一 安装

1. 安装

在你的项目根目录下运行以下命令：(根目录通常为带有package.json的)

npm install -g react-native-update-cli rnpm

npm install --save react-native-update

2. 手动和自动link

a. 如果项目为纯RN项目执行以下命令

react-native link react-native-update

b. 如果是RN植入到iOS原生项目,经测试link无用,用cocopods自动链接（重点，我本人就在这一步卡住了，如果不按照这个步骤会报错 'React/RCTDefines.h' file not found）

找到node_modules->react-native-update

touch react-native-update.podspec

在react-native-update.podspec这个文件中编辑

require "json"

package = JSON.parse(File.read(File.join(__dir__, "package.json")))

Pod::Spec.new do |s|

s.name = "react-native-update"

s.version = package["version"]

s.summary = "hot update for react-native"

s.author = "author (https://github.com/reactnativecn)"

s.homepage = "https://github.com/reactnativecn/react-native-pushy"

s.license = "MIT"

s.platform = :ios, "7.0"

s.source = { :git => "https://github.com/reactnativecn/react-native-pushy.git", :tag => "#{s.version}" }

s.source_files = "ios/**/*.{h,m,c}"

s.libraries = "bz2"

s.dependency "React"

end

在Podfile中添加路径

pod 'react-native-update' , :path => './node_modules/react-native-update'

      pod update

3. 配置Bundle URL(iOS)

4. 在工程target的Build Phases->Link Binary with Libraries中加入libz.tbd、libbz2.1.0.tbd

5. 工程中添加代码

#import "RCTHotUpdate.h"

#if DEBUG

  // 原来的jsCodeLocation

  jsCodeLocation = [NSURL URLWithString:@"http://localhost:8081/index.ios.bundle?platform=ios&dev=true"];

#else

  jsCodeLocation=[RCTHotUpdate bundleURL];

#endif

6. iOS的ATS例外配置

右键点击Info.plist，选择open as - source code

<key>NSAppTransportSecurity</key>

<dict>

<key>NSExceptionDomains</key>

<dict>

    <key>reactnative.cn</key>

    <dict>

        <key>NSIncludesSubdomains</key>

        <true/>

        <key>NSExceptionAllowsInsecureHTTPLoads</key>

        <true/>

    </dict>

</dict>

</dict>

这些步骤完成可以解决添加pushy后 'React/RCTDefines.h' file not found错误
