Getting the TableView Section Title from TableViewCell, swift - ios

Question

I have a TableView with two kind of Cells, both are filled with a CollectionView. In the TableViewController I let them them display with a simple if Statement.
My TableViewController:
import UIKit
import RealmSwift
import Alamofire
import SwiftyJSON
let myGroupLive = DispatchGroup()
let myGroupCommunity = DispatchGroup()
class HomeVTwoTableViewController: UITableViewController {
var headers = ["Live", "Channel1", "ChannelTwo", "Channel3", "Channel4", "Channel5", "Channel6"]
override func viewDidLoad() {
super.viewDidLoad()
DataController().fetchSomeDate(mode: "get")
DataController().fetchSomeOtherData(mode: "get")
}
//MARK: Custom Tableview Headers
override func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
return headers[section]
}
override func tableView(_ tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int){
view.tintColor = UIColor.black
let header = view as! UITableViewHeaderFooterView
if section == 0 {
header.textLabel?.textColor = UIColor.black
view.tintColor = UIColor.white
}
else {
view.tintColor = UIColor.groupTableViewBackground
}
}
//MARK: DataSource Methods
override func numberOfSections(in tableView: UITableView) -> Int {
return headers.count
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 1
}
//Choosing the responsible PrototypCell for the Sections
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if indexPath.section == 0 {
let cell = tableView.dequeueReusableCell(withIdentifier: "cellBig", for: indexPath) as! HomeVTwoTableViewCell
return cell
}
else if indexPath.section == 1 {
let cell = tableView.dequeueReusableCell(withIdentifier: "cellSmall", for: indexPath) as! HomeVTwoTableViewCellSmall
return cell
}
else {
let cell = tableView.dequeueReusableCell(withIdentifier: "cellSmall", for: indexPath) as! HomeVTwoTableViewCellSmall
return cell
}
}
//Set custom cell height, has to match the CollectionView height
override func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
if indexPath.section == 0 {
return 225.0
}
else {
return 120.0
}
}
}
My TableViewCellSmall:
import UIKit
import RealmSwift
var communities: Results<Community>?
class HomeVTwoTableViewCellSmall: UITableViewCell{
#IBOutlet weak var collectionView: UICollectionView!
}
extension HomeVTwoTableViewCellSmall: UICollectionViewDataSource,UICollectionViewDelegate {
//MARK: Datasource Methods
func numberOfSections(in collectionView: UICollectionView) -> Int
{
return 1
}
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int
{
return (communities?.count)!
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell
{
guard let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "collectionCellSmall", for: indexPath) as? HomeVTwoCollectionViewCellSmall else
{
fatalError("Cell has wrong type")
}
//Here I want my Sorting Statement to make unique content per collection view
//normal approach if no section is asked
let url : String = (communities?[indexPath.row].pictureUri)!
let name :String = (communities?[indexPath.row].communityName)!
cell.titleLbl.text = name
cell.imageView.downloadedFrom(link :"somelink")
return cell
}
//MARK: Delegate Methods
override func layoutSubviews() {
myGroupCommunity.notify(queue: DispatchQueue.main, execute: {
let realm = try! Realm()
communities = realm.objects(Community.self)
self.collectionView.dataSource = self
self.collectionView.delegate = self
})
}
func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
do something
}
}
My Problem is now, I want the "Channel Cells" to fill with customized and different data, in the CollectionView. That means I need some sort of key to get the right data in the right cell. My approach would be to take the SectionHeader Title, but for some reasons I cant access it from the TableViewCellSmall. So I have all the data in all the Cells and cant sort them without my Key.
Thanks in Advance.

Answer 1

from what I understand you need to fill the collectionview of each cell with different contents and for this needs to identify the cell?
If so, I used the method below that helped me, you can try.
If in doubt let me know so I can help, I hope I have helped :)
//TableViewCell Add
var didCollectionViewCellSelect: ((Int) -> Void)?
override func setSelected(_ selected: Bool, animated: Bool)
{
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
//TabelView Add
class myClass: UITableViewController
{
var storedOffsets = [Int: CGFloat]()
override func viewDidLoad()
{
super.viewDidLoad()
}
override func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath)
{
guard let tableViewCell = cell as? myTableViewCell else { return }
let secao = indexPath.section*1000 //Section
let linha = indexPath.row //Row
let posicao = secao+linha
tableViewCell.setCollectionViewDataSourceDelegate(self, forRow: posicao)
tableViewCell.collectionViewOffset = storedOffsets[posicao] ?? 0
}
override func tableView(_ tableView: UITableView, didEndDisplaying cell: UITableViewCell, forRowAt indexPath: IndexPath)
{
guard let tableViewCell = cell as? myTableViewCell else { return }
let secao = indexPath.section*1000 //Section
let linha = indexPath.row //Row
let posicao = secao+linha
storedOffsets[posicao] = tableViewCell.collectionViewOffset
}
}
//CollectionView
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int
{
let posicao = collectionView.tag
let secao = Int(collectionView.tag/1000) //Section
let linha = posicao-(secao*1000) //Row
var qtd = 0
if secao == 0 && arrStation.count > 0
{
qtd = arrStation.count
}
return qtd
}
