Swift 3 Table View - Remove Stack View from some cells

Question

I've got table view cells which contain, amongst other things, a stack view. The stack view should only be in a cell, if some requirements are true. If not, then the height of the cell should be reduced. When I use .isHidden, the height stays the same. But I want the stack view to be removed from that cell.

Here's my code:

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

    let cell = tableView.dequeueReusableCell(withIdentifier: "RumCell", for: indexPath) as! RumCell

    let currentRum: Rum
    currentRum = rumList[indexPath.row]

    cell.rum = currentRum

    if (cell.rum?.clubRatingJuicy == 0) && (cell.rum?.clubRatingGasy == 0) && (cell.rum?.clubRatingSpicy == 0) && (cell.rum?.clubRatingSweet == 0) {
        cell.frame.size.height -= 76
    }

    return cell
}

As you can see, I tried to reduce the cell height, but this doesn't work. I also tried this, which doesn't work:

    if (cell.rum?.clubRatingJuicy == 0) && (cell.rum?.clubRatingGasy == 0) && (cell.rum?.clubRatingSpicy == 0) && (cell.rum?.clubRatingSweet == 0) {
        cell.tastStack.removeFromSuperview()
    }

Can anyone please tell me how to do this?

Answer 1

you should use different cell prototypes RumCell (without stackview) and RumCellDetailed (with stackview) which both conform to a protocol RumCellProtocol (where you can set the rum var)

protocol RumCellProtocol {
    func config(rum: Rum)
}

and this code:

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

    var cellIdentifier = "RumCellDetailed"

    if (cell.rum?.clubRatingJuicy == 0) && (cell.rum?.clubRatingGasy == 0) && (cell.rum?.clubRatingSpicy == 0) && (cell.rum?.clubRatingSweet == 0) {
        cellIdentifier = "RumCell"
    }


    let cell = tableView.dequeueReusableCell(withIdentifier: cellIdentifier, for: indexPath) as! RumCellProtocol

    let currentRum: Rum
    currentRum = rumList[indexPath.row]

    cell.config(rum: currentRum)

    return cell
}
