Striping Rows of a UITableView

I've read posts here on SO about striping a UITableView's cells, but have not been able to work out the details. My code is:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    // Setup code omitted

    cell.textLabel.text = @"Blah Blah";
    cell.detailTextLabel.text = @"Blah blah blah";
    cell.accessoryType = UITableViewCellAccessoryDisclosu开发者_C百科reIndicator;
    if ([indexPath row] % 2 == 1) {
        cell.contentView.backgroundColor     = [UIColor colorWithRed:0.9 green:0.9 blue:0.9 alpha:1.0];
        cell.textLabel.backgroundColor       = [UIColor colorWithRed:0.9 green:0.9 blue:0.9 alpha:0.0];
        cell.detailTextLabel.backgroundColor = [UIColor colorWithRed:0.9 green:0.9 blue:0.9 alpha:1.0];
        cell.accessoryView.backgroundColor   = [UIColor colorWithRed:0.9 green:0.9 blue:0.9 alpha:1.0];
    }
    return cell;
}

And my result is:

Any ideas why this is happening? Thanks!

These cells get reused, you should set it back to normal in the case of [indexpath row] % 2 == 0

 - (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {
         [cell setBackgroundColor: indexPath.row % 2 == 0 ? color1 : color2];

}
