React Native Navigator

a. react-native版本从0.29.0升级到0.45.1后出现下面的错误：

Navigator is deprecated and has been removed from this package.
It can now be installed and imported from react-native-deprecated-custom-components

可知Navigator已被废弃，并从react-native包中移除，若要继续使用则需要改为：

import {Navigator} from 'react-native-deprecated-custom-components';

b. 自定义Navigator 的 configureScene，如下：

CustomizeConfigScene.js:

import {Navigator} from 'react-native-deprecated-custom-components';export var PushFromRightNoGestures = {    ...Navigator.SceneConfigs.PushFromRight,    gestures: {      pop: false,    },};

在引用的地方如下：

import React, { Component } from 'react';import {  AppRegistry,  View,  StatusBar,} from 'react-native';import {Navigator} from 'react-native-deprecated-custom-components';import {PushFromRightNoGestures} from './CustomizeNavigatorSceneConfig.js';import LoginUI from './LoginUI.js';class AweSomeProject extends Component {  render() {    let defaultName = 'LoginUI';    let defaultComponent = LoginUI;    return (      <Navigator        initialRoute={{name: defaultName, component: defaultComponent}}        configureScene={          (route) => {            //禁止手势返回            return PushFromRightNoGestures;          }        }        renderScene={          (route, navigator) => {            let Component = route.component;            return <Component {...route.params} navigator={navigator}/>          }        }/>    );  }}AppRegistry.registerComponent('AweSomeProject', () => AweSomeProject);
