How to add a UIView above the current UITableViewController

Question

I have difficulty adding a subview (UIView) from within the viewDidLoad method of a UITableViewController

This works:

[self.view addSubview:self.prog

Solution for swift (equivalent to Daniel Saidi):

If your controller is a UITableViewController in a Storyboard or XIB and you wish to reassign self.view to a standard UIView while preserving your existing table view:

@IBOutlet var tableViewReference: UITableView!
var viewReference: UIView!

Then in your implementation file:

Add these instance variables to your table view controller file:

override var tableView: UITableView! {
    get { return tableViewReference }
    set { super.tableView = newValue }
}

override var view: UIView! {
    get { return viewReference }
    set { super.view = newValue }
}

override func viewDidLoad() {
    super.viewDidLoad()
    self.edgesForExtendedLayout = UIRectEdge.None
    self.extendedLayoutIncludesOpaqueBars = false
    self.automaticallyAdjustsScrollViewInsets = false

    //rewiring views due to add tableView as subview to superview
    viewReference = UIView.init(frame: tableViewReference.frame)
    viewReference.backgroundColor = tableViewReference.backgroundColor
    viewReference.autoresizingMask = tableViewReference.autoresizingMask
    viewReference.addSubview(tableViewReference)
}

In your Storyboard or XIB file: Connect the tableView in the UITableViewController to the tableViewReference variable.

Then you will be able to add child views as follows:

self.view.addSubView(someView)
