indexPath.row有更短的使用方法吗？

Question

有没有更短的方法来使用indexPath.row？我现在正在使用这个：

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {

    if indexPath.row == 0 {

        self.performSegueWithIdentifier("0", sender: self)
        tableView.deselectRowAtIndexPath(indexPath, animated: true)

    } else if indexPath.row == 1 {

        self.performSegueWithIdentifier("1", sender: self)
        tableView.deselectRowAtIndexPath(indexPath, animated: true)

    } else if indexPath.row == 2 {

        self.performSegueWithIdentifier("2", sender: self)
        tableView.deselectRowAtIndexPath(indexPath, animated: true)

    } else if indexPath.row == 3 {

        self.performSegueWithIdentifier("3", sender: self)
        tableView.deselectRowAtIndexPath(indexPath, animated: true)

    } else if indexPath.row == 4 {

        self.performSegueWithIdentifier("4", sender: self)
        tableView.deselectRowAtIndexPath(indexPath, animated: true)

    } else if indexPath.row == 5 {

        self.performSegueWithIdentifier("5", sender: self)
        tableView.deselectRowAtIndexPath(indexPath, animated: true)

    } else if indexPath.row == 6 {

        self.performSegueWithIdentifier("6", sender: self)
        tableView.deselectRowAtIndexPath(indexPath, animated: true)

    } else if indexPath.row == 7 {

        self.performSegueWithIdentifier("7", sender: self)
        tableView.deselectRowAtIndexPath(indexPath, animated: true)

    } else if indexPath.row == 8 {

        self.performSegueWithIdentifier("8", sender: self)
        tableView.deselectRowAtIndexPath(indexPath, animated: true)

    } else if indexPath.row == 9 {

        self.performSegueWithIdentifier("9", sender: self)
        tableView.deselectRowAtIndexPath(indexPath, animated: true)

    } else if indexPath.row == 10 {

        self.performSegueWithIdentifier("10", sender: self)
        tableView.deselectRowAtIndexPath(indexPath, animated: true)

    }
}

实际上我在项目中使用了 42 条 indexPath.row 语句，但我只举了上面的 11 条作为示例。

你可以这样做

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    self.performSegueWithIdentifier(String(indexPath.row), sender: self)
    tableView.deselectRowAtIndexPath(indexPath, animated: true)
}

indexPath.row有更短的使用方法吗？

Is there a shorter way to use indexPath.row?
