There is a property adjustImageWhenHighlighted which is simply

"A Boolean value that determines whether the image changes when the button is highlighted."

Straight from the library. You can set that to NO for your UIButton in your selectedRow method, and if your action for that button is being accessed, you can set that in there too following @madhu's instructions on setting up the action when it is touched.

Haven't actually tried it, since usually when I have a custom UITableViewCell, I simply subclass it and add all subviews in that subclass.

Also, remember to release allocations.
