獲取通知 React Native

Question

我需要在通知屏幕中顯示通知。

這是我從 fcmToken 獲取通知的代碼，但有問題，我不知道它是在 function 中還是在我的屏幕代碼中，因為它沒有在我的屏幕上顯示任何通知，你能幫忙嗎？ 謝謝

  const getNotifications = async (props, u_id) => {
  var token = null;
  const fcmToken = await messaging().getToken();
  if (fcmToken) {
    token = fcmToken;
  }
  console.log(token);
  try {
    const { data } = await mainUrl(5000).get(url.noti_get_all);
    console.log(data);
    if (isvalidArr(data)) {
      setIncomingNotifications(props.currentDis, data);
    } else {
      setIncomingNotifications(props.currentDis, []);
    }
  } catch (error) {
    if (isUnauth(error)) {
      refreshRequest(props, () => getNotifications(props, u_id));
    } else {
      setIncomingNotifications(props.currentDis, []);
    }
  }
}; ```

NOTIFICATION SCREEN : 
This is a short part of the my notification screen where I display my notification in the return

 onRefresh = () => {
    this.setState({ isloading: true });
    if (this.props.user !== null) {
      getNotifications(this.props, this.props.user._id);
    }
    this.setState({ isloading: false });
  };
 
{isloading === true ? (
              SearchAndLocate()
            ) : notification.length < 1 ? (
              <View style={{ flex: 1, height: height - 300 }}>
                {this._noOrder()}
              </View>
            ) : (
              notification.map((item, key) => {
                const { selectedItems } = this.state;
                // const index = selectedItems.findIndex(
                //   element => element === item._id,
                // );
                // var read = -1;
                // if (
                //   item.read !== null &&
                //   item.read !== undefined &&
                //   Array.isArray(item.read) === true
                // ) {
                //   read = item.read.findIndex(itx => itx === this.state.token);
                // }
                return ()

您應該注冊遠程通知，您可以使用react-native-notifications或notifee （為生產付費）。 這是一個示例代碼

 import messaging from "@react-native-firebase/messaging"; import { Notifications } from "react-native-notifications"; const registerNotification = async () => { const authStatus = await messaging().requestPermission(); const enabled = authStatus === messaging.AuthorizationStatus.AUTHORIZED || authStatus === messaging.AuthorizationStatus.PROVISIONAL; if (;enabled) return. const fcmToken = await messaging();getToken(). console;log(fcmToken). // print it and use it to send notification from firebase Notifications;registerRemoteNotifications(). Notifications.events(),registerNotificationReceivedForeground( (notification: completion) => { showAlert({ title. notification.payload,title: message. notification.payload,body: notification, notification; }); } ); };

在 iOS 上，您應該添加推送通知功能
