OneSignal-在打开应用程序（在前台）时不显示推送通知

Question

我在我的应用程序中使用react-native-onesignal，并且在不使用该应用程序（前台）的情况下，推送通知显示的时间为100％。但是，在打开应用程序时，不会显示通知，也不会触发侦听器。

• 我正在使用通过yarn添加的OneSignal React-Native SDK v3.2.7
• macOS版本：Mojave
• XCode版本：9.4.1
• 设备：运行iOS 11的Apple iPhone 6

我的代码基于RNOneSignal example的代码：

class Root extends Component {
  constructor(props) {
    super(props)
    this.onReceived = this.onReceived.bind(this)
    this.onOpened = this.onOpened.bind(this)
    this.onIds = this.onIds.bind(this)
  }
  componentWillMount() {
    console.warn(new Date())
    console.warn('componentWillMount')
    OneSignal.setLogLevel(7, 0);
    OneSignal.inFocusDisplaying(2);
    OneSignal.init(MY_APP_ID);
    OneSignal.configure({});
    OneSignal.addEventListener('received', this.onReceived);
    OneSignal.addEventListener('opened', this.onOpened);
    OneSignal.addEventListener('ids', this.onIds);
  }

  componentWillUnmount() {
    console.warn('componentWillUnmount')
    OneSignal.removeEventListener('received', this.onReceived);
    OneSignal.removeEventListener('opened', this.onOpened);
    OneSignal.removeEventListener('ids', this.onIds);
  }

  onReceived(notification) {
    console.warn("Notification received: ", notification);
  }

  onOpened(openResult) {
    console.warn('Message: ', openResult.notification.payload.body);
    console.warn('Data: ', openResult.notification.payload.additionalData);
    console.warn('isActive: ', openResult.notification.isAppInFocus);
    console.warn('openResult: ', openResult);
  }

  onIds(device) {
    console.warn('Device info: ', device);
  }
    render(){
        return(
            <Provider store={store}>
                <App />
            </Provider>
        );
    }
}

PS：：当我在RNOneSignal example app上使用相同的应用程序ID时，一切正常（在后台和前台都显示通知）
