UITableViewCell traverses through all its descendant views and adjusts their background color accordingly either to [UIColor clearColor], although potentially it could use the same color as the selection highlight itself. After selection, the same trick is performed again in reverse, putting all the backgrounds back as they used to be. But in our case, we don't want to have the background color disappearing so we reset it after highlighting or selection is done.
