    var ds = new ListView.DataSource({rowHasChanged:(r1,r2) => r1 != r2});

    //返回数据
    return{
      dataSource:ds.cloneWithRows(Wine),
    };
  },

  //设置render
  render(){
    return (
        <ListView
            dataSource ={this.state.dataSource}
            renderRow = {this.renderRow}
        />
    );
  },

  //返回具体的cell
  renderRow(rowData, sectionID, rowID, highlightRow){
    return(
    <TouchableOpacity activeOpacity={0.5} onPress={()=>{AlertIOS.alert('click'+rowID)}}>
        <View style={styles.cellViewStyle}>
            <Image source={{uri:rowData.image}} style={styles.leftImgStyle}/>

            <View style={styles.rightViewStyle}>
              <Text style={styles.topTitleStyle}>
                {rowData.name}
              </Text>
