在其他場景中顯示插頁式廣告 - Admob，SpriteKit，Swift

Question

如何從admob每隔x次顯示一次插頁式廣告，用戶已死亡或每x次用戶執行類似按下按鈕？這就是我如何在我的GameScene上展示插頁式廣告，並通過簡單的if語句展示有限的廣告展示。

Answer 1

這隻有在您擁有GoogleMobileAds.sdk並將googlemobileads模塊導入GameViewController，GameScene或GameOverScene時纔有效。

我將向您展示跨場廣告實施並通過程序限制廣告展示次數。

首先，在你GameViewController：

import GoogleMobileAds 


class GameViewController: UIViewController, GADInterstitialDelegate { 



var myAd = GADInterstitial() 


override func viewDidLoad() { 
    super.viewDidLoad() 


    NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(GameViewController.loadAndShow), name: "loadAndShow", object: nil) 

} 

你GameViewController底部創建兩個功能：

func loadAndShow() { 



    myAd = GADInterstitial() 
    let request = GADRequest() 
    myAd.setAdUnitID("ca-app-pub-3940256099942544/4411468910") 
    myAd.delegate = self 
    myAd.loadRequest(request) 



} 

func interstitialDidReceiveAd(ad: GADInterstitial!) { 

    if (self.myAd.isReady) { 

     myAd.presentFromRootViewController(self) 



    } 



} 

您與GameViewController完成。現在前往GameOverScene或GameScene，無論您需要什麼。

創建一個全局int變量：

var playCount = Int() 

在你DidMoveToView說：

playCount = 1 

這部分是有點混亂，有點，不是真的。轉到觸摸開始，並找到將按鈕添加到按鈕的位置。例如，一個resetGame按鈕重置場景。添加這裏，並增加playButton Int像這樣：

override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) { 

    for touch in touches{ 



     let location = touch.locationInNode(self) 
     if resetGame.containsPoint(location) { 
      restartScene() 

      playCount += 1 


     } 

最後一步。這兩個功能添加到您希望在展示插頁式廣告場景的底部：

func displayAd() { 



NSNotificationCenter.defaultCenter().postNotificationName("loadAndShow", object: nil) 


} 

func checkAd() { 


    if playCount % 4 == 0 { 

     displayAd() 

    } 

} 

} 

現在，用戶按下復位按鈕，遊戲或死亡每第四次，插頁式廣告應該顯示。我希望這有幫助。

編輯：我忘了告訴你調用checkAd（）函數。在玩家死亡的任何地方調用此函數。所以如果你有一個名爲death或者gameover的Bool變量在同一個地方調用它。例如..

if died == true { 
    checkAd() 
}

import UIKit 

import SpriteKit 

import GoogleMobileAds 

var playCount = Int() 

class GameViewController: UIViewController, GADBannerViewDelegate { 
@IBOutlet var banner: GADBannerView! 

var myAd = GADInterstitial() 

override func viewDidLoad() { 
    super.viewDidLoad() 

NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(GameViewController.loadAndShow), name: "loadAndShow", object: nil) 

    let scene = MainScene(size: CGSize(width: 1536, height: 2048)) 


       // Configure the view. 
     let skView = self.view as! SKView 
     skView.showsFPS = false 
     skView.showsNodeCount = false 

     /* Sprite Kit applies additional optimizations to improve rendering performance */ 
     skView.ignoresSiblingOrder = true 

     /* Set the scale mode to scale to fit the window */ 
     scene.scaleMode = .AspectFill 

     skView.presentScene(scene) 

    banner.hidden = true 

    banner.delegate = self 

    banner.adUnitID = "ca-app-pub-8889875503423788/7902691359" 
    banner.rootViewController = self 
    banner.loadRequest(GADRequest()) 

} 

func loadAndShow() { 



    myAd = GADInterstitial() 
    let request = GADRequest() 
    myAd.setAdUnitID("ca-app-pub-8889875503423788/7902691359") 
    myAd.delegate = self 
    myAd.loadRequest(request) 



} 

func interstitialDidReceiveAd(ad: GADInterstitial!) { 

    if (self.myAd.isReady) { 

     myAd.presentFromRootViewController(self) 



    } 



} 

func adViewDidReceiveAd(bannerView: GADBannerView!) { 
    banner.hidden = false 
} 

func adView(bannerView: GADBannerView!, didFailToReceiveAdWithError error: GADRequestError!) { 
    banner.hidden = true 
}
