Random ads between cells in a Table View

Question

I’m trying to insert Ads totally random between cells within a UITableView. That’s kind of what I want:

So is mine Table View Controller:

import UIKit
import GoogleMobileAds

class Page1: UITableViewController, UISearchBarDelegate, GADBannerViewDelegate {
    ...
    ...
    ...
    @IBOutlet weak var GoogleBannerView: GADBannerView!

    override func viewDidLoad() {
        super.viewDidLoad()

        self.searchBar.delegate = self
        self.tableView.contentOffset = CGPoint(x: 0, y: searchBar.frame.height) //hide searchBar

        Shared.instance.employees.sort {
            (first, second) in
            first.name.compare(second.name, options: .diacriticInsensitive) == .orderedAscending
        }
    }

    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        if indexPath.row == 3 || indexPath.row == 9 || indexPath.row == 14 {
            let cellAd = tableView.dequeueReusableCell(withIdentifier: "cellAd", for: indexPath)

            GoogleBannerView?.adUnitID = "ca-app-pub-6043248661561548/4628935113"
            GoogleBannerView?.rootViewController = self
            GoogleBannerView?.load(GADRequest())

            return cellAd
        }

        let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! TableViewCell1

        if isSearching {
            cell.nameLabel.text = employeesSearching[indexPath.row].name
            cell.positionLabel.text = employeesSearching[indexPath.row].position
        } else {
            let letter = collation.sectionTitles[indexPath.section]
            let matches = getMatches(letter: letter, withArray: Shared.instance.employees)

            cell.nameLabel.text = matches[indexPath.row].name
            cell.positionLabel.text = matches[indexPath.row].position
        }
        return cell
    }
    ...
    ...
    ...
}

I wish someone could explain to me what I should do at cellForRowAt so that I could add the Ads. Because in the middle of the Indexed sections I’m kind of confused.

EDIT

This is my Tableviewcell class currently:

import UIKit

class TableViewCell1: UITableViewCell {

    @IBOutlet weak var nameLabel: UILabel!
    @IBOutlet weak var positionLabel: UILabel!

}

To insert the Randomic ADS, I indicate that you modify the data array you use to mount the tableview, before displaying the tableview.

For this, Voce could insert the ADS in your data array... or inside the method tableView(tableView: UITableView, numberOfRowsInSection section: Int) together with a variable isAdsAdicionadas; or in some method called by your code BEFORE the numberOfRowsInSection, at the time of instantiation of the screen (I particularly prefer this approach)

From what I saw the array you’re using for this is the matches

So I could do more or less that:

Create attribute isAdsAdicionadas and in the numberOfRowsInSection check variable state, if false, call the method inserirADSRandomicamente:

let isAdsAdicionadas: Bool = false

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

    if(isAdsAdicionadas == false){

        self.inserirADSRandomicamente()
    }

    isAdsAdicionadas = true

    return matches.count
}

func inserirADSRandomicamente(){

    var indiceRandomico: Int!
    var arrayIndiceRandomico:[Int] = []
    let numeroMaximoDeADS = 3
    var contador = 0

    func randomizar(){

        indiceRandomico = Int(arc4random_uniform(UInt32(matches.count)))
        if(contador <= numeroMaximoDeADS){
            if(arrayIndiceRandomico.contains(indiceRandomico) == true){
                randomizar()
            }
            else{
                let objetoADS = "OBJETO ADS"
                matches.insert(objetoADS, at: indiceRandomico)
                arrayIndiceRandomico.append(indiceRandomico)
                contador += 1
                randomizar()
            }
        }
        else{
            return
        }
    }

    randomizar()
}

From there, Voce already has the array with the random ADS. Just treat the cases of being ADS or not, in the method func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell

You can add more logics in the method randomizar(), if you do not want to display two ADS in a row, for example.
