Can a UIPopoverController be moved around the screen?

Is it possible to move the UIPopovercontroller around the screen once it has already been presented?
 I have a little idea in my application that can move a little, and I would like the UIPopoverController to move with it, without having to rethink the UIPopoverController every time it moves. Is it possible?

Like iOS 9, "UIPopoverController is deprecated. Travel companions are now implemented as UIViewController presentations. Use the modal presentation style of UIModalPresentationPopover and UIPopoverPresentationController."

, popover. sourceRect sourceView, API.

    DetailViewController *detailVC = self.detailViewController;
    detailVC.preferredContentSize = CGSizeMake(420, 92);
    detailVC.modalPresentationStyle = UIModalPresentationPopover;


    UIPopoverPresentationController *presController = detailVC.popoverPresentationController;
    if (presController) {
        presController.delegate = detailVC;
        presController.barButtonItem = self.detailButton;
        presController.sourceRect = self.view.frame;
        presController.sourceView = self.view;
        presController.permittedArrowDirections = UIPopoverArrowDirectionAny;
    }

    [self presentViewController: detailVC animated:YES completion:^{

    }];

, popover, popover .

DetailViewController *detailVC = self.detailViewController;
[self dismissViewControllerAnimated:NO completion:^{

    UIPopoverPresentationController *presController = detailVC.popoverPresentationController;
    if (presController) {
        presController.delegate = detailVC;
        presController.barButtonItem = self.detailButton;
        presController.sourceRect = self.view.frame; //Update frame
        presController.sourceView = self.view;
        presController.permittedArrowDirections = UIPopoverArrowDirectionAny;
    }

    [self presentViewController: detailVC animated:NO completion:^{

    }];
}];
