 # ReactNative IMUI
 项目fork自 jpush 的 [Aurora IMUI](https://github.com/jpush/aurora-imui/tree/master/ReactNative)
 
-
 ## 使用
-当前提供的组件：
+参考[demo](https://github.com/reactnativecomponent/react-native-chat-demo)
+## 安装
+
+```
+npm install aurora-imui-react-native --save
+react-native link
+```
+
+如果 link 安卓失败，需要手动修改一下 `settings.gradle` 中的引用路径：
+
+```
+include ':app', ':aurora-imui-react-native'
+project(':aurora-imui-react-native').projectDir = new File(rootProject.projectDir, '../node_modules/aurora-imui-react-native/ReactNative/android')
+```
+
+然后在 app 的 `build.gradle`中引用：
+
+```
+dependencies {
+    compile project(':aurora-imui-react-native')
+}
+```
+
+**注意事项（Android）：我们使用了 support v4, v7 25.3.1 版本，因此需要将你的 build.gradle 中 buildToolsVersion 及 compiledSdkVersion 改为 25 以上。可以参考 sample 的配置。**
+
+## 配置
+
+- ### Android
+
+  - 引入 Package:
+
+  > MainApplication.java
+
+  ```
+  import cn.jiguang.imui.messagelist.ReactIMUIPackage;
+  ...
+
+  @Override
+  protected List<ReactPackage> getPackages() {
+      return Arrays.<ReactPackage>asList(
+          new MainReactPackage(),
+          new ReactIMUIPackage()
+      );
+  }
+  ```
+
+
+
+
+
+
+- ### iOS
+
+  - PROJECT -> TARGETS -> Build Settings -> Enable Bitcode Set to No
+  - Find PROJECT -> TARGETS -> General -> Embedded Binaries  and add RCTAuroraIMUI.framework
+  - 构建你的项目之前，你需要构建 RCTAuroraIMUI.framework
+
+## 数据格式
+
+使用 MessageList，你需要定义 `message` 对象和 `fromUser` 对象。
+
+- `message` 对象格式:
+
+**status 必须为以下四个值之一: "send_succeed", "send_failed", "send_going", "download_failed"，如果没有定义这个属性， 默认值是 "send_succeed".**
+
+ ```
+  message = {  // text message
+    msgId: "msgid",
+    status: "send_going",
+    msgType: "text",
+    isOutgoing: true,
+    text: "text"
+    fromUser: {}
+}
+
+message = {  // image message
+    msgId: "msgid",
+    msgType: "image",
+    isOutGoing: true,
+    progress: "progress string"
+    mediaPath: "image path"
+    fromUser: {}
+}
+
+
+message = {  // voice message
+    msgId: "msgid",
+    msgType: "voice",
+    isOutGoing: true,
+    duration: number, // 注意这个值有用户自己设置时长，单位秒
+    mediaPath: "voice path"
+    fromUser: {}
+}
+
+message = {  // video message
+    msgId: "msgid",
+    status: "send_failed",
+    msgType: "video",
+    isOutGoing: true,
+    druation: number
+    mediaPath: "voice path"
+    fromUser: {}
+}
+
+message = {  // event message
+    msgId: "msgid",
+    msgType: "event",
+    text: "the event text"
+}
+ ```
+
+-    `fromUser` 对象格式:
+
+  ```
+  fromUser = {
+    userId: ""
+    displayName: ""
+    avatarPath: "avatar image path"
+  }
+  ```
