Popover Controller doesn't show view correctly

Question

I have a ViewController that when the right barButton is pressed, a popover view shows. The popover view is a table view controller,

The problem is that when the popover shows, it just shows a view (not a table view).

But when the popover is dismissed, you can see that it flips to a tableview really quickly before it disappears.

Why would this be?

Update: Added popController.sourceView = sender; at the end here per @sticker:

- (IBAction)pressedButton:(id)sender {
    NSLog(@"Pressed Button");

    // grab the view controller we want to show
    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
    UIViewController *controller = [storyboard instantiateViewControllerWithIdentifier:@"Pop"];

    // present the controller
    // on iPad, this will be a Popover
    // on iPhone, this will be an action sheet
    controller.modalPresentationStyle = UIModalPresentationPopover;
    [self presentViewController:controller animated:YES completion:nil];

    // configure the Popover presentation controller
    UIPopoverPresentationController *popController = [controller popoverPresentationController];
    popController.permittedArrowDirections = UIPopoverArrowDirectionAny;
    popController.barButtonItem = self.barbutton;
    popController.delegate = self;

    // Added per @sticker
    popController.sourceView = sender;
}

Also made sure PopTableViewController had <UITableViewDelegate, UITableViewDataSource> for sure.

I'm still getting no tableview showing until the popover gets dismissed:

(below is what happens as soon as popover is dismissed and animating away)

I just try this one and it work fine Hope it help you

 self.tbVC.modalPresentationStyle = UIModalPresentationPopover;
    UIPopoverPresentationController *popOverVC =   [self.tbVC popoverPresentationController];
    popOverVC.barButtonItem = sender;
    popOverVC.permittedArrowDirections = UIPopoverArrowDirectionAny;


    [self presentViewController:_tbVC animated:YES completion:nil];
