Question

我有一个食谱详细信息屏幕，我想在每次用户进入以查看食谱详细信息时添加一个插页式广告，但我希望将其限制为每3次显示一次，因为当用户退出并重新输入时食谱或其他食谱再次显示广告，这是我不想要的。

我该怎么办？

 import { AdMobInterstitial, setTestDeviceIDAsync } from 'expo-ads-admob';

 export default class RecipeDetails extends Component {

  initAds = async () => {

  const INTERSTITIAL_ID = Platform.OS == "ios" ? ConfigApp.IOS_INTERSTITIAL_ID : ConfigApp.ANDROID_INTERSTITIAL_ID;

  AdMobInterstitial.setAdUnitID(INTERSTITIAL_ID);
  await setTestDeviceIDAsync(ConfigApp.TESTDEVICE_ID);
  await AdMobInterstitial.requestAdAsync({ servePersonalizedAds: true});
  await AdMobInterstitial.showAdAsync();

  };

  componentDidMount() {

       this.initAds();

     }

  render() {

    return (
<View>
// content
</View>
    );
  }

我认为您每次致电广告时都可以使用async-storage来存储时间。并在播放广告之前阅读您存储的每一次以比较它是否等于三？

存储数据（时间）

storeData = async () => {
  try {
    await AsyncStorage.setItem('@storage_Key', 'stored value')//
  } catch (e) {
    // saving error
  }
}

读取数据（次）

getData = async () => {
  try {
    const value = await AsyncStorage.getItem('@storage_Key')
    if(value !== null) {
      // value previously stored
    }
  } catch(e) {
    // error reading value
  }
}

-------------- update ----------------您想要的东西-------

initAds = async () => {

  const INTERSTITIAL_ID = Platform.OS == "ios" ? ConfigApp.IOS_INTERSTITIAL_ID : ConfigApp.ANDROID_INTERSTITIAL_ID;
  try{
      const value = await AsyncStorage.getItem('play_ad_times')
      if(value !== null) {
          if(value == "3"){ 
             await AsyncStorage.setItem('play_ad_times', "1"); //If three times back to one times and play once

             AdMobInterstitial.setAdUnitID(INTERSTITIAL_ID);
             await setTestDeviceIDAsync(ConfigApp.TESTDEVICE_ID);
             await AdMobInterstitial.requestAdAsync({ servePersonalizedAds: true});
             await AdMobInterstitial.showAdAsync();

          }else{
             var temp = parseInt(value)+1;
             await AsyncStorage.setItem('play_ad_times', temp.toString() );
          }
      // value previously stored
      }else{
          //first time in
          await AsyncStorage.setItem('play_ad_times', "1"); //Set time 1
          AdMobInterstitial.setAdUnitID(INTERSTITIAL_ID);
          await setTestDeviceIDAsync(ConfigApp.TESTDEVICE_ID);
          await AdMobInterstitial.requestAdAsync({ servePersonalizedAds: true});
          await AdMobInterstitial.showAdAsync();


          }
      }catch(e) {
        // error reading value
        await AsyncStorage.setItem('play_ad_times', "1");
      }

};

如何在React Native中进入屏幕每3次显示一次广告？
