I am having issues setting the cell background colour on a grouped table cell when in edit mode. It seems to get the checkmark to appear a selection style has to be set and the only options are UITableViewCellSelectionStyleBlue or UITableViewCellSelectionStyleGray.
What I am after is the for the checkmark just to be selected and the cell remain white when it is checked.
You would have thought UITableViewCellSelectionStyleNone would have this behaviour but this stops the checkmark for showing.

I have tried to use setSelectedBackgroundView. This would work if the cell style was not grouped but as it is the round corners do not get drawn.

The properties for the cell above are
cell.selectionStyle = UITableViewCellSelectionStyleGray;
cell.backgroundView = [self tableViewCellRowBackground];
Where tableViewCellRowBackground is a UIView with orange background.
The editMode is the built in iOS table edit mode with the following properties set on the table
self.tblFiles.allowsSelectionDuringEditing=YES;
self.tblFiles.allowsMultipleSelectionDuringEditing = YES;
Any ideas?
In the end I had to create my own custom cells by overriding the drawrect method.
