How to hide check mark?

[bouchtaoui-dev]

Hello guys, I have a problem to hide the black checkmark on child cells. Everytime I select a child item, it puts a black checkmark on the right of the cell. How can I turn that off? I finally fixed it by commenting out the following line in JKSubTableViewCell.m: cell.selectionIndicatorImg.image = [self selectionIndicatorImgOrDefault];

Is there another better way to do that than the hackish way I did? I rather don't touch the JKExpandTableView project source.
