无法使用React Native FCM触发远程推送通知

Question

我在Feed组件内的构造函数中使用firebase .on（'value'）侦听器。当将值添加到firebase数据库时，它将触发，而当我使用this.showLocalNotification（）时，它将起作用。但是，当我使用this.sendRemoteNotification（）时，没有骰子。由于我可以在该函数中管理日志数据，因此该函数已被关闭，但是当应用程序处于前台，后台或完全不打开时，它无法显示通知。我已经在Xcode中检查了所有功能，正在iOS 8设备上运行此功能，并且正在使用react-native-fcm 16.0.0。

这是我的Feed组件，其构造函数包括firebase侦听器和推送通知功能。

registerKilledListener();


class Feed extends Component {
  static navigationOptions = {
    tabBarLabel: "Active Jobs",
    tabBarIcon: ({ tintColor }) => (
      <Icon name="newspaper" size={28} color={COLOR.ICON} />
    )
  }; // navigationOptions
  constructor(props) {
    super(props)

    this.state = {
      token: "",
      tokenCopyFeedback: ""
    }


    database.ref("OpenRequests/").on("value", snapshot => {
      let data = snapshot.val();

      let obj = data[Object.keys(data)[Object.keys(data).length - 1]]

      //  this.showLocalNotification(obj)
      this.sendRemoteNotification(obj)

    });

  }

  async componentWillMount() {

    console.log(this.props.navigation)
    registerAppListener(this.props.navigation);
    FCM.getInitialNotification().then(notif => {
      this.setState({
        initNotif: notif
      });
      if (notif && notif.targetScreen === "detail") {
        setTimeout(() => {
          this.props.navigation.navigate("Detail");
        }, 500);
      }
    });

    try {
      let result = await FCM.requestPermissions({
        badge: false,
        sound: true,
        alert: true
      });
    } catch (e) {
      console.error(e);
    }

    FCM.getFCMToken().then(token => {
      // console.log('Setting token: ', token)
      // console.log("TOKEN (getFCMToken)", token);
      this.setState({
        token: token || ""
      });
    });

    if (Platform.OS === "ios") {
      FCM.getAPNSToken().then(token => {
        // console.log("APNS TOKEN (getFCMToken)", token);
      });
    }
    FCM.createNotificationChannel({
      id: 'default',
      name: 'Default',
      description: 'used for example',
      priority: 'high'
    })

    // topic example
    // FCM.subscribeToTopic('sometopic')
    // FCM.unsubscribeFromTopic('sometopic')
  }

  sendRemoteNotification(data) {
    let body;
    if (Platform.OS === "android") {
      body = {
        to: this.state.token,
        data: {
          custom_notification: {
            title: "Simple FCM Client",
            body: JSON.stringify(data),
            sound: "default",
            priority: "high",
            show_in_foreground: true,
            // targetScreen: "feed"
          }
        },
        priority: 10
      };
    } else {
      body = {
