Tableview accessories don't load correctly

favorite












I am trying to display a checkmark next to favourited reports in my project. I save the title into Core Data successfully and fetch them successfully too. I load them into an array called favourite. I then compare against the title loaded into the cell.



func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{
guard let cell = tableView.dequeueReusableCell(withIdentifier: "CellClass") as? CellClass else { return UITableViewCell()}

cell.titleLbl.text = objArray[indexPath.section].sectionObj?[indexPath.row].title ?? "no title"
cell.descLbl.text = objArray[indexPath.section].sectionObj?[indexPath.row].authors ?? "no authors"

if (self.favourite.count > 0)
{
for i in 0...self.favourite.count - 1
{
if (objArray[indexPath.section].sectionObj?[indexPath.row].title == favourite[i].title!)
{
cell.accessoryType = .checkmark
}
}
}
return cell
}


Currently, I only have one piece of data in Core Data so one checkmark should be shown but it seems there is a recursive pattern of every 10 cells in my table view.

          Cells get reused. Whenever you conditionally set a property of a cell, you need to reset that property in other cases.



          The simplest solution is to set the accessoryType to .none before the loop (and before the if).



          I also suggest optimizing the title a bit. You call objArray[indexPath.section].sectionObj?[indexPath.row].title many times in this code. Do it once.



          func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
          let cell = tableView.dequeueReusableCell(withIdentifier: "CellClass") as! CellClass

          let title = objArray[indexPath.section].sectionObj?[indexPath.row].title ?? "no title"
          cell.titleLbl.text = title
          cell.descLbl.text = objArray[indexPath.section].sectionObj?[indexPath.row].authors ?? "no authors"

          cell.accessoryType = .none

          for favorite in self.favourite {
          if title == favourite.title {
          cell.accessoryType = .checkmark
          break // no need to keep looking
          }
          }

          return cell
          }


          I've shown lots of other code cleanup as well.
