SWIFT ADMOB：加载失败：请求错误：无广告显示

Question

我实际上是在Swift中使用AdMob Reward开发iOS应用，当我尝试使用模拟器（iPhone 6、6s，7、8等）构建应用时，广告有效，并且我也收到以下消息：

收到了基于奖励的视频广告。

但是（因为总是有一个but），当我在自己的设备（iPhone 6）上构建应用程序时不起作用，并且出现以下错误消息：“基于奖励的视频广告无法加载：请求错误：没有要显示的广告。” 这是我的代码（很明显，我是通过“奖励广告Mob入门”中给出的示例更改广告ID的，但在我的应用中，我使用的是广告ID）。 我为示例选择的示例ID：ca-app-pub-3940256099942544 / 1712485313

let request = GADRequest()
    request.testDevices = [ kGADSimulatorID,"ca-app-pub-3940256099942544/1712485313"];
    rewardBasedVideo = GADRewardBasedVideoAd.sharedInstance()
    rewardBasedVideo?.delegate = self
    if rewardBasedVideo?.isReady == false {
        rewardBasedVideo?.load(GADRequest(), withAdUnitID: "ca-app-pub-3940256099942544/1712485313")
        adRequestInProgress = true
    }

并且

//ADMOB
// MARK: GADRewardBasedVideoAdDelegate implementation
func rewardBasedVideoAd(_ rewardBasedVideoAd: GADRewardBasedVideoAd,
                        didFailToLoadWithError error: Error) {
    adRequestInProgress = false
    print("Reward based video ad failed to load: \(error.localizedDescription)")
}

func rewardBasedVideoAdDidReceive(_ rewardBasedVideoAd: GADRewardBasedVideoAd) {
    adRequestInProgress = false
    print("Reward based video ad is received.")
}

func rewardBasedVideoAdDidOpen(_ rewardBasedVideoAd: GADRewardBasedVideoAd) {
    print("Opened reward based video ad.")
}

func rewardBasedVideoAdDidStartPlaying(_ rewardBasedVideoAd: GADRewardBasedVideoAd) {
    print("Reward based video ad started playing.")
}

func rewardBasedVideoAdDidClose(_ rewardBasedVideoAd: GADRewardBasedVideoAd) {
    print("Reward based video ad is closed.")
}

func rewardBasedVideoAdWillLeaveApplication(_ rewardBasedVideoAd: GADRewardBasedVideoAd) {
    print("Reward based video ad will leave application.")
}

func rewardBasedVideoAd(_ rewardBasedVideoAd: GADRewardBasedVideoAd,
                        didRewardUserWith reward: GADAdReward) {
    print("Reward received with currency: \(reward.type), amount \(reward.amount).")
}
//ADMOB!

Answer 1

首先，您应该查看日志以获取真实设备的标识符

然后修复该行：

request.testDevices = [...]

像使用模拟器一样替换...，然后将其替换为真实设备的if，然后您会看到一个测试广告，您使用了广告单元ID，而不是设备ID
