override var showSubrowsInRow: Int? {
return someValue
}
override func tableView(_ tableView: UITableView, cellForRow row: Int, indexPath: IndexPath) -> UITableViewCell {
if row == self.nsk_selectedRow {
someCell.accessoryView = UIImageView(image: UIImage(named: "up_arrow"))
} else {
someCell.accessoryView = UIImageView(image: UIImage(named: "down_arrow"))
}
return someCell
}
override func tableView(_ tableView: UITableView, cellForSubrow subrow: Int, inRow row: Int, indexPath: IndexPath) -> UITableViewCell {
return someCell
}
override func tableView(_ tableView: UITableView, didSelectRow row: Int) {
switch (self.nsk_selectedRow, row) {
case (let sr?, _) where row == sr:
tableView.cellForRow(at: row)?.accessoryView = UIImageView(image: UIImage(named: "down_arrow"))
tableView.deselect(row: row, animated: true)
break
case (let sr?, _) where row != sr:
tableView.cellForRow(at: row)?.accessoryView = UIImageView(image: UIImage(named: "up_arrow"))
tableView.cellForRow(at: sr)?.accessoryView = UIImageView(image: UIImage(named: "down_arrow"))
break
case (nil, _):
tableView.cellForRow(at: row)?.accessoryView = UIImageView(image: UIImage(named: "up_arrow"))
break
default:
break
