Ios 弹出窗口显示为全屏

我想在视图控制器内显示视图控制器。我正在使用弹出序列来完成这项工作。第二视图控制器设置如下所示，但无论如何它都会全屏显示

 func tappedView3() {
    // get a reference to the view controller for the popover
    let popController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "popoverId")

    // set the presentation style
    popController.modalPresentationStyle = UIModalPresentationStyle.popover

    // set up the popover presentation controller
    popController.popoverPresentationController?.permittedArrowDirections = UIPopoverArrowDirection.up
    popController.popoverPresentationController?.delegate = self
    popController.popoverPresentationController?.sourceView = m_tumgun // button
    popController.popoverPresentationController?.sourceRect = m_tumgun.bounds

    // present the popover
    self.present(popController, animated: true, completion: nil)
}

// UIPopoverPresentationControllerDelegate method
func adaptivePresentationStyleForPresentationController(controller: UIPresentationController) -> UIModalPresentationStyle {
    // Force popover style
    return UIModalPresentationStyle.none
}

对此，您应该使用容器视图

请在此处阅读更多信息：

您可以在其他控制器中使用它，方法如下

let lifeStyleTablePopup = TablePopupController(nibName: NibName.TablePopupController.rawValue, bundle: nil)
self.present(self.lifeStyleTablePopup, animated: true, completion: {
})

我希望这将有助于您了解containerview，但我的问题是，我正在通过按钮打开第二个视图，当打开新的container视图时，该按钮将消失。例如，当我搜索时，该按钮应该仍在视图中。@EmreÖnder，容器视图就是视图。可以将其添加为主视图控制器的子视图。

let lifeStyleTablePopup = TablePopupController(nibName: NibName.TablePopupController.rawValue, bundle: nil)
self.present(self.lifeStyleTablePopup, animated: true, completion: {
})
