【问题描述】：

我使用 Swift 和 SpriteKit 制作了简单的游戏。一切似乎都正常，但我的 iAd 设置有问题。我只想在特定场景（主菜单和游戏结束）中显示广告横幅，而不是在游戏过程中。 我的 iAd 设置有效，但前提是它始终显示。 我最后一次尝试修复它是使用 NSNotificationCenter 方法。我已经这样做了，因为我在此处的其他问题/答案中看到了它，但应用程序在启动后立即崩溃。 希望有人可以帮助我。如果您需要更多我的代码，请告诉我。 提前致谢。

GameViewController.swift

class GameViewController: UIViewController, ADBannerViewDelegate 

var adBannerView = ADBannerView(frame: CGRect.zeroRect)

override func viewDidLoad() 
    super.viewDidLoad()

    NSNotificationCenter.defaultCenter().addObserver(self, selector: "handleNotification", name: "hideAd", object: nil)
    NSNotificationCenter.defaultCenter().addObserver(self, selector: "handleNotification", name: "showAd", object: nil)

    self.adBannerView.delegate = self
    self.adBannerView.hidden = true
    adBannerView.center = CGPoint(x: adBannerView.center.x, y: view.bounds.size.height - adBannerView.frame.size.height / 2)
    view.addSubview(adBannerView)

    if let scene = GameScene.unarchiveFromFile("GameScene") as? GameScene 
        // Configure the view.
        let skView = self.view as SKView

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

        var scene: SKScene = MainMenu(size: skView.bounds.size)
        scene.scaleMode = SKSceneScaleMode.AspectFill
        skView.presentScene(scene)
    


func handleNotification(notification: NSNotification)
    if notification.name == "hideAd"
        adBannerView.hidden = true
    else if notification.name == "showAd"
        adBannerView.hidden = false
    


//iAD Setup
func bannerViewWillLoadAd(banner: ADBannerView!) 
    println("Ad loads")


func bannerViewDidLoadAd(banner: ADBannerView!)
    println("Ad loaded")
    self.adBannerView.hidden = false


func bannerViewActionDidFinish(banner: ADBannerView!) 
    println("resume scene")
    let skView = self.view as SKView
    skView.paused = false


func bannerViewActionShouldBegin(banner: ADBannerView!, willLeaveApplication willLeave: Bool) -> Bool 
    println("pause scene")
    let skView = self.view as SKView
    skView.paused = true
    return true


func bannerView(banner: ADBannerView!, didFailToReceiveAdWithError error: NSError!) 
    println("Failed to load ad")
    self.adBannerView.hidden = true
   more code.... 

MainMenu.swift

class MainMenu: SKScene

required init(coder aDecoder: NSCoder) 
    fatalError("init(coder:) has not been implemented")


override init(size:CGSize)
    super.init(size: size)

    NSNotificationCenter.defaultCenter().postNotificationName("showAd", object: nil)
more code...

【参考方案1】：

这对我有用

在我的视图控制器中，我有以下代码：

// 横幅广告

var SH = UIScreen.mainScreen().bounds.height
let transition = SKTransition.fadeWithDuration(1) 
var UIiAd: ADBannerView = ADBannerView()

override func viewWillAppear(animated: Bool) 
    var BV = UIiAd.bounds.height
    UIiAd.delegate = self
    UIiAd.frame = CGRectMake(0, SH + BV, 0, 0)
    self.view.addSubview(UIiAd)


override func viewWillDisappear(animated: Bool) 
    UIiAd.delegate = nil
    UIiAd.removeFromSuperview()


func bannerViewDidLoadAd(banner: ADBannerView!) 
    var BV = UIiAd.bounds.height
    UIView.beginAnimations(nil, context: nil)
    UIView.setAnimationDuration(1) // Time it takes the animation to complete
    UIiAd.alpha = 1 // Fade in the animation
    UIView.commitAnimations()


func bannerView(banner: ADBannerView!, didFailToReceiveAdWithError error: NSError!) 
    UIView.beginAnimations(nil, context: nil)
    UIView.setAnimationDuration(1)
    UIiAd.alpha = 0
    UIView.commitAnimations()


func showBannerAd() 
    UIiAd.hidden = false
    var BV = UIiAd.bounds.height

    UIView.beginAnimations(nil, context: nil)
    UIView.setAnimationDuration(1) // Time it takes the animation to complete
    UIiAd.frame = CGRectMake(0, SH - BV, 0, 0) // End position of the animation
    UIView.commitAnimations()


func hideBannerAd() 
    UIiAd.hidden = true
    var BV = UIiAd.bounds.height

    UIView.beginAnimations(nil, context: nil)
    UIView.setAnimationDuration(1) // Time it takes the animation to complete
    UIiAd.frame = CGRectMake(0, SH + BV, 0, 0) // End position of the animation
    UIView.commitAnimations()


override func viewDidLoad() 
    super.viewDidLoad()
    self.UIiAd.hidden = true
    self.UIiAd.alpha = 0

    NSNotificationCenter.defaultCenter().addObserver(self, selector: "hideBannerAd", name: "hideadsID", object: nil)
    NSNotificationCenter.defaultCenter().addObserver(self, selector: "showBannerAd", name: "showadsID", object: nil)


    let scene = GameScene()
    // 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 = .AspectFit
    scene.anchorPoint = CGPoint(x: 0.5, y: 0.5)
    scene.size = skView.bounds.size
    skView.presentScene(scene, transition: transition)

为了在我想要的场景中显示它（对我来说这是 GameOver 场景），我这样做了：

override func didMoveToView(view: SKView) 

    showAds()
    // Rest of your code here...


func showAds()
    NSNotificationCenter.defaultCenter().postNotificationName("showadsID", object: nil)

基本上，这段代码会在场景之外创建一个横幅，当横幅加载并调用场景时，它会从底部向上滑动。当你切换场景时，它会再次偏移，当你回到那个场景时，它会再次从底部向上滑动。如果横幅没有加载，它就在屏幕外，所以不用担心它会显示一个白条。此外，如果它不加载以防万一（使其不可见），它会将 alpha 设置为 0。希望这会有所帮助。

【参考方案2】：

我用它在子视图中展示 iAd 横幅

var vc = self.view?.window?.rootViewController vc?.view.addSubview(adView!)

当我想在游戏中隐藏它时（因为 iAd 降低 FPS）我调用

adView!.removeFromSuperview()

当用户完成游戏后，只需添加

         var vc = self.view?.window?.rootViewController
        vc?.view.addSubview(adView!)

再次显示 iAd 横幅

但您需要在 GameViewController 中实现此代码

class GameViewController: ADBannerViewDelegate（你也需要这个） 也不要忘记在gameviewcontroller的顶部导入iAd 还将 iAd 框架导入到项目中

override func viewDidLoad() 
    self.ShowAd()

//也有这个视图 didLoad

     func ShowAd() 
        super.viewDidLoad()
        adView = ADBannerView(adType: ADAdType.Banner)
        adView!.delegate = self

    
    func bannerViewDidLoadAd(banner: ADBannerView!) 
        self.view.addSubview(adView!)
        self.view.layoutIfNeeded()
        println("Pass")
    

    func bannerView(banner: ADBannerView!, didFailToReceiveAdWithError error: NSError!) 
        adView!.removeFromSuperview()
        /*var alert = UIAlertController(title: "iAd Message", message:
            "iAd Fail To Load", preferredStyle: UIAlertControllerStyle.Alert)

        self.presentViewController(alert, animated: false, completion: nil)

        alert.addAction(UIAlertAction(title: "dismiss", style: UIAlertActionStyle.Default,
            handler: nil))
        self.view.layoutIfNeeded()*/
        println("fail")
