React Native(Expo)替换AdMob生产AdUnit ID后TestFlight无广告显示

背景 #

我用Expo和react-native-google-mobile-ads在React Native应用里集成了AdMob。本地用测试AdUnit ID（ca-app-pub-3940256099942544/6978759866）时，模拟器里广告显示正常，但切换成AdMob提供的生产AdUnit ID（ca-app-pub-xxx/xxx）并通过Expo构建后，Expo Go和TestFlight里都看不到广告。

配置信息 #

app.json配置 #

{
  "expo": {
    ...
    "plugins": [
      [
        "react-native-google-mobile-ads",
        {
          "androidAppId": "ca-app-pub-xxx~xxx",
          "iosAppId": "ca-app-pub-xxx~xxx"
        }
      ]
    ],
    "ios": {
      ...
      "infoPlist": {
        "SKAdNetworkItems": [
          {
            "SKAdNetworkIdentifier": [
              "cstr6suwn9.skadnetwork",
              "4fzdc2evr5.skadnetwork",
              ...
            ]
          }
        ]
      }
    }
  }
}

AdMob组件代码 #

import { RewardedInterstitialAd, RewardedAdEventType, TestIds, AdEventType } from 'react-native-google-mobile-ads';
import React, { useEffect, useState } from 'react';
import { View, StyleSheet } from 'react-native';

const adUnitId = 'ca-app-pub-xxx/xxx'; // Production Ad Unit ID

const rewardedInterstitial = RewardedInterstitialAd.createForAdRequest(adUnitId, {
  requestNonPersonalizedAdsOnly: true,
  keywords: ['fashion', 'clothing'],
});

const RewardedInterstitialAdComponent = () => {
  const [loaded, setLoaded] = useState(false);

  useEffect(() => {
    const unsubscribeLoaded = rewardedInterstitial.addAdEventListener(RewardedAdEventType.LOADED, () => {
      console.log('Ad loaded');
      setLoaded(true);
    });

    const unsubscribeEarned = rewardedInterstitial.addAdEventListener(RewardedAdEventType.EARNED_REWARD, (reward) => {
      console.log('User earned reward', reward);
    });

    const unsubscribeClosed = rewardedInterstitial.addAdEventListener(AdEventType.CLOSED, () => {
      rewardedInterstitial.load();
    });

    rewardedInterstitial.load();

    return () => {
      unsubscribeLoaded();
      unsubscribeEarned();
      unsubscribeClosed();
    };
  }, []);

  if (!loaded) {
    return null;
  }

  rewardedInterstitial.show();

  return <View style={styles.container} />;
};

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
  },
});

export default RewardedInterstitialAdComponent;

已知问题 #

• 本地测试AdUnit ID在模拟器中广告显示正常
• 切换生产AdUnit ID后，TestFlight和生产构建的Expo Go中均无广告显示
• 已确认app.json和AdMob控制台的AdUnit ID完全一致
• 不确定是配置问题还是TestFlight中的正常现象

疑问 #

1. TestFlight中（应用审核期间）不显示真实广告是否属于正常行为？
2. 应用上架App Store后广告是否会正常工作，还是我遗漏了某些配置？

解答 #

关于TestFlight中无真实广告的问题 #

这是正常现象。AdMob会自动限制测试环境（包括TestFlight构建）中的真实广告投放，核心目的是避免无效点击干扰广告收益统计，同时防止测试行为触发政策违规。TestFlight环境下即便配置生产AdUnit ID，也只会返回测试广告或无广告填充。

上架后的广告是否正常 #

只要完成以下配置，上架App Store后广告应该能正常工作：

• 确认AdMob控制台中，应用ID（ca-app-pub-xxx~xxx）与app.json里配置的androidAppId/iosAppId完全匹配
• 确认生产AdUnit ID已关联到对应应用，且AdMob控制台中该应用状态为已批准（未批准的应用无法投放真实广告）
• iOS端SKAdNetworkItems配置完整（当前配置已包含AdMob核心SKAdNetwork ID，确保无遗漏）
• 确认应用未违反AdMob政策，否则上架后仍可能被限制广告投放

额外检查点 #

• 可以在生产构建中添加广告加载失败监听，通过日志排查具体问题：

  const unsubscribeFailed = rewardedInterstitial.addAdEventListener(AdEventType.FAILED_TO_LOAD, (error) => {
    console.log('Ad failed to load:', error);
  });
  

  失败日志会明确原因，比如广告填充不足、配置错误等。
• Expo Go属于测试环境，和TestFlight一样，仅支持测试AdUnit ID，无法加载生产广告。
