Listing contents using UITableView - ios

Question

I am a newbie to iOS programming and I am simply trying to set up a TableView which would populate array contents.
I keep running into the following error.
uncaught exception 'NSInternalInconsistencyException', reason: '-[UITableViewController loadView] loaded the "BYZ-38-t0r-view-8bC-Xf-vdC" nib but didn't get a UITableView.'
I looked into a couple suggested solutions already but none of them work for my case.
Some suggested that I make my ViewController to be a subclass of UIViewController but I get the following error from doing so.
Another suggested I use UIViewController instead of UITableViewController in my custom class but I get the following error doing so.

Sorry, not enough reputation points to post extra link.
I do have a general idea as to why this is happening but if anyone would explain to me exactly why and how to solve it, I'll sincerely appreciate it.

Answer 1

Please check ViewController named "AddQuestionTableViewController" on Storyboard.
I think you named "AddQuestionTableViewController" to wrong ViewController (not UITableViewController)

Answer 2

Some common causes for this have to do with Storyboard connections and the Table View Controller file. First, click on the Table View itself in Storyboard and check the Outlets.
If they are disconnected, drag from the circles in delegate and data source to the little table view controller icon at the top of the view controller.
Also, make sure your class is hooked up correctly. Go the ID page in storyboard for your Table View Controller (NOT the Table itself) and check the class.

Answer 3

The error had told you the details: [UITableViewController loadView] loaded the "BYZ-38-t0r-view-8bC-Xf-vdC" nib but didn't get a UITableView.
You should check your custom UITableView.
Your problem maybe:
Your did't set custom UITableView Identity to "BYZ-38-t0r-view-8bC-Xf-vdC" in you xib file. If so, go to xxx.xib->show identity inspector->Identity set Restoration Id to "BYZ-38-t0r-view-8bC-Xf-vdC".
You've set a xib file's Identity to "BYZ-38-t0r-view-8bC-Xf-vdC", but it's not a UITableView, it's a UIView or something. If so, set the identity to a custom UITableView
