How to cancel selection in a UITableView?

After an hour trying to fix this problem I was finally able to solve my problem, which I had to be:

let esVisitadoTitulo = (esVisitado[indexPath.row]) ? "Seleccionar" : "deseleccionar"
let esVisitadoAction = UIAlertAction(title: esVisitadoTitulo, style: .Default, handler: {

let cell = tableView.cellForRowAtIndexPath(indexPath)
            cell?.accessoryType = .Checkmark
            self.Visitado[indexPath.row] = (self.Visitado[indexPath.row]) ? false : true;
            cell?.accessoryType = (self.Visitado[indexPath.row]) ? .Checkmark : .None

Now when you select something it asks you Seleccionarand if you want deseleccionaryou have to tap again and select Deseleccionar. I still haven't been able to find a way to be able to deselect, when the user taps on the device 2 times.

Here's how you could do it by following best practices like creating a model for the data you put in the TableView:

import UIKit

class MyObject {
    var title = ""
    var selected = false

    init(title: String) {
        self.title = title
    }
}

class ViewController: UITableViewController {
    var visitados = []

    override func viewDidLoad() {
        super.viewDidLoad()

        let object1 = MyObject.init(title: "Título 1")
        let object2 = MyObject.init(title: "Título 2")
        let object3 = MyObject.init(title: "Título 3")

        visitados = [object1, object2, object3]
    }

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

    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
    {
        let object = visitados[indexPath.row] as! MyObject
        let cell = tableView.dequeueReusableCellWithIdentifier("MyCell", forIndexPath: indexPath)

        cell.textLabel?.text = object.title
        cell.accessoryType = (object.selected) ? .Checkmark : .None

        return cell
    }

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

        let object = visitados[indexPath.row] as! MyObject
        let cell = tableView.cellForRowAtIndexPath(indexPath)

        if object.selected {
            cell!.accessoryType = .None
            object.selected = false
        }
        else {
            cell!.accessoryType = .Checkmark
            object.selected = true
        }

        tableView.deselectRowAtIndexPath(indexPath, animated: true)
    }
}

In this case it MyObjectwould represent each data you want to put in the TableView. I have only defined a title and its status, to know if it is selected or not. It is fully functional.

Making it modular allows you to better organize your code and make it more readable. Whenever possible, use this type of pattern when creating your applications.

Here is the code for one tap and two taps. What you have to do is tell it how many times it is necessary to press withnumberOfTapsRequired

let t2 = UITapGestureRecognizer(target:self, action:"PulsacionDoble")
        t2.numberOfTapsRequired = 2
        self.v.addGestureRecognizer(t2)

        let t1 = UITapGestureRecognizer(target:self, action:"PulsacionSimple")
        t1.requireGestureRecognizerToFail(t2)
        self.v.addGestureRecognizer(t1)

         func PulsacionDoble() {
        print("Pulsacion Simple")
    }
    func PulsacionSimple() {
        print("Pulsacion Doble")
    }
