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 );
}
}
