How to save selected item in tableviewcell - ios

Question

I want to ask how can save selected all item in tableViewCell like this picture below. so later I can post it with with alamofire, I don't have any experience with posting data before. here is what have I done.
this is my button so I can later post in with alamofire, so far I want to test it.
#objc func handleSubmit() {
var data: [String] = []
for (index, value) in attendance.enumerated() {
print("index attendance: \(index), value attendance: \(value.status)")
let cell = tableView.cellForRow(at: IndexPath(item: index, section: 0)) as? GStudentAbsenceCell
UserServices.shared.postUserAttendances(status: cell?.status ?? "")
data.append(cell?.status ?? String(index))
}
print(data)
}
// In My UITableViewCell
var status: String?
statusLbl.didSelect { (selectedText , index ,id) in
if selectedText == "Sakit" || selectedText == "Izin" || selectedText == "Alpha" {
self.status = selectedText
self.statusLbl.backgroundColor = #colorLiteral(red: 0.8666666667, green: 0.4078431373, blue: 0.2705882353, alpha: 0.2)
self.statusLbl.textColor = #colorLiteral(red: 0.8666666667, green: 0.4078431373, blue: 0.2705882353, alpha: 1)
}
}

You cannot safely store your data models state in a table view cell, because upon scrolling the cell will likely to be reused for newly visible rows, hence it will store the state for a different row and therefore will lose the "old" state.
You need to store the state in your model; if it's not feasible to use your existing model, you might create a transient dictionary which maps the IndexPath to the state
What you could do is the following:
Extend your Cell with a custom callback handler, which is called when the status is changed.
When you set up your cell, hand in a closure that will deal with those status changes
In that closure, update the model
Some pseudo code might help you:
// in your custom cell
typealias Handler: (String) -> ()
class CustomTableViewCell : UITableViewCell {
var selectionHandler:Handler?
func didSelect(...) {
selectionHandler?(lblStatus.text)
}
}
// in your view controller
// in rowForCellatIndexPath:
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: IndexPath) -> UITableViewCell {
let cell = /* dequeue */ as! CustomTableViewCell
cell.selectionHandler = { statusText in
let row = indexPath.row
attendance[row].status = statusText /* get the status from the cell */
}
return cell
}
