开发日记

在使用了react-native-admob插件之后，第二次始终是指向前面的一个this对象。 调试了蛮久，发现是因为我每次调用广告的时候都会addListener，然后插件其实会存起来。
首先我们应该调用
removeAllListeners();

if (global.loadingReward) {
  console.log('正在加载广告，跳过!!!');
  return;
}
this.hasRecv = false;
console.log('开始加载广告!!!');
global.loadingReward = true;
AdMobRewarded.setTestDevices([AdMobRewarded.simulatorId]);
//AdMobRewarded.setAdUnitID('ca-app-pub-9280092940596395/3561826862');
AdMobRewarded.setAdUnitID('ca-app-pub-3940256099942544/5224354917');
AdMobRewarded.removeAllListeners();
AdMobRewarded.addEventListener('rewarded', reward => {
  if (this.hasRecv){
    return;
  }
  this.hasRecv = true;
  console.log('AdMobRewarded => rewarded', reward);
  global.loadingReward = false;
  successCallback();
});
AdMobRewarded.addEventListener('adFailedToLoad', error => {
  global.loadingReward = false;
  console.log('failed:', error);
  errorCallback();
});
AdMobRewarded.addEventListener('adClosed', ()=>{
  console.log('adClosed!!!');
  if(global.loadingReward == false){
    return;
  }
  global.loadingReward = false;
  errorCallback();
})
AdMobRewarded.requestAd()
  .then(() => AdMobRewarded.showAd())
  .catch(error => {
    global.loadingReward = false;
    console.log('failed:', error);
    errorCallback();
  });
