Adding Custom Selection Traits
When a user selects a cell, Cocoa Touch helps you emphasize the cell’s selection. Customize a cell’s selection behavior by updating its traits to stand out from its fellows. There are two ways to do this.
The selectedBackgroundView property allows you to add controls and other views to just the currently selected cell. This works in a similar manner to the accessory views that appear when a keyboard is shown. You might use the selected background view to add a preview button or a purchase option to the selected cell.
The cell label’s highlightedTextColor property lets you choose an alternative text color when the cell is selected.
