how to hide empty rows in a UITableView and change the height of the Uitableview based on non-empty rows

Question

I have couple of problems with my UITableView.

1. When I add a UITableview on my page, by default it brings up some fixed number of rows,

Answer 1

For Swift:

override func viewWillAppear(animated: Bool) {
    self.tableView.tableFooterView = UIView(frame: CGRect.zeroRect)

// OR 

    self.tableView.tableFooterView = UIView()
}

For C#: (Please don't forget to add using CoreGraphics; )

public override void ViewWillAppear(bool animated)
{
    base.ViewWillAppear(animated);
    this.sampleTableview.TableFooterView = new UIView(frame: CGRect.Empty);
}
