Custom cell with UITableView inside UICollectionViewCell

I have a custom UICollectionViewCell for a UICollectionView. I have marked this custom class as UITableViewDataSource and UITableViewDelegate in order to put UITableView in each cell of Collection view.

The table view is rendering properly in each cell of collection view but the issue is with the data in those table view header and cells.

Example: I have 10 questions with 5 to 6 options for each question. I have kept number of items in collection view as count of questionList which creates correct number of collection view cells

override func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int
return questionList.count



When i create each cell as below:

override func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell

let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "cell", for: indexPath) as! QuestionCell

return cell



The custom cell (QuestionCell) is rendering properly but all the custom collection view cells are displaying only the first question with it's options. Question here i have is that how can i link the indexPath.item of each collection view cell with the indexPath of TableView cell inside QuestionCell class.

fileprivate func setUpViews()
tableView.delegate = self
tableView.dataSource = self
tableView.register(QuestionHeader.self, forHeaderFooterViewReuseIdentifier: headerId)
tableView.register(OptionCell.self, forCellReuseIdentifier: cellId)


func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView?
let header = tableView.dequeueReusableHeaderFooterView(withIdentifier: headerId) as! QuestionHeader

header.nameLabel.text = questionList[section].questionText

return header


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


return questionList[section].options.count


func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
let cell = tableView.dequeueReusableCell(withIdentifier: cellId, for: indexPath) as! OptionCell

cell.nameLabel.text = questionList[indexPath.row].options[indexPath.row].optionText

return cell


func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat
return 50.0



Any idea to proceed on this will be highly appreciated.

i think questionList[section].options.count has to change.

you want a put question list in each collection view cell right?

than use collectionView's indexPath as index of questionList not tableView's section

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int
return questionList[section].options.count



Should only one question from the questionList be passed to your QuestionCell rather than the entire list?
In your QuestionCell, it should look like:

func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView?
let header = tableView.dequeueReusableHeaderFooterView(withIdentifier: headerId) as! QuestionHeader

header.nameLabel.text = question.questionText

return header


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


return question.options.count


func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
let cell = tableView.dequeueReusableCell(withIdentifier: cellId, for: indexPath) as! OptionCell

cell.nameLabel.text = question.options[indexPath.row].optionText

return cell



I was able to resolve the issue by defining an IndexPath variable in a separate Swift class and setting it's value inside CollectionView's cellForItem function. With this approach, I was able to refer indexPath of each CollectionView cell inside the corresponding TableViewCell.

override func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell

cellIndex = indexPath.item

print("Cell index: ",cellIndex)
if indexPath.item > 0
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "collectionCell", for: indexPath) as! PageCell
cell.tableView.reloadData()
return cell

else
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "collectionCell", for: indexPath) as! PageCell
cell.tableView.reloadData()
return cell
