ReactNative集成网易云信IM Demo（iOS版）

本文已 ReactNative 集成 NIM_iOS_Demo_v4.2.0 为例。Xcode版本为9.0
本人是在已有的ReactNative(以下简称RN)工程下集成云信IM（其他各版本集成方式大同小异）

1. 使用 cocoapods 来安装网易云信依赖

1.首先在 terminal 里进入到自己RN项目ios目录下， 运行 pod init ，（如果电脑没安装cocoapods的，请先安装 cocoapods ），运行完成后，会在当前所在目录下生成 Podfile 文件。

2. 下载云信 IM demo 源码
   前往 网易云信 下载iOS版 云信IM demo

2. 在 Podfile 里添加网易云信的依赖

1. terminal 进入到 RN ios目录下执行 pod init，执行后在 ios 目录下生成 Podfile 文件。

2. 在下载好的云信demo里 NIMDemo 目录下找到 Podfile 文件，复制文件里面的内容到自己的 Podfile 文件里。此部完成后的结果如下

source \'https://github.com/CocoaPods/Specs.git\'
platform :ios, \'9.0\'
# Mall为 RN 工程名字
workspace \'Mall.xcworkspace\'

target \'Mall\' do
  pod \'yoga\', :path => \'../node_modules/react-native/ReactCommon/yoga\'
  pod \'React\', :path => \'../node_modules/react-native\'
  pod \'SDWebImage\', \'4.0.0\'
  pod \'Toast\', \'~> 3.1.0\'
  pod \'M80AttributedLabel\', \'~> 1.6.3\'
  pod \'TZImagePickerController\', \'~> 1.9.0\'
  pod \'FMDB\', \'~> 2.7.2\'
  pod \'Reachability\', \'~> 3.2\'
  pod \'CocoaLumberjack\', \'~> 3.2.1\'
  pod \'SSZipArchive\', \'~> 1.8.1\'
  pod \'SVProgressHUD\', \'~> 2.0.3\'
  # 网易云信的 NIMKit 包
  pod \'NIMKit/Full\', \'~> 1.9.1\'
end

此处和源码里的podfile内容有点不一致，如果不太清楚各项配置的意思，按照我的配置来就行了。

3. 添加完成后在 terminal 窗口里（Podfile 目录中）执行 pod install，执行完成后会在 ios 目录下生成对应的 Mall.xcworkspace 文件，以后使用Xcode打开项目就是双击此文件即可。

3. 拷贝IM源码到RN里

• 将demo中的 NIMDemo 目录下的 Classes 和 Supporting Files 拷贝到项目的 ios/Mall 目录下 （与Images.xcassets文件夹同级）

 

拷贝文件

• 将 Supporting Files 目录下的 Info.plist nim_debug.xcconfig nim_release.xcconfig和 main.m 文件删除

• 将 NTESAppDelegate.m 内容和自己工程中的 AppDelegate.m 文件中的代码进行合并，并修改和去掉部分不需要的代码。

如下代码是我的AppDelegate.m文件的内容
