Adding button to Tableview cell - ios

Question

Okay, so I am trying to add a button to a table view cell. My table view cell has an image, label and a button. I set the button to be hidden in storyboard. Now I'm trying to show the button if the label text is truncated, I set the number of lines on my label to 3 in storyboard. It works but when I scroll up and down, somehow some cells with the label text not truncated shows a button. Why?
This is how my cell file looks atm.
class ItemCell: UITableViewCell {
#IBOutlet weak var itemImageView: UIImageView!
#IBOutlet weak var itemTitleLabel: UILabel!
#IBOutlet weak var itemDetailLabel: UILabel!
#IBOutlet weak var moreButton: UIButton!
var item: Item? {
didSet {
configureCell()
}
}
private func configureCell() {
guard let item = item else { return }
itemImageView.image = item.image
itemTitleLabel.text = item.name
itemDetailLabel.text = item.description
if itemDetailLabel.isTruncated {
moreButton.isHidden = false
} else {
moreButton.isHidden = true
}
}
extension UILabel {
var isTruncated: Bool {
guard let labelText = text else {
return false
}
let labelTextSize = (labelText as NSString).boundingRect(
with: CGSize(width: frame.size.width, height: .greatestFiniteMagnitude),
options: .usesLineFragmentOrigin,
attributes: [.font: font],
context: nil).size
return labelTextSize.height > bounds.size.height
}
}
This is how my cellForRowAt looks like.
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
guard let cell = tableView.dequeueReusableCell(withIdentifier: "ItemCell", for: indexPath) as? ItemCell else {
return UITableViewCell()
}
let item = categories[indexPath.section].items[indexPath.row]
cell.item = item
print("Name: \(item.name)\nSection: \(indexPath.section)\nRow: \(indexPath.row)\nisTruncated: \(cell.itemDetailLabel.isTruncated)\n")
return cell
}
