通过设备旋转调整tableView的大小

Question

I am trying to make a tableView that fills my screen. And on launch, whether the table is horizontal or vertical, it always looks good:

But once you rotate the device, the tableView reveals the screen behind it:

I first tried using a recommendation from SO of this code snippet:

tableView.autoresizingMask = UIViewAutoresizingFlexibleWidth | 
                             UIViewAutoresizingFlexibleHeight

But I got the errors: use of unresolved identifier: UIViewAutoresizingFlexibleHeight use of unresolved identifier: UIViewAutoresizingFlexibleHeight

So I tried to reload the frame on rotation with:

didRotateFromInterfaceOrientation(fromInterfaceOrientation: UIInterfaceOrientation)

But that didn't seem to work either. Note that the view loads nicely in either landscape or portrait, but it goes awry once the view is flipped.

Here is the code I am currently rolling with in viewDidLoad:

  super.viewDidLoad()
    tableView = UITableView(frame: view.bounds, style: .plain)
    tableView.backgroundColor = UIColor.blue

    let cellNib = UINib(nibName: "PostTableViewCell", bundle: nil)
    tableView.register(cellNib, forCellReuseIdentifier: "postCell")
    view.addSubview(tableView)
    tableView.register(LoadingCell.self, forCellReuseIdentifier: "loadingCell")
    var layoutGuide:UILayoutGuide!

    layoutGuide = view.safeAreaLayoutGuide

    tableView.leadingAnchor.constraint(equalTo: layoutGuide.leadingAnchor).isActive = true
    tableView.topAnchor.constraint(equalTo: layoutGuide.topAnchor).isActive = true
    tableView.bottomAnchor.constraint(equalTo: layoutGuide.bottomAnchor).isActive = true
    tableView.trailingAnchor.constraint(equalTo: layoutGuide.leadingAnchor).isActive = true
    tableView.estimatedRowHeight = UITableViewAutomaticDimension
    tableView.frame = self.view.bounds
    tableView.delegate = self
    tableView.dataSource = self
    tableView.tableFooterView = UIView()
    tableView.reloadData()

Here's a pic of my story board for reference:

Thanks for the help.

Answer 1

You only need

tableView.translatesAutoresizingMaskIntoConstraints  = false
NSLayoutConstraint.activate([
  tableView.leadingAnchor.constraint(equalTo: layoutGuide.leadingAnchor),
  tableView.topAnchor.constraint(equalTo: layoutGuide.topAnchor),
  tableView.bottomAnchor.constraint(equalTo: layoutGuide.bottomAnchor),
  tableView.trailingAnchor.constraint(equalTo: layoutGuide.trailingAnchor) 
])

And comment

tableView.frame = self.view.bounds
