react -native高仿美团V1.1

V1.1目前在V1的基础上稍作修改，如猜你喜欢界面的排版布局和目前真实的美团是几乎一样的
https://github.com/targetcloud/Meituan


需要注意的是「新客减4元」这个黄色小框是根据不同情况来处理的，在返回的JSon中的字典中可能有或没有这个键，所以要判断一下

<Text style={{color:'orange',borderWidth:0.5,borderColor:'orange',  borderRadius:4, padding:0.1}}>{(row.campaign)==null?'': row.campaign.tag}</Text>

具体功能封装了一个function

renderCampaignTag(campaign){
if (campaign == null){
return <Text/>
}else {
return <Text style={{color:'orange',borderWidth:0.5,borderColor:'orange',  borderRadius:4, padding:0.1}}>{campaign.tag}</Text>
}
},

全部代码如下：

其他升级的细小功能点不再详述，直接看下面图吧，觉得好github上STAR（我会在V1.2版本更新时接近目前最新版美团）
