IndexPath for variable row - arrays

Question

I am using a UITableView with prototype cells. The main TableView is DiveDetails2VC and the prototype cell is based on DiveItemViewController via segue.
I need to save to parse the results, and have been able to save only row 0 to parse. I do not know how to set this up so that any row selected in the tableview is sent to parse. I am aware this is caused by the line in saveEntry:
let indexPath = NSIndexPath(forRow: 0, inSection: 0)
but I do not know how to set the forRow statement to allow any row within the displayed array. There is only one section.
DiveItemViewController
class DiveItemViewController: UITableViewController, ItemDataProtocol
{
private let NumberOfSections: Int = 1
// MARK: - Public Properties
//
// This property is an object that conforms to the ItemDataSelectedProtocol. We use it to call the
// selectedItem method.
//
var itemDataSelectedDelegate: AnyObject?
private var itemData: Array<String> = Array<String>()
override func viewDidLoad()
{
super.viewDidLoad()
// Adds "+" to dive item selection so divers can add another item to the selected list
navigationItem.rightBarButtonItem = UIBarButtonItem(barButtonSystemItem: .Add, target: self, action: #selector(DiveItemViewController.AddItemButton(_:)))
}
override func didReceiveMemoryWarning()
{
super.didReceiveMemoryWarning()
}

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
{
let cell: UITableViewCell! = tableView.dequeueReusableCellWithIdentifier(Resource.DiveItemCell)
if self.itemData.isEmpty == false
{
cell.textLabel?.text = itemData[indexPath.row]
}
parseItem = cell.textLabel!.text!
return cell
}
override func numberOfSectionsInTableView(tableView: UITableView) -> Int
{
return self.NumberOfSections
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int

if self.itemDataSelectedDelegate?.respondsToSelector(#selector(DiveDetails2VC.itemDataSelectedItem(_:))) != nil
{
(self.itemDataSelectedDelegate as! ItemDataSelectedProtocol).itemDataSelectedItem(indexPath.row)
}
tableView.deselectRowAtIndexPath(indexPath, animated: true)
}
override func tableView(tableView: UITableView, willDeselectRowAtIndexPath indexPath: NSIndexPath) -> NSIndexPath?

Answer 1

Declare a var in your viewController:
var selectedIndexPath: NSIndexPath?
And then in your didSelectRowAtIndexPath, set this var with the selected indexPath like:
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath)
{
if let _ = self.selectedIndexPath {
selectedIndexPath = indexPath
}else{
selectedIndexPath = NSIndexPath(forRow: indexPath.row, inSection: indexPath.section)
}
tableView.cellForRowAtIndexPath(indexPath)?.accessoryType = UITableViewCellAccessoryType.Checkmark
if self.itemDataSelectedDelegate?.respondsToSelector(#selector(DiveDetails2VC.itemDataSelectedItem(_:))) != nil
{
(self.itemDataSelectedDelegate as! ItemDataSelectedProtocol).itemDataSelectedItem(indexPath.row)
}
tableView.deselectRowAtIndexPath(indexPath, animated: true)
}
And then use this selectedIndexPath like this in your saveEntry method:
#IBAction func saveEntry (sender: AnyObject) {
if let indexPath = selectedIndexPath {
let cell = tableView.cellForRowAtIndexPath(indexPath)
...
}
}
EDIT: Added ")" behind "inSection: indexPath.section)"
