Indexing Multiple Custom TableViewCell Xibs into TableView - ios

Question

I am creating a TableView that starts with an image at the top, approximately 5 cells of parsed json, another image, approximately 3 more cells of parsed json, and another image.
I have 3 custom nibs that I am using. Each one is unique.
I get an "Index out of range" error on the line "let item = page?.collapsibles[indexForSecondSetTableViewCells]"
Here is my code:
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let currentIndex = indexPath.row - 1
let numberofCarousels = self.page?.carousels.count
let indexAfterCarousels = numberofCarousels ?? 00 + 1
let indexForSecondSetTableViewCells = indexAfterCarousels + 1
if indexPath.row == 0 {
let cell = tableView.dequeueReusableCell(withIdentifier: "pipesOne", for: indexPath) as! Pipes1TableViewCell
cell.pipesOne.image = UIImage(named: "WhatsNew1")
return cell
}
if indexPath.row == indexAfterCarousels {
let cell = tableView.dequeueReusableCell(withIdentifier: "pipesOne", for: indexPath) as! Pipes1TableViewCell
cell.pipesOne.image = UIImage(named: "WhatsNew2")
return cell
}
if indexPath.row == indexForSecondSetTableViewCells {
let cell = tableView.dequeueReusableCell(withIdentifier: "collapsibleCell", for: indexPath) as! CollapsiblesTableViewCell
let item = page?.collabsible[indexForSecondSetTableViewCells]
cell.collabsibleTitle.text = item?.title
cell.collabsibleDescription.text = item?.content
return cell
}
let cell = tableView.dequeueReusableCell(withIdentifier: "newsTableViewCell", for: indexPath) as! NewsTableViewCell
let item = page?.carousels[currentIndex]
cell.newsTitle.text = item?.title
cell.newsText.text = item?.caption
cell.newsImage.kf.setImage(with: page?.carousels[currentIndex].imageURL)
return cell
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return (page?.carousels.count ?? 0) + 1 + (page?.collapsibles.count ?? 0)
}
Update: I simplified the code to use the same json object twice and so that each item maps to exactly the cell that it should go to and I still get the "Fatal error: Index out of range" error at row 7 with let item = page?.collapsible[indexPath.row]
New code:
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if indexPath.row == 0 {
let cell = tableView.dequeueReusableCell(withIdentifier: "pipesOne", for: indexPath) as! Pipes1TableViewCell
cell.pipesOne.image = UIImage(named: "WhatsNew1")
return cell
}
if indexPath.row == 1 {
let cell = tableView.dequeueReusableCell(withIdentifier: "newsTableViewCell", for: indexPath) as! NewsTableViewCell
let item = page?.carousels[indexPath.row]
cell.newsTitle.text = item?.title
cell.newsText.text = item?.caption
cell.newsImage.kf.setImage(with: page?.carousels[indexPath.row].imageURL)
return cell
}
if indexPath.row == 6 {
let cell = tableView.dequeueReusableCell(withIdentifier: "pipesOne", for: indexPath) as! Pipes1TableViewCell
cell.pipesOne.image = UIImage(named: "WhatsNew2")
return cell
}
if indexPath.row == 7 {
let cell = tableView.dequeueReusableCell(withIdentifier: "collapsibleCell", for: indexPath) as! CollapsiblesTableViewCell
let item = page?.collapsibles[indexPath.row]
cell.collabsibleTitle.text = item?.title
cell.collabsibleDescription.text = item?.content
return cell
}
return UITableViewCell()
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 11
}

Answer 1

Try to print("\(indexPath)") in
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
print("\(indexPath)")
}
Then you will know how many rows it successfully shows before crash.
Then in cellForRowAt put conditional break point such it stops when indexPath is the one it crashed.
Now do po (page?.carousels.count ?? 0) + 1 + (page?.collapsibles.count ?? 0)
to see how many rows your tableview has. Most definitely indexForSecondSetTableViewCells is more than the number of rows
