swift - 优先考虑 iAd 而非 adMob SpriteKit/Swift

Question

我将 iAd 和 adMob 集成到我的游戏中，adMob 代码仅在 iAd 加载失败时运行。如果 iAd 没有加载第一个广告失败，则说明它工作正常。当 iAd 加载失败时，Admob 会正常工作。但是，当 iAd 失败但随后加载下一个广告时，adMob 横幅仍然存在并且不会显示 iAd。即使 adMob 已经加载，我如何才能加载 iAd？此外，当 adMob 代码被注释掉时，iAd 横幅在加载失败后加载正常。顺便提一句，如何更改模拟器中 adMob 广告的填充率？谢谢。这是我在 GameViewController 中的代码(iAd 在 gameScene 中调用):

import UIKit
import SpriteKit
import iAd
import GoogleMobileAds

class GameViewController: UIViewController, ADBannerViewDelegate {

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

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) */

    UIiAd.setTranslatesAutoresizingMaskIntoConstraints(false)
    UIiAd.delegate = self
    self.view.addSubview(UIiAd)
    let viewsDictionary = ["bannerView":UIiAd]
    view.addConstraints(NSLayoutConstraint.constraintsWithVisualFormat("H:|[bannerView]|", options: .allZeros, metrics: nil, views: viewsDictionary))
    view.addConstraints(NSLayoutConstraint.constraintsWithVisualFormat("V:[bannerView]|", options: .allZeros, metrics: nil, views: viewsDictionary))

}

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()

    println("iAd work")
}

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

    googleBannerView = GADBannerView(adSize: kGADAdSizeSmartBannerLandscape)
    googleBannerView.adUnitID = "ca-app-pub-3940256099942544/2934735716"
    googleBannerView.rootViewController = self
    var request: GADRequest = GADRequest()
    googleBannerView.loadRequest(request)

    googleBannerView.frame = CGRectMake(0, view.bounds.height - googleBannerView.frame.size.height, googleBannerView.frame.size.width, googleBannerView.frame.size.height)

    self.view.addSubview(googleBannerView!)

    println("iAd fail")
}

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, 2048, 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(size: CGSize(width: 2048, height: 1356))
    let skView = self.view as! SKView
    skView.showsFPS = true
    skView.showsNodeCount = true
    skView.ignoresSiblingOrder = true
    scene.scaleMode = SKSceneScaleMode.AspectFill
    skView.presentScene(scene)
}

func bannerViewActionShouldBegin(banner: ADBannerView!, willLeaveApplication willLeave: Bool) -> Bool {

    println("Clicked")
    //  let skView: SKView = self.view as! SKView
    //  skView.scene!.paused = true
    return true
}
/*    func bannerViewActionDidFinish(banner: ADBannerView!) {
let skView: SKView = self.view as! SKView
skView.scene!.paused = false
} */

override func prefersStatusBarHidden() -> Bool {
    return true
}

}

Answer 1

当 iAd 在 bannerViewDidLoadAd(banner: ADBannerView!) 中收到广告时，您并未隐藏 AdMob 横幅。因此，您的 iAd 横幅实际上显示在 AdMob 横幅后面。

或者，您可以在 viewDidLoad 中同时创建 iAd 和 AdMob 横幅，并根据 iAd 是否收到广告隐藏或显示它们。您的 iAd 委托(delegate)方法最终看起来与此类似:

func bannerViewDidLoadAd(banner: ADBannerView!) {
    UIView.beginAnimations(nil, context: nil)
    // Show iAd
    UIiAd.alpha = 1.0
    // Hide AdMob
    googleBannerView.alpha = 0.0
    UIView.commitAnimations()
}

func bannerView(banner: ADBannerView!, didFailToReceiveAdWithError error: NSError!) {
    UIView.beginAnimations(nil, context: nil)
    // Hide iAd
    UIiAd.alpha = 0.0
    // Show AdMob
    googleBannerView.alpha = 1.0
    UIView.commitAnimations()
}
