How to set view outlet for a UITableViewController?

I created an empty xib, I dragged a UITableViewController, set Custom class to my class that extends from UITableViewController at both the UITableViewController and File's Owner.

When I run, it says:

'A view can only be associated with at most one view controller at a time! View ; layer = ; contentOffset: {0, 0}> is associated with . Clear this association before associating this view with .'

At connections inspector I see that the UITableViewController element has:

  • tableView - Table View
  • view - Table View (greyed)
  • dataSource - Table View
  • delegate - Table View

First Responder has nothing.

File's Owner has:

  • tableView is not attached to anything
  • view - Table View

If I remove the view connection at File's Owner, it claims that the view outlet is not set.

It is difficult to imagine what happens based on the information provided. However:
The error message says that you have a UIView, and you try at runtime to connect this UIView to two UIViewControllers, which is not possible.
If you just subclass a UITableViewController, without adding properties or implementing methods, then setup a UITableViewController in an empty storyboard, and set the class of this UITableViewController to your subclass, you have only a single UITableViewController, and you will not get this error.
So somewhere in your project you must instantiate a second UITableViewController programmatically, and set its UIView property (which is a UITableView) to the UIView of the other UITableViewController.
You should ensure that you have only a single UITableViewController, namely your custom subclass.

I guess the correct answer is DON'T drag UITableViewController to the interface builder. Have 2 IBOutlets connected, one for the view, one for the table. DO drag a UITableView instead.

Hope this helps other people.
