带视频播放功能的admob非页内广告iOS

如何解决带视频播放功能的admob非页内广告iOS

我正在使用包含vidoe的表格视图单元构建应用程序，我添加了插页式广告，但是当我单击该单元格并且必须再次单击该单元格才能播放视频时，它会显示。是否有办法使其在播放后自动播放广告加载

我的代码：

{
    import UIKit
    import Foundation
    import Firebase
    import FirebaseDatabase
    import AVKit
    import GoogleMobileAds

    class channelsViewController: UIViewController,UITableViewDelegate,UITableViewDataSource
    {

        var interstitial: GADInterstitial!

        var table = [Videos]()
        var ref: DatabaseReference!
        
        @IBOutlet var Tableview: UITableView!

        override func viewDidLoad() 
        {
            super.viewDidLoad()
            
            
            interstitial = GADInterstitial(adUnitID: "ca-app-pub-3940256099942544/4411468910")
            let request = GADRequest()
            interstitial.load(request)
            
            ref = Database.database().reference().child("videos")
            
            ref.observe(DataEventType.value,with: {(snapshot) in
                if ( snapshot.childrenCount > 0 ) 
                {
                    self.table.removeAll()
                    
                    for video in snapshot.children.allObjects as! [DataSnapshot] 
                    {
                        
                        let Object = video.value as? [String: AnyObject]
                        let Title = Object?["Title"]
                        let videolink = Object?["link"]
                        
                        
                        let video = Videos(Title: Title as! String,link: videolink as! String)
                        self.table.append(video)

                    }
                }
                
            })

            if interstitial.isReady { interstitial.present(fromrootViewController: self) }

            func createad() -> GADInterstitial
