iOS.ReactNative-5-make-react-native-to-support-dynamically-update

基于React Native来实现App的热更新

热更新: 类似Hot-Patching，在程序不发布版本的前提下，对部分功能或者全部功能进行修改或者升级。

JSX

1. JSX简介

1.1 https://jsx.github.io/

1.2 Tutorial: JSX

"JSX is a preprocessor step that adds XML syntax to JavaScript. "

"Just like XML, JSX tags have a tag name, attributes, and children. "

"JSX lets you create JavaScript objects using HTML syntax. " Ref [5]

"JSX is not required to use React." Ref[5]

JSX 官方文档: https://facebook.github.io/react/docs/jsx-in-depth.html

live Babel REPL: 将JSX转换为JavaScript代码的REPL。https://babeljs.io/repl/

JSX gotchas for some key differences. https://facebook.github.io/react/docs/jsx-gotchas.html

http://buildwithreact.com/tutorial/jsx

http://jsbin.com/qucecahako/1/edit?html,css,js,output

1.3 JSX in Depth

JSX is a JavaScript syntax extension that looks similar to XML.

https://facebook.github.io/react/docs/jsx-in-depth.html

可以用Babel将JSX转换为JavaScript。

1.4 JSX 规范

 Setting up new React Native app in /Users/XiaoKL/Projects/PrivateProject/react-native/HelloWorld
 To run your app on iOS:
    Open /Users/XiaoKL/Projects/PrivateProject/react-native/HelloWorld/ios/HelloWorld.xcodeproj in Xcode
    Hit the Run button
 To run your app on Android:
    Have an Android emulator running (quickest way to get started), or a device connected
    cd /Users/XiaoKL/Projects/PrivateProject/react-native/HelloWorld
    react-native run-android

react-native init 命令的输出

Q: 如何获得某个版本的React-Native的代码？

A:

B): 创建Podfile

$ pod init

C): 安装React-Native Library

1. 在Podfile中添加以下内容:

 # Depending on how your project is organized, your node_modules directory may be
 # somewhere else; tell CocoaPods where you've installed react-native from npm
 pod 'React', :path => '../node_modules/react-native', :subspecs => [  // A
   'Core',
   'RCTImage',
   'RCTNetwork',
   'RCTText',
   'RCTWebSocket',
   # Add any other subspecs you want to use in your project
 ]

A: :path 用来将本地的代码通过Pod方式进行安装. :path 的值指定了本地代码相对Podfile的相对路径。例如在Demo中 :path 取值为:

:path => '../HelloWorld/node_modules/react-native'

2. 运行命令 $ pod install

D): 打包js代码

react-native bundle

 react-native bundle --entry-file index.ios.js --platform ios --bundle-output EmbededReactNative.jsbundle

react-native bundle 命令说明 [TODO]

NPM: Node Package Manager

"npm is the  package manager for the Node JavaScript platform.  It puts modules in

RCTRootView & RCTView

1. RCTRootView

Native Code(Objective-C Code)和React Native间的接口由RCTRootView暴露出来。

RCTRootView中只包含RCTRootContentView对象，该对象是实际的React Native组件的容器。

 @interface RCTRootContentView : RCTView <RCTInvalidating>
 
 @property (nonatomic, readonly) BOOL contentHasAppeared;
 
 - (instancetype)initWithFrame:(CGRect)frame bridge:(RCTBridge *)bridge;
 
 @end

2. RCTView

RCTView是ReactNative中UI容器组件(可以包含其它UI对象的组件)的父类，其直接子类包含:

RCTTextView RCTScrollView RCTRootContentView RCTWebView

TODO: UML图

3. RCTViewNodeProtocol

RCTViewNodeProtocol: Logical node in a tree of application components.

4. RCTBridge
