Easiest usage of expandable & collapsible cell for iOS, written in Swift 4.2 You can customize expandable UITableViewCell whatever you like. YNExpandableCell is made because insertRows and deleteRows is hard to use. You can just inheirt YNTableViewDelegate and add one more method func tableView(_ tableView: YNTableView, expandCellAt indexPath) -> UITableViewCell?

Use one of required method

Set expandable cell in YNTableViewDelegate method (Required)

let ynSliderCell = tableView.dequeueReusableCell(withIdentifier: YNSliderCell.ID) as! YNSliderCell

if indexPath.section == 0 && indexPath.row == 1 {

return ynSliderCell

}

return nil

}

Set expandable cell with height in YNTableViewDelegate method using YNTableViewCell object (Required)

print(“Selected Section: \(indexPath.section) Row: \(indexPath.row) isExpandableCell: \(isExpandableCell) isExpandedCell: \(isExpandedCell)”)

}

Get didDeselectRowAt in YNTableViewDelegate method (Optional)

Set basic UITableViewDataSource, UITableViewDelegate and Done!

Customize

Expand & Collapse All if you want
