes it look awful. How can i make them fully black with and without data ?

Heres the code I'm using at the moment

- (void)tableView:(UITableView *)tableView willDisplayCell:
        (UITableViewCell *)cell forRowAtIndexPath:(NS开发者_Go百科IndexPath *)indexPath {
cell.backgroundColor = [UIColor blackColor];

}

Heres what I get (with white lines remaining) :(

Change the separator style of your table view.

yourTableView.separatorStyle = UITableViewCellSeparatorStyleNone;

You can do it in Interface Builder too on the properties palette.

-- Edit for clarity following comments below --

Set the entire tableView to have a black background:

[yourTableView setBackgroundColor:[UIColor blackColor]];

This can also be done in the Interface Builder properties panel.
