More than 1 year has passed since last update.

デモ

デフォルト

func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
    if editingStyle == .delete {
        array.remove(at: indexPath.row)
        tableView.deleteRows(at: [indexPath], with: .fade)
    }
}

ボタンの文字や背景色を変えたい場合

func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {

    let deleteButton: UITableViewRowAction = UITableViewRowAction(style: .normal, title: "削除") { (action, index) -> Void in
        self.array.remove(at: indexPath.row)
        tableView.deleteRows(at: [indexPath], with: .fade)
    }
    deleteButton.backgroundColor = UIColor.red

    return [deleteButton]
}
