Using swift5 i tried below code but unable to make it a adjustable height of cell. Any one can help me in that? 

    tableView.rowHeight = tableView.frame.height/8

    func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
        tableView.estimatedRowHeight = 100
        return UITableView.automaticDimension
    }

  • You are looking for [this](https://developer.apple.com/documentation/uikit/uitableviewdelegate/1614998-tableview) method, that's where you should return `tableHeight / 8` – Savca Marin Feb 25 '20 at 08:31
  • If you are looking for dynamic height of the tableview, you can assign `tableView.estimatedRowHeight = 100 // you cell's height` `tableView.rowHeight = UITableView.automaticDimension` and also you can take height constraint of tableview and write ` self.tblHConstraint.constant = self.tblOfferView.contentSize.height` in `willDisplay cell` method – Niraj Feb 25 '20 at 08:39

Auto height

You need to confirm to UITableViewDelegate and then call these two methods.

func tableView(UITableView, heightForRowAt: IndexPath) -> CGFloat {
    return UITableView.automaticDimension
}

 func tableView(_ tableView: UITableView,  estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
    return 100
}

Or

tableview.rowHeight = UITableView.automaticDimension
tableview.estimatedRowHeight = 100

But in both cases, it is required the views in cell have both bottom and top constraints. Read the accepted answer of this question for more info.

  • Thank you for ur answer.I've tried the answer but the cell height only changed by _return 100_...and I added the cell architect I think added the constraint already.where did I miss???is's too tricky...@mahan – tzxdtc10 Feb 25 '20 at 09:21
  • @tzxdtc10 I do not know if it is tricky for you. Do you need to have auto height or fixed height (table.frame.height/8) ? `print(table.frame.height)` in one of the above methods should you have fixed height. I think it is either `0` or `nill`. – mahan Feb 25 '20 at 09:41
  • @tzxdtc10 I updated the asnwere. There was a problem. Return `return UITableView.automaticDimension` in `heightForRowAt` method and `100` in `estimatedHeightForRowAt` – mahan Feb 25 '20 at 11:17
  • Thank you for ur answer but it did not work for me .Finally, I change the tableView to UIView. – tzxdtc10 Feb 27 '20 at 02:04
