我有一个带有自定义表格视图单元的表格视图。
每个单元可能具有不同的高度。
总共有14行,但其他行是不可见的,当我向上和向下滚动时,这些行会消失。
请建议我哪里做错了。这已经困扰我两天了,我找不到任何解决方案。
请在下面找到我的表格视图代码。

return dpcell
default:
let cell = self.tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! UITableViewCell
cell.textLabel?.text = "default"
print("==========dummy cell============\(indexPath.row)")
return cell
}
这是在向下滚动并向上滚动后发生的。
