How to use didSelectRowAtIndex?

Question

I would like to know how to use didSelectRowAtIndex, more specifically I would like to know how each Row of my UITableView calls a ViewController specifies. In my code below, in case would like each item of the array who is in the UITableView call another ViewController.

class ViewControllerAnalise: UIViewController, UITableViewDataSource, UITableViewDelegate {
    var formulas = ["Participaçao de Capital de Terceiros", "Composiçao do Endividamento", "Imobilizaçao do Patrimonio Liquido", "Liquidez Geral", "Liquidez Corrente", "Liquidez Seca", "Giro do Ativo", "Margem Liquida", "Rentabilidade do Ativo", "Rentabilidade do PL"]

    override func viewDidLoad() {
        super.viewDidLoad()
    }

    func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        var cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as! ViewControllerCell2

        cell.formula.text = formulas[indexPath.row]

        return cell
    }

    func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return formulas.count
    }
}

Eduardo, it’s very simple but it also depends on how your structure is. The way you explained it is pretty shallow, so I’m gonna make some assumptions.

To do this, all you have to do is identify which cell is pressed and tell which screen will be opened for each situation.

It would look like this, for example:

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    var viewController: UIViewController

    switch indexPath.row {
    case 0: viewController = ParticipacaoCapitalViewController()
    case 1: viewController = ComposicaoViewController()
    case 2: viewController = ImobilizacaoViewController()
    default: viewController = nil
    }

    if viewController != nil
        navigationController?.pushViewController(viewController, animated: true)
}

Here too I’m guessing you’re using UINavigationController, therefore the pushViewController, otherwise it will be necessary to open otherwise.
