为什么我的 admob 插页式广告在 xcode 模拟器中可以正常工作，但在我的测试设备（iphone 4s 和 ipod 5th gen）上却不能正常工作？

Question

所以我有这个应用程序，它同时包含一个 admob 横幅广告和一个插页式广告。 横幅在所有屏幕上运行良好。 插页式广告应该只在一个屏幕上加载——当我在 xcode 模拟器中测试它时它加载得很好。 但是当我在我的 iPhone 和 iPod 上测试时，interestital 没有加载，我收到这个错误：请求错误：收到无效响应。 interstitialDidFailToReceiveAdWithError:请求错误：收到无效响应。 任何人以前都遇到过这种情况，或者可能知道为什么会发生这种情况？ 这是我正在使用的代码：

   // interstitial ad variable...
var interstitial: GADInterstitial?
var timer:NSTimer?
var loadRequestAllowed = true
let screen = UIScreen.mainScreen().bounds
let IS_IPAD = UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiom.Pad
var buttonHeight:CGFloat = 0.0
var buttonOffsetY:CGFloat = 0.0
let statusbarHeight:CGFloat = 20.0
var iAdSupported = false


       // load the interstitial
    //Admob Interstitial
    buttonHeight = IS_IPAD ? 30 : 20
    buttonOffsetY = statusbarHeight
    if !iAdSupported {
        interstitial = createAndLoadInterstitial()
    } // closes if !iAdSupported



//        presentInterstitial()
    timer = NSTimer.scheduledTimerWithTimeInterval(1, target:self, selector: Selector("presentInterstitial"), userInfo: nil, repeats: false)
    println("the timer made presentInterstitial run")




 //Interstitial func
func createAndLoadInterstitial()->GADInterstitial {
    println("createAndLoadInterstitial")
    var interstitial = GADInterstitial(adUnitID: "ca-app-pub-4471013071748494/2225255714")

    interstitial.delegate = self
    interstitial.loadRequest(GADRequest())

    return interstitial
} // closes createAndLoadInterstitial …

func presentInterstitial() {
    if let isReady = interstitial?.isReady {
        interstitial?.presentFromRootViewController(self)
        println("presentInterstitial function ran")
    } // closes if let isReady
} // closes presentInterstitial …



//Interstitial delegate
func interstitial(ad: GADInterstitial!, didFailToReceiveAdWithError error: GADRequestError!) {
    println("interstitialDidFailToReceiveAdWithError:\(error.localizedDescription)")
    //  ResultsBtn?.enabled = false
    interstitial = createAndLoadInterstitial()
} // closes interstitial …

您正在尝试在有机会加载之前展示您的插页式广告。 您的timer在一秒钟后触发func presentInterstitial 。 将其更改为更大的数字以提供加载间隙的时间。

import UIKit
import GoogleMobileAds

class ViewController: UIViewController, GADInterstitialDelegate {

    var admobInterstitial : GADInterstitial?
    var timer : NSTimer?

    override func viewDidLoad() {
        super.viewDidLoad()

        admobInterstitial = createAndLoadInterstitial()
        timer = NSTimer.scheduledTimerWithTimeInterval(5.0, target:self, selector: Selector("presentInterstitial"), userInfo: nil, repeats: false)
    }

    func createAndLoadInterstitial()->GADInterstitial {
        var interstitial = GADInterstitial(adUnitID: "yourAdMobADUnitID")
        interstitial.delegate = self
        interstitial.loadRequest(GADRequest())
        return interstitial
    }

    func presentInterstitial() {
        if let isReady = admobInterstitial?.isReady {
            admobInterstitial?.presentFromRootViewController(self)
        }
    }

    func interstitial(ad: GADInterstitial!, didFailToReceiveAdWithError error: GADRequestError!) {
        println("interstitialDidFailToReceiveAdWithError:\(error.localizedDescription)")
        admobInterstitial = createAndLoadInterstitial()
    }

附带说明一下，您不应为局部变量赋予与全局变量相同的名称。
