var arrSelectedRows:[Int] = []
var arrSubCat:[String] = []
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return getSubCategory?.result?.sub_categories?.count ?? 0

var removeIndex: Int?
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "EditLangTableVIewCell", for: indexPath) as! EditLangTableVIewCell
let id = getSubCategory?.result?.sub_categories?[indexPath.row].id ?? 0
if arrSelectedRows.contains(id){
cell.langSelectButn.setImage(UIImage(systemName: "checkmark"), for: .normal)

CodePudding user response:
Modify the code of checkBoxSelection()
method like below
if self.arrSelectedRows.contains(sender.tag){
if let selectedIndex = self.arrSelectedRows.firstIndex(of: sender.tag) {
self.arrSelectedRows.remove(at: selectedIndex)
arrSubCat.remove(at: selectedIndex)
}
}
