TableView rows dissapear when tapped - swift

Question

I have a table view embedded in an iCarousel item and firstly I can't seem to set the view frame whether it's in viewDidLayoutSubviews() but also when I tap the Tableview all the cells disappear. I have created the Tableview in its own ViewController as each carousel item will need editing buttons for the Tableviews they contain. If I don't put the Tableview in its own view controller the cells remain but I get an index out of range when scrolling a lot of views and I can't add editing buttons. I've run out of ideas and would love some pointers or tips.
class BillSplitterTableView: UIViewController, UITableViewDataSource, UITableViewDelegate {
var splitter: BillSplitter?
var tableView: UITableView!
var viewFrame: CGRect?
init(frame: CGRect, splitter: BillSplitter) {
super.init(nibName: nil, bundle: nil)
self.splitter = splitter
self.viewFrame = frame
}
required init(coder aDecoder: NSCoder) {
fatalError("init(coder:)")
}
override func viewDidLoad() {
super.viewDidLoad()
let subView = UIView(frame: viewFrame!)
view.backgroundColor = .clear
tableView = UITableView(frame: view.frame)
tableView.delegate = self
tableView.dataSource = self
tableView.frame = subView.frame
tableView.separatorStyle = .none
tableView.estimatedRowHeight = 35
let tableViewBackground = UIImageView(image: UIImage(data: splitter?.image as! Data, scale:1.0))
tableViewBackground.contentMode = .scaleAspectFit
tableViewBackground.frame = tableView.frame
tableView.backgroundView = tableViewBackground
subView.addSubview(tableView)
view.addSubview(subView)
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return UITableViewAutomaticDimension
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if (splitter?.items?.count)! > 0 {
return (splitter!.items?.count)!
} else {
TableViewHelper.EmptyMessage("\(splitter?.name!) has no items to pay for.", tableView: tableView)
return 0
}
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
tableView.register(SplitterCarouselItemTableViewCell.classForCoder(), forCellReuseIdentifier: "splitterCarouselItemTableViewCell")
let cell: SplitterCarouselItemTableViewCell = tableView.dequeueReusableCell(withIdentifier: "splitterCarouselItemTableViewCell") as! SplitterCarouselItemTableViewCell
let item = (splitter?.items?.allObjects as! [Item])[indexPath.row]
let count = item.billSplitters?.count
cell.backgroundColor = UIColor(netHex: 0xe9edef).withAlphaComponent(0.5)
if count! > 1 {
cell.name!.text = "\(item.name!)\nsplit \(count!) ways"
cell.price!.text = "£\(Double(item.price)/Double(count!))"
} else {
cell.name!.text = item.name!
cell.price!.text = "£\(item.price)"
}
return cell
}
}
the carousel viewcontroller:
func numberOfItems(in carousel: iCarousel) -> Int {
return allBillSplitters.count
}
func carousel(_ carousel: iCarousel, viewForItemAt index: Int, reusing view: UIView?) -> UIView {
let splitter = allBillSplitters[index]
carouselIndex = index
let splitterView = SplitterCarouselItemView(frame: CGRect(x: 0, y: 0, width: width, height: height))
let viewWidth = Int(splitterView.frame.width)
let nameLabel = SplitterCarouselItemNameLabel(frame: CGRect(x: 0, y: 0, width: viewWidth, height: 30))
let emailLabel = SplitterCarouselItemEmailLabel(frame: CGRect(x: 0, y: 30, width: viewWidth, height: 20))
let addItemButton = SplitterCarouselItemButton(frame: CGRect(x: viewWidth - 45, y: 50, width: 35, height: 35), addsItem: true)
let deleteItemButton = SplitterCarouselItemButton(frame: CGRect(x: 15, y: 50, width: 35, height: 35), addsItem: false)
let itemHeight = Int(splitterView.frame.height)
let payTotalButton = SplitterCarouselItemPayButton(frame: CGRect(x: 0, y: itemHeight - 35, width: viewWidth + 1, height: 35))
let tableViewHeight = Int(height - 130)
let frame = CGRect(x: 0, y: 85, width: viewWidth, height: tableViewHeight)
let tableView = BillSplitterTableView(frame: frame, splitter: splitter)
splitterView.addSubview(nameLabel)
splitterView.addSubview(emailLabel)
splitterView.addSubview(addItemButton)
splitterView.addSubview(deleteItemButton)
splitterView.addSubview(tableView.view)
splitterView.addSubview(payTotalButton)
nameLabel.text = "\(allBillSplitters[index].name!)"
emailLabel.text = "\(allBillSplitters[index].email!)"
payTotalButton.setTitle("Pay £\(allBillSplitters[index].total)", for: .normal)
return splitterView
}
func carousel(_ carousel: iCarousel, valueFor option: iCarouselOption, withDefault value: CGFloat) -> CGFloat {
if allBillSplitters.count > 2 {
switch option {
case .spacing:
return value * 1.05
case .fadeMin:
return 0.0
case .fadeMinAlpha:
return 0.3
case .fadeMax:
return 0.0
default:
return value
}
}
return value
}
Thanks for any help in advance
