How do I prevent the selection flash when cell selected in a TableView or ListView in iOS?

Hi all,
Im trying to prevent my cells from flashing when they are selected. Ive tried the listView ItemSelected and ItemTapped events to set the SelectedItem back to null, but the selection animation has already occurred. Any way to prevent that?
EDIT: I still want to know when the cell is tapped, I just don't want the animation.

Thanks
John
