Binding JSON data to TableView and CollectionView

Question

I am trying to create a table view with a collection view in each cell. My JSON structure is like Main Menu title for the tv cell and in each main object, I receive a submenu, whose data I want to use in the collection view.

The issue I am facing is in using indexes of table cell and collection cell to get the nested data. Here is my JSON

  "MainMenu": [
    {
      "ID": 8,
      "MasterID": 12,
      "Title": "Payment",
      "Image": "image.png",
      "SubMenu": [
        {
          "ID": 9,
          "Title": "My Bill",
          "Image": "image.png"
        },
        {
          "ID": 10,
          "Title": "Electricity ",
          "Image": "image.png"
        },
        {
          "ID": 11,
          "Title": "Gas",
          "Image": "image.png"
        },
        {
          "ID": 12,
          "Title": "Telephone",
          "Image": "image.png"
        },
        {
          "ID": 13,
          "Title": "Water",
          "Image": "image.png"
        }
      ]
    },

        }
      ]
    }
  ],
  "CustomerAccountInformation": []
}

Please guide me how can I use my JSON objects each in different tablecell. Here is what I have tried:

TVCell
cell.titleLabel.text = menu?.mainMenu?[indexPath.row].title ?? "Our services"

CollectionCell
cell.image.af_setImage(withURL: URL.init(string: (menu?.mainMenu?[indexPath.row].subMenu?[indexPath.row].image)!)!)

Answer 1

First, in your tableview cell, set the tag of the collectionview to indexPath.row

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell : TVCell = tableview.dequeueReusableCell(withIdentifier: "TVCell", for: indexPath) as! TVCell
cell.myCollectionView.tag = indexPath.row
    return cell
}

Now in your collectionview cell you can parse the data like following

let index = cell.tag
cell.image.af_setImage(withURL: URL.init(string: (menu?.mainMenu?[index].subMenu?[indexPath.row].image)!)!)
