Adding An UITableViewController on to a SubView

An UITableViewController pretty much takes up the entire view. I need a way to limit its height, width and add some shadows etc. For a clear explanation, I won't show the UITableViewController's contents.

Without the use of a storyboard, I subviewed the UITableViewController:

// In another UIViewController

let otherController = OtherController() // A subclass of UITableViewController
let otherControllerView = otherController.view

someView.addSubView(otherControllerView)

[...] // bunch of constraints

Notes:

In AppDelegate, if I set the rootController as OtherController(), everything works as it should. If I change it back to SomeView(), I see my modified tableView. If I should click it, it disappears.

This was the only thing that came close to my issue but sadly, I could not understand the answers provided as nothing made any sense to me.

I need to understand, why it disappears when touched etc.

view.bringSubviewToFront(...) proved futile. I'm gessing that a tableView should be rendered in its own controller and not in another view?

You must add the instance of UITableViewController's subclass as child view controller of the other view controller. You need to ensure few points in order to make it work. The points are as listed below:

  1. Create the instance of your TableViewController
  2. Add it as a child view controller of the other view controller
  3. Add its view as a subview of the desired view (you may do these steps in viewDidLaod since they need to be done only once)
  4. Keeping in mind the view cycle of a view controller. You must keep a weak reference of the child view controller aka TableViewController to adjust its view frame after the parent view controller has laid its subviews.

Code here:

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
    let vc = TableViewController()
    addChildViewController(vc)
    view.addSubview(vc.view)
    vc.didMove(toParentViewController: self)
    childVC = vc
}

override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()

    childVC?.view.frame = view.frame
}

So just to answer this question, indeed you got two options. One is the best way, as suggested by Rakesha. Just use UITableView. Add it as a subview. Done.

And in the future, if you really want any controller to be added onto any UIView, remember you need to add that controller as a child. For example, in your case:

The controller of the view that will hold your UITableViewController will add such UITableViewController as a child.

self.addChild(yourUITableViewController)
self.whatEverViewContainer.addSubview(yourUITableViewController.view) 
// Take note of the view of your tableViewController above^.
// Then setup the constraints of your yourUITableViewController.view below.

I hope this helps!
