I have a UITableView with a custom cell. There is a Button, one label and one hidden label in the cell. I want the hidden label be visible after clicking the button. But when I am using self sizing cells I can't reload my tableView after setting the hidden label to visible.

The self sizing cells are working just fine with these two lines of code in the viewDidLoad() function.

```
self.tableView.estimatedRowHeight = 68.0
self.tableView.rowHeight = UITableViewAutomaticDimension

```

This is my ViewController class:

```
class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {

@IBOutlet weak var tableView: UITableView!
override func viewDidLoad() {
    super.viewDidLoad()

    //Self sizing cells
    self.tableView.estimatedRowHeight = 68.0
    self.tableView.rowHeight = UITableViewAutomaticDimension
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return 1
}

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    var cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! CustomCell
    cell.leftLabel.text = "Left Label"
    cell.centerLabel.text = "I am the center label and I need a little more words because I am supposed to be a wrap content. I hope this is enough"
    cell.button.tag = indexPath.row
    cell.button.addTarget(self, action: "buttonAction:", forControlEvents: UIControlEvents.TouchUpInside)
    return cell
}

func buttonAction(sender: AnyObject) {
    var button: UIButton = sender as! UIButton
    let indexPath: NSIndexPath = NSIndexPath(forRow: button.tag, inSection: 0)
    var cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! CustomCell
    cell.centerLabel.hidden = false
    self.tableView.reloadData()
}
}

```

As soon as I call 

```
self.tableView.estimatedRowHeight = 68.0

```

the reloadData call in the buttonAction function doesn't work anymore.

Can anybody help me out with this problem?
Thanks!
