UITableViewCell with unwanted extra objects when scrolling down - ios

Question

I have a view controller, in the viewdidload method I call a function to make some calls to retrieve data online.
After I retrieve the data I append them into an array and reload the table view
at first, everything looks great however, when I scroll down I get to see what you see down below.
extension CastTableViewController : UITableViewDelegate, UITableViewDataSource {
func conigure_cast_table () {
castTable.translatesAutoresizingMaskIntoConstraints = false
castTable.delegate = self
castTable.dataSource = self
castTable.register(ActorCell.self, forCellReuseIdentifier: ActorCell.cellid)
view.addSubview(castTable)
castTable.frame = view.bounds
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return cast.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = castTable.dequeueReusableCell(withIdentifier: ActorCell.cellid, for: indexPath) as! ActorCell
let name = cast[indexPath.row].name
let character_name = cast[indexPath.row].character
let pic = cast[indexPath.row].picture_path
cell.configure(name: name, charName: character_name, pic_url: pic)
return cell
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 100
}
}

Answer 1

i fixed this by using prepareforreuse
// in the custom cell class
override func prepareForReuse() {
super.prepareForReuse()
for subview in stack.arrangedSubviews {
stack.removeArrangedSubview(subview)
}
actorPic.image = nil
realName.banner_title.text = nil
realName.info.text = nil
character.banner_title.text = nil
character.info.text = nil
}
