Fixe size subview in UiTableview swift 2 - uitableview

Question

I created a Uitableview in a ViewController and I want to set dynamically the size of each cell containing a subview. I try a lot of technics, the only one is using this function :
func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
return 150.0
}
but the value is fixe so a scroll bar appear in my tableview cell and I don't want that, I want to see all the subviews without a scroll bar, here is my code for the ViewController containing the tableview :
import UIKit
class ViewController: UIViewController,UITableViewDataSource,UITableViewDelegate {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 3;
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 1;
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var cell:CustomCell? = tableView.dequeueReusableCellWithIdentifier("Cell") as? CustomCell
if(cell == nil)
{
cell = CustomCell(style: UITableViewCellStyle.Default, reuseIdentifier: "Cell")
}
cell?.dataArr = ["Test 1","Test 2","Test 3","Test 4","Test 5"]
return cell!
}
func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
return 150.0
}
}
and here is the custom cell :
import UIKit
class CustomCell: UITableViewCell,UITableViewDataSource,UITableViewDelegate {
var dataArr:[String] = []
var subMenuTable:UITableView?
override init(style: UITableViewCellStyle, reuseIdentifier: String?) {
super.init(style: style , reuseIdentifier: reuseIdentifier)
setUpTable()
}
required init(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
setUpTable()
}
func setUpTable()
{
subMenuTable = UITableView()
subMenuTable?.delegate = self
subMenuTable?.dataSource = self
self.addSubview(subMenuTable!)
}
override func layoutSubviews() {
super.layoutSubviews()
subMenuTable?.frame = CGRectMake(0.2, 0.3, self.bounds.size.width-5, self.bounds.size.height-5)
}
override func setSelected(selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return dataArr.count
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var cell: UITableViewCell? = tableView.dequeueReusableCellWithIdentifier("cellID")
if(cell == nil){
cell = UITableViewCell(style: UITableViewCellStyle.Default, reuseIdentifier: "cellID")
}
tableView.rowHeight = UITableViewAutomaticDimension
tableView.estimatedRowHeight = 160.0
cell?.textLabel?.text = dataArr[indexPath.row]
return cell!
}
}
How can I fixed that ?

Try
func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
return tableView.cellForRowAtIndexPath(indexPath)?.contentView.frame.size.height
}
