Dynamic Height Issue for UITableView Cells (Swift)

Question

Dynamic text of variable length are being injected into tableview cell labels. In order for the tableview cells\' heights to be dynamically sized, I have implemented in

Answer 1

Unfortunately, I am not sure what I was missing. The above methods don't work for me to get the xib cell's height or let the layoutifneeded()or UITableView.automaticDimension to do the height calculation. I've been searching and trying for 3 to 4 nights but could not find an answer. Some answers here or on another post did give me hints for the workaround though. It's a stupid method but it works. Just add all your cells into an Array. And then set the outlet of each of your height constraint in the xib storyboard. Finally, add them up in the heightForRowAt method. It's just straight forward if you are not familiar with the those APIs.

Swift 4.2

CustomCell.Swift

@IBOutlet weak var textViewOneHeight: NSLayoutConstraint!
@IBOutlet weak var textViewTwoHeight: NSLayoutConstraint!
@IBOutlet weak var textViewThreeHeight: NSLayoutConstraint!

@IBOutlet weak var textViewFourHeight: NSLayoutConstraint!
@IBOutlet weak var textViewFiveHeight: NSLayoutConstraint!

MyTableViewVC.Swift

.
.
var myCustomCells:[CustomCell] = []
.
.
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = Bundle.main.loadNibNamed("CustomCell", owner: self, options: nil)?.first as! CustomCell

.
.
myCustomCells.append(cell)
return cell

}


override func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {

   let totalHeight = myCustomCells[indexPath.row].textViewOneHeight.constant + myCustomCells[indexPath.row].textViewTwoHeight.constant +  myCustomCells[indexPath.row].textViewThreeHeight.constant + myCustomCells[indexPath.row].textViewFourHeight.constant + myCustomCells[indexPath.row].textViewFiveHeight.constant

  return totalHeight + 40 //some magic number
