Specifying Segue for UITableViewCell - ios

Question

I have a collection of items I'm putting into a menu for the time being while I work out my layout planning but I am having trouble with figuring out how to work the DidSelectRow with the indexPath.row -
I have the following code:
import UIKit
class DispatchViewController: UIViewController {
#IBOutlet weak var tableView: UITableView!
var videos: [DispatchMenuItem] = []
override func viewDidLoad() {
super.viewDidLoad()
videos = createArray()
self.tableView.rowHeight = 65.0
tableView.dataSource = self
}
func createArray() -> [DispatchMenuItem] {
let video1 = DispatchMenuItem(image: #imageLiteral(resourceName: "truckUnloadIcon"), title: "Open Manifests")
let video2 = DispatchMenuItem(image: #imageLiteral(resourceName: "podIcon"), title: "Customer Pickup")
return [video1, video2]
}
}
extension DispatchViewController: UITableViewDataSource, UITableViewDelegate {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return videos.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let video = videos[indexPath.row]
let cell = tableView.dequeueReusableCell(withIdentifier: "DispatchMenuItemCell") as! DispatchMenuItemCell
cell.setVideo(video: video)
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
print(indexPath.row)
print(indexPath)
if indexPath.row == 1{
self.performSegue(withIdentifier: "goToOpenManifests", sender: nil)
}else if indexPath.row == 2{
self.performSegue(withIdentifier: "goToCustomerPickupForm", sender: nil)
}
}
}
You can see near the bottom my DidSelectRow, but it doesn't want to print out the indexPath.row so I am assuming that the row being selected is somehow now being passed along through the extension.
Are there any suggestions? I've usually done this through just a UITableViewController and have never had this issue, but somewhere here I seem to be getting stuck.

Answer 1

It will not print out the indexPath as you have not set the delegate. Implementing just the method is not sufficient, tableView needs to know who is going to implement the delegate methods.
There is a difference between delegate and datasource.
tableView.dataSource will help you to fetch numberofSections, numberofRowsInASection, TableCell Object
tableView.delegate will help you to manage the selection and deselection.
override func viewDidLoad() {
super.viewDidLoad()
videos = createArray()
self.tableView.rowHeight = 65.0
tableView.dataSource = self
//Add this
tableView.delegate = self
}

Answer 2

You just need to add below the first line of code in viewDid load method and improve your code like below.
tableView.delegate = self
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
print(indexPath.row)
print(indexPath)
if indexPath.row == 0 {
self.performSegue(withIdentifier: "goToOpenManifests", sender: nil)
}else if indexPath.row == 1 {
self.performSegue(withIdentifier: "goToCustomerPickupForm", sender: nil)
}
}
