  • React Native 中 跨页面间通信解决方案之 react-native-event-bus

    https://github.com/crazycodeboy/react-native-event-bus

    用法: A页面和B页面中都有相同的列表,点击B页面中的收藏按钮,A页面会跟着更新

    import EventBus from 'react-native-event-bus';
    constructor(props){
        super(props);
        const {tabLabel} = this.props;
        this.storeName = tabLabel;
        this.isFavoriteChanged = false;
      }
    
      componentDidMount(){
        this.loadData();
        EventBus.getInstance().addListener(EventTypes.favorite_changed_popular,this.favoriteChangeListener = ()=>{
          this.isFavoriteChanged = true;
        });
        EventBus.getInstance().addListener(EventTypes.bottom_tab_select,this.bottomTabSelectListener = (data)=>{
          if(data.to === 0 && this.isFavoriteChanged){
            this.loadData(null,true);
          }
        });
      }
    
      componentWillUnmount(){
        EventBus.getInstance().removeListener(this.favoriteChangeListener);
        EventBus.getInstance().removeListener(this.bottomTabSelectListener);
      }
    onFavorite(item,isFavorite){
        
        FavoriteUtil.onFavorite(this.favoriteDao,item,isFavorite,this.props.flag);
        if(this.storeName === FLAG_STORAGE.flag_popular){
          EventBus.getInstance().fireEvent(EventTypes.favorite_changed_popular);
        }
        else{
          EventBus.getInstance().fireEvent(EventTypes.favorite_changed_trending );
        }
      }
