原来写的代码太乱，自己精简了一下，有需要的可以参考下，互相学习

  var React = require('react');

  var {DEV} = Util;
  var TEMPData = [

  },
  img:{

  module.exports = Home;

• Util文件代码如下

'use strict';

/**
* 帮助工具类

*/

var React = require('react');
var ReactNative = require('react-native');
var {
Alert,
Platform,
Dimensions,
PixelRatio,
NativeModules,
} = ReactNative;
var Store = require('react-native-simple-store');
var Icon = require('react-native-vector-icons/Ionicons');
var Util ={
DEV:true,
//单位像素比
pixel: 1 / PixelRatio.get(),
//屏幕尺寸
size: {
width: Dimensions.get('window').width,
height: Dimensions.get('window').height
},
};
module.exports = Util;
