我怎样才能用一个按钮做一个弹出视图，然后显示一个 tableView（以弹出格式）？

Question

我想在 UIViewController 上创建一个按钮，按下时以弹出窗口格式显示 UITableView。当我尝试时，我必须看到弹出窗口格式的表格视图，但我可以在上面显示我的内容。任何人都知道如何正确地使用 tableView 做一个弹出窗口？或者有人有这种情况的例子吗？（该按钮不是 UIBarButton，它是一个普通的 UIButton）。我试过这个：

import UIKit

class StadisticViewController: UIViewController, UIPopoverPresentationControllerDelegate {

var team: [Players] = []

override func viewDidLoad() {
    super.viewDidLoad()


}


@IBAction func showPopoverTapped(_ sender: UIButton) {
    self.performSegue(withIdentifier: "popSegue", sender: self)
}

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    if segue.identifier == "popSegue" {
        let controller = segue.destination as! PopViewController
        controller.popTeam = self.team
        controller.popoverPresentationController!.delegate = self
        controller.preferredContentSize = CGSize(width: self.view.frame.width, height: self.view.frame.height - 65.0)

    }
}


func adaptivePresentationStyle(for controller: UIPresentationController) -> UIModalPresentationStyle {
    return .none
}

}

从您的视图控制器创建一个弹出窗口通过拖动加号图标在该弹出窗口上添加锚点

class ViewController : UIViewController , UIPopoverPresentationControllerDelegate {


   @IBAction func showPopoverTapped(_ sender : UIButton) {
      self.performSegue("identifier" , sender : self)
    }




 override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    if segue.identifier == "identifier" {
        if let controller = segue.destination as? YourViewControllerClass {
            controller.popoverPresentationController!.delegate = self
            controller.delegate = self
            controller.preferredContentSize = CGSize(width: self.view.frame.width, height: self.view.frame.height - 65.0)
        }


    }
}

  func adaptivePresentationStyle(for controller: UIPresentationController) -> UIModalPresentationStyle {
    return .none
}

如果您想以编程方式进行

     else if senderTag == 2  {



    let sliderViewController =  storyboard?.instantiateViewController(withIdentifier: "BGPopover") as! AllDesignsViewController
   sliderViewController.modalPresentationStyle = .popover
   sliderViewController.preferredContentSize = CGSize(width: self.view.frame.width, height: 220)

    let popoverMenuViewController = sliderViewController.popoverPresentationController
    popoverMenuViewController?.permittedArrowDirections = .up
    popoverMenuViewController?.delegate = self
    // You Still Need Anchor point for popover i used bar  button as popover anchor. you can use any other UI Element
    // popoverMenuViewController?.sourceView = yourAnchorView
    // popoverMenuViewController?.sourceRect = yourAnchorView.bounds
    popoverMenuViewController?.barButtonItem = sideBarButton

    present(sliderViewController, animated: true, completion: nil)
}
