原程序是这样写的，然后一直出现错误，找不到PropTypes，
- import React,{Component } from ‘react‘;
- import {
- View,
- Text,
- Image,
- TouchableWithoutFeedback,
- PropTypes,
- StyleSheet
- } from ‘react-native‘;
替换成下面的代码就可以成功解决错误。。
- import React,{Component,PropTypes} from ‘react‘;
- import {
- View,
- Text,
- Image,
- TouchableWithoutFeedback,
-
- StyleSheet
- } from ‘react-native‘;
React Native报错undefined is not an object（evaluating ‘_reactnative.propTypes’）解决办法
