Answer 1

All you need to do is add the following code in your table's view controller implementation file.

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {
if (indexPath.row%2 == 0) {
    UIColor *altCellColor = [UIColor blackColor];
    cell.backgroundColor = altCellColor;
}}

It's then as simple as adding and changing the modulus values.
