ios - How can I change the colour behind the UITableViewCell while editing? -

i have standard uitableviewcell backgroundcolor property set differently tableview backgroundcolor. can see in image, part of cell on overshoot when editing, not coloured (white).

i've tried setting the

• cell.backgroundcolor • cell.contentview.backgroundcolor • cell.backgroundview uiview() set backgroundcolor 

nothing seems work :( tableview cannot colour due alternating colour cells (white, offwhite, etc.)

edit: tableview must remain white due potentially not being full , matching ui.
