在presentedViewController?.dismiss之后快速调用presentedViewController？.dismiss

Question

我创建了一个方法来解除呈现的视图控制器，呈现的视图控制器确实被解除，但是没有被调用，我如何让它在解除呈现的视图控制器之后调用？

func dismissPresentedViewController() {
        self.presentedViewController?.dismiss(animated: true, completion: nil)
        popoverPresentationController?.delegate?.popoverPresentationControllerDidDismissPopover?(popoverPresentationController!)

    }

func popoverPresentationControllerDidDismissPopover(_ popoverPresentationController: UIPopoverPresentationController) {
        print("Here")
    }

未调用，是的，我有UIPopoverPresentationControllerDelegate

let popupController = storyboard?.instantiateViewController(withIdentifier: "CommentsView") as! CommentsController

popupController.modalPresentationStyle = .popover
popupController.preferredContentSize = CGSize(width: 400, height: 400)
if let popoverController = popupController.popoverPresentationController {
    popoverController.sourceView = (cell)
    popoverController.sourceRect = (cell?.bounds)!
    popoverController.permittedArrowDirections = .up
    popoverController.delegate = self
}


present(popupController, animated: true, completion: nil)

来自Apple's documentation…

popoverPresentationControllerDidDismissPopover(_:)

popover表示控制器在关闭popover之后调用此方法，以让您知道它不再显示在屏幕上。表示控制器仅在响应用户操作时调用此方法。如果您关闭popover programmatically.，则不会调用此方法
