Multiple CollectionView inside TableView Swift - swift

Question

I have a Tableview, I have a collectionView in it. There is imageView inside the CollectionView. As you can see in the photo at the moment, two TableViews are created separately. But the data in the CollectionViews inside this tableView is the same. Important: I have one collectionView. CollectionView is created according to the tableView Count. The collectionView's hps has the same data. I want to upload different data to CollectionViews, how can I do this? There is a well-known tableView for circumcision and weddings, but the CollectionView contents are the same. I have to do it differently.
For example, I want to add the data in davetiyefilee Array to 1.CollectionView. 2.I want to add the data from davetiyefilee2 Array to the CollectionView
enter image description here
enter image description here
UITableViewCell
class CategoryRow : UITableViewCell {
#IBOutlet weak var firstColView: UICollectionView!
var data = [String]()
var collectionData = [[String]]()
}
extension CategoryRow : UICollectionViewDataSource {
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return collectionData.count
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "cellDav1", for: indexPath) as! anaSayfaCell
let rowValue = collectionData[indexPath.row]
for i in 0..<rowValue.count {
let deneme = collectionData[firstColView.tag][indexPath.item]
let urlNew = URL(string: deneme)
cell.denemeImage.sd_setImage(with: urlNew)
}
return cell
}
func setData(data: [String])
{
self.data = data
self.firstColView.reloadData()
}
func setDataa(collectionData: [[String]])
{
self.collectionData = collectionData
self.firstColView.reloadData()
}
}
MainView
extension anaSayfaViewController : UITableViewDelegate { }
extension anaSayfaViewController : UITableViewDataSource {
func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
return kategoriIsımYeni[section]
}
func numberOfSections(in tableView: UITableView) -> Int {
return kategoriIsımYeni.count
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 1
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell") as! CategoryRow
cell.setData(data: davetiyefilee)
cell.setDataa(collectionData: collectionData)
return cell
}
}
class anaSayfaViewController: UIViewController, UISearchBarDelegate {
var collectionData = [[String]]()
var davetiyefilee = [String]()
var davetiyefilee2 = [String]()
#objc func davetiyeCEK1(){
if let baslik = try JSONSerialization.jsonObject(with: data, options: []) as? [[String: Any]] {
for review in baslik {
if let soru_baslik = review["davetiyefilee"] as? String {
let s = String(describing: soru_baslik)
self.davetiyefilee.append(s)
self.collectionData.append([s])
DispatchQueue.main.async { self.tableViewKategoriler.reloadData() } } } }
if let baslik = try JSONSerialization.jsonObject(with: data, options: []) as? [[String: Any]] {
for review in baslik {
if let soru_baslik = review["davetiyefilee"] as? String {
let s = String(describing: soru_baslik)
self.davetiyefile2.append(s)
self.collectionData.append([s])
DispatchQueue.main.async {
self.tableViewKategoriler.reloadData()
} } } }}

Swift has a handy property to its Views called tag. You can assign a unique tag to each of your CollectionViews and then add your data based on a condition like:
if collectionView.tag == 0 {
\\ your first collection view data assignment
} else if collectionView.tag == 1 {
\\ your second collection view data assignment
collectionView here refers to the parameter given by the collectionView functions above. You can assign tags using storyboard, but it is better to do that programmatically if you have many collectionViews.
