Answer 2

you need to first set button tag in cellForRow method
after in didSelectRowAtIndexPath method you need to set image of button and in didDeselectRowAtIndexPath set unselect image in button.
you can set button image by using :
playButton.setImage(UIImage(named: "play.png"), forState:UIControlState.Normal)

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
guard let btn = (tableView.cellForItem(at: indexPath) as! yourCellName).button else {
return
}
btn.setImage(UIImage(named: "yourSelectedImage name"), for: .normal)
}
func tableView(_ tableView: UITableView, didDeselectRowAt indexPath: IndexPath) {
guard let btn = (tableView.cellForItem(at: indexPath) as! yourCellName).button else {
return
}
btn.setImage(UIImage(named: "yourNotSelectedImagename"), for: .normal)
}
