发布数据并从反应本机客户端订阅后，大约需要一分钟才能准备好订阅。如果我更新集合，则需要大约一分钟才能获取数据并触发 componentWillReceiveProps(newProps) 方法。集合只有很少的文档。

流星服务器代码：

import { Meteor } from 'meteor/meteor';
import { Accounts } from 'meteor/accounts-base';
import { ArtWorks } from './database/artworks';
import { Gallerys } from './database/gallerys';
import { PlayerData } from './database/playerdata';
import { Questions } from './database/questions';
import { Relics } from './database/relics';
import { RelicsOnMap } from './database/relicsonmap';



Meteor.startup(() => {





});
Meteor.publish('getRelicsOnMap', function getRelicsOnMap (){

  console.log("publishing...")
      return RelicsOnMap.find({});


    });

RelicsOnMap 集合：

import { Mongo } from 'meteor/mongo';

export const RelicsOnMap =  new Mongo.Collection('relicsonmap');

客户：

import React, { Component } from 'react';
import { View } from 'react-native';
import {
    Container,
    Header,
    Title,
    Content,
    Button,
    Item,
    Input,
    Body,
    Left,
    Right,
    Icon,
    Form,
    Text,
    Spinner,
    Toast 
  } from "native-base";
  import Meteor,{withTracker} from 'react-native-meteor';


 class ProfileScreen extends Component {
    constructor(props) {
        super(props);
    this.userData;

        this.state = {


        };
      }

    componentDidMount(){
     console.log(this.props)
    }
    componentWillReceiveProps(newProps){
        console.log(newProps)
    }




  render() {
    return (
        <Container> 
      <Text>This is Profile screen</Text>
      <Text>This is Profile screen</Text>




        </Container>
    );
  }

}
export default withTracker(params => {
    Meteor.subscribe('getRelicsOnMap');

     return {
       relicsOnMap: Meteor.collection('relicsonmap').find({})
     };
   })(ProfileScreen);

我在另一个组件中做 Meteor.connect 并且它成功了。这里有一个小视频我演示了这个问题： http ://sendvid.com/v5fqlurh

我发现 react natives 远程调试器会导致这个问题。当我没有连接到我的本地网络以通过 google chrome 进行调试时，一切都很好。我想这是一个错误。
