These are my delegate methods for tablerow

    func numberOfSectionsInTableView(tableView: UITableView) -> Int {
        return 1
    }

    func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 2
    }    

func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat
    {

        println(indexPath.row)

        return 300.0;
    }

The println in heightForRowAtIndexPath is acting wierd, this is my output:

Why is it called so many times? only 2 cells are being shown in my UI.

Do you call reloadData() somewhere? – Miknash Sep 07 '15 at 14:41

No, there is no call to deloadData anywhere – Lord Vermillion Sep 07 '15 at 14:42

It should not matter how often the data source (or delegate) methods are called. The table view calls them whenever it finds it necessary to do so. – Martin R Sep 07 '15 at 14:46
