React/RCTBridgeModule.h file not found

0.34版本後要求的方法 ，所以用第三方容易出錯

Older way of importing react-native header files: 
 #import <React/RCTBridgeModule.h>
 #import <React/RCTLog.h>

New & correct way of importing react-native header files: 
 #import "RCTBridgeModule.h"
 #import "RCTLog.h"

unable to load script from assets index.android.bundle

新版本編譯有問題

    1.(in project directory) mkdir android/app/src/main/assets
    2.react-native bundle --platform android --dev false --entry-file index.android.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res
    3.react-native run-android

cannot read property 'string' of undefined

property 要求字串沒有定義

0.49 之前都是正常的

static propTypes = {
    pagetype:React.PropTypes.string.isRequired
};

0.49後要改
因為React 沒有 proptypes , 所以要提出來使用其他 prop-types

import PropTypes from 'prop-types';
static propTypes = {
    pagetype:PropTypes.string.isRequired
};
