Hello,

Im trying to open Each vc with each Table View Cell tapped. All I have manged to do is to open one VC with all of Table View Cells. I would like each cell to have open each VC. Here is my code:

RoutesController

import UIKit

class TrasyController: UIViewController,UITableViewDelegate, UITableViewDataSource {
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
            return routes.count
        }
    
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell=tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath as IndexPath) as! TableTableViewCell
        cell.photo.image=self.routesImages[indexPath .row]
        cell.label.text=self.routes[indexPath .row]
        cell.label_car.text=self.czas_auto[indexPath .row]
        cell.label_bike.text=self.czas_rower[indexPath .row]
        cell.label_walk.text=self.czas_pieszo[indexPath .row]
        return cell
    }
    
    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath){
        tableView.deselectRow(at: indexPath, animated: true)
        performSegue(withIdentifier: "1", sender: self)
    } //Here I can perform just one VC form all cells, I need each cell to open each VC (cell with name "one" opens "route1_vc";  cell with name "two" opens "route2_vc" etc.)
    
    
    @IBOutlet weak var tableView: UITableView!
    
    let routes = [("one"),("two"),("three")]
    let routesImages = [UIImage(named: "1.jpeg"), UIImage(named: "2.jpeg"), UIImage(named: "3.jpeg")]
    let czas_auto = [("2h"),("75m"),("2h50m")]
    let czas_rower = [("2h"),("1h25n"),("3h50m")]
    let czas_pieszo = [("2h"),("2h"),("4h50m")]
    let vc = ["route1_vc","route2_vc","route3_vc"]

    override func viewDidLoad() {
        super.viewDidLoad()
        tableView.delegate = self
        tableView.dataSource = self
    }
    
    func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
        return 120
    }

TableTableViewCell:

import UIKit



class TableTableViewCell: UITableViewCell {



    @IBOutlet weak var photo: UIImageView!

    @IBOutlet weak var label: UILabel!

    @IBOutlet weak var label_car: UILabel!

    @IBOutlet weak var label_bike: UILabel!

    @IBOutlet weak var label_walk: UILabel!

    

    

    override func awakeFromNib() {

        super.awakeFromNib()

        // Initialization code

    }



    override func setSelected(_ selected: Bool, animated: Bool) {

        super.setSelected(selected, animated: animated)



        // Configure the view for the selected state

    }



}

Thank you in advance for your help.

You do not yell how your cell type is defined. Is it a subclass of UITableViewCell ? Or a plain UITableViewCell ?

I assume you have defined a subclass to have specific properties, as name.

You could do in several ways:

Create as many segues (from the VC itself) to the different destinations (route1_vc, route2_vc…) and use them:

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath){

    tableView.deselectRow(at: indexPath, animated: true)
    if let cell = tableView.cellForRow(at: indexPath) as? YourCellType {
        
        switch cell.name {
        case "one": performSegue(withIdentifier: "1", sender: self)
        case "two": performSegue(withIdentifier: "2", sender: self)
        default: break
        }
    }
} //Here I can perform just one VC form all cells, I need each cell to open each VC (cell with name "one" opens "route1_vc";  cell with name "two" opens "route2_vc" etc.)

Go directly to the VC:

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath){

    tableView.deselectRow(at: indexPath, animated: true)

    if let cell = tableView.cellForRow(at: indexPath) as? YourCellType {
        let storyboard = UIStoryboard(name: "Main", bundle: nil)
        var destViewController : UIViewController?
        
        switch cell.name {
        case "one": destViewController = storyboard.instantiateViewController(withIdentifier: "route1_vc")

        case "two": destViewController = storyboard.instantiateViewController(withIdentifier: "route2_vc")
        default: return
        }

        if destViewController != nil {
            self.present(destViewController!, animated: true, completion: nil)
        }
    }
} //Here I can perform just one VC form all cells, I need each cell to open each VC (cell with name "one" opens "route1_vc";  cell with name "two" opens "route2_vc" etc.)
