iOS: Dynamically set UITableView height in Swift

Question

Our UITableView exists on a ViewController (and not a TableViewController). We populate it at run time with two rows. When we set a height constraint the table appears fin

Answer 1

You can change tableView frame in multiple ways, with animations etc.

tableView.frame = CGRect(x: leftTableBorder, y: topTableBorder, width: tableWidth, height: tableHeight)

Or you can change tableView related constraints and then update constraints with layoutIfNeeded, also animated if you wish.

For example if you have a height constraint property:

tableViewHeightConstraint.constant = desiredHeight

layoutIfNeeded()

In any case, constraints are needed, so autolayout knows how to render the table.
