Set UITableView's height to the height of its content with Auto Layout

Question

I have a View which has two labels and a Table View inside it. I want label 1 to always stay above my Table View and label 2, to be below the Table View. The problem is that

Answer 1

The below code worked for me.

1. Create an outlet for tableViewHeight.

@IBOutlet weak var tableViewHeight: NSLayoutConstraint!
var tableViewHeight: CGFloat = 0  // Dynamically calcualted height of TableView.

2. For the dynamic height of the cell, I used the below code:

func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
    return tableView.estimatedRowHeight
}

3. For height of the TableView, with dynamic heights of the TableView Cells:

func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
    print(cell.frame.size.height, self.tableViewHeight)
    self.tableViewHeight += cell.frame.size.height
    tableViewBillsHeight.constant = self.tableViewHeight
}

Explanation:

After the TableView cell is created, we fetch the frame height of the cell that is about to Display and add the height of the cell to the main TableView.
