I have a UITableView which enables multiple selection of rows. I am using the CheckMark accessory to indicate selected rows and also a gradient background.

When I tap a cell the UITableView shows it as selected with the blue gradient and a white checkmark, but when i let go of the tap the checkmark accessory goes to a dark blue colour. 

My question is does anyone know how I can get a white checkmark rather than the blue one.

The reason i need this is that for the selected rows I have a dark blue background and you cannot see the checkmark clearly. I know I can create an image as the accessory view with a white checkmark which is fine, but I just wondered if there was a way to use the inbuilt white checkmark which appears when tapping a row?

Thanks
