How to get the size of a UITableView's content view?

Question

I would like to get the size of a UITableView\'s content view when the table is populated. Any suggestions on how to do this?

Answer 1

For table views whose heights are dynamically sized by their cells' contents--

My tableView is contained in a UIView, whose updateConstraints() function looks like this:

override func updateConstraints() {
    self.tableView.layoutIfNeeded()
    self.tableViewHeight.constant = min(300, self.tableView.contentSize.height)
    super.updateConstraints()
}

tableViewHeight is an IBOutlet to the XIB-assigned height of the table view. I get whichever is smaller--300 points, or the height of the table view's content size.
