I have a% simple%. It is loaded from a UITableView and added as a .nib , it appears, loads the data, displays the same all correctly, however from the moment I select a cell, the data simply disappears. >

I'm currently using Swift, but I already had this same problem with Objective-C, which was resolved without any code changes , but now is no longer being resolved.

The creation code of subview follows:

override func viewDidLoad() {
        super.viewDidLoad()
        self.tableView.registerClass(UITableViewCell.self, forCellReuseIdentifier: "Cell")

        listObjectsToList = ["String 1","String 2","String 3"]

    self.view.frame.size = CGSizeMake(300, 110)
    self.view.layer.cornerRadius = 5
    self.view.layer.masksToBounds = true

    self.tableView.scrollEnabled = false
}

override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
        return 1
    }

override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return listObjectsToList.count
}

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    var cell: UITableViewCell = self.tableView.dequeueReusableCellWithIdentifier("Cell") as UITableViewCell
    cell.textLabel.text = listObjectsToList.objectAtIndex(indexPath.row) as? String
    return cell
}

override func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
    return 40
}

override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    self.tableView.deselectRowAtIndexPath(indexPath, animated: true)
    let objectSelected: AnyObject = listObjectsToList.objectAtIndex(indexPath.row)
    object.type = objectSelected as String
    self.view.removeFromSuperview()
}

Addition code as UITableView :

var listTypeTableViewController = NSBundle.mainBundle().loadNibNamed("TableViewTypeScheduling", owner: self, options: nil)[0] as ListTypeTableViewController
listTypeTableViewController.view.frame = CGRectMake(10, 80, 300, 130)
self.view.addSubview(listTypeTableViewController.view)

Note that the subview method is not called

Ok, I've come to the understanding of what you intend to do, and with that, you can not simply "extract" UITableView from within your controller to put in another view .

You will also need to include UITableViewController as the "child" of the child that will receive it. I changed the way it is added, it looks like this:

var listTypeTableViewController = ListTypeTableViewController(nibName: "TableViewTypeScheduling", bundle: nil)        
listTypeTableViewController.view.frame = CGRectMake(10, 80, 300, 130)        
addChildViewController(listTypeTableViewController)
view.addSubview(listTypeTableViewController.view)

The big point is the addChildViewController method, which adds the controller before adding the view that is inside it.
