func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = Collection_View.dequeueReusableCell(withReuseIdentifier: "list", for: indexPath) as! List_CollectionViewCell
cell.list_name.text = items[indexPath.row]
**cell.created_date.text = c_date[indexPath.row]**
return cell
}
为什么xcode在此行上生成此错误?
