dynamic tableview inside custom tableviewcell - ios

Question

I'm trying to create a tableview with custom cells that each one holds a tableview.
I want to show the inner tableview just when it have some data (most of the time it's empty). I've managed to display the cells but can't display their tableview if it's populated with data.
The problem also is that the cell height needs to be dynamic according to the amount of data to display.
The cell code:
class feedViewCell: UITableViewCell , UITableViewDataSource , UITableViewDelegate {
#IBOutlet var feedCellImage: UIImageView!
#IBOutlet var feedCellUserName: UILabel!
#IBOutlet var feedCellDate: UILabel!
#IBOutlet var feedCellComments: UILabel!
#IBOutlet var cardView: UIView!
#IBOutlet var repliesTableView: UITableView!
var repliesArray:[Reply] = []
#IBAction func addComment(sender: AnyObject) {
}
override func awakeFromNib() {
super.awakeFromNib()
var nib = UINib(nibName: "feedComment", bundle: nil)
repliesTableView.registerNib(nib, forCellReuseIdentifier: "commentCell")
}
override func setSelected(selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
override func layoutSubviews() {
cardSetup()
}
func cardSetup() {
cardView.layer.masksToBounds = false
cardView.layer.cornerRadius = 5
cardView.layer.shadowOffset = CGSizeMake(-0.2, 0.2)
cardView.layer.shadowRadius = 1
cardView.layer.shadowOpacity = 0.2
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return repliesArray.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var cell = repliesTableView.dequeueReusableCellWithIdentifier("commentCell", forIndexPath: indexPath) as CommentFeedCell
cell.commentCellUserName.text = repliesArray[indexPath.row].userName
return cell
}
}
And the Main controller code:
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var comment = comments[indexPath.row]
let cell: feedViewCell = tableView.dequeueReusableCellWithIdentifier("feedCell", forIndexPath: indexPath) as feedViewCell
cell.feedCellUserName.text = comment.userName
cell.feedCellImage.backgroundColor = UIColor.redColor()
cell.feedCellComments.text = "\(comment.replies.count) COMMENTS"
cell.repliesArray = comment.replies
var dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "dd-MM-yyy"
cell.feedCellDate.text = dateFormatter.stringFromDate(NSDate())
if cell.repliesArray.count > 0 {
cell.repliesTableView.rowHeight = UITableViewAutomaticDimension
}
cell.repliesTableView.reloadData()
return cell
}
How to show the inner tableview only in cells which have comments (and hiding the tableview in cells with 0 comments)?

Call super in layoutSubviews and let us know what happens.
override func layoutSubviews() {
super.layoutSubviews()
cardSetup()
}
