一、准备工作

1、注册环信帐号

注册一个环信账号之后，我们用注册的帐号登陆。然后创建一个应用，会得到一个对应的AppKey,这个AppKey在初始化环信SDK的时候需要用到。

2、制作推送证书

如果需要做离线推送的功能，需要制作一个推送证书。如果只是需要实现单聊、群聊等功能，可以跳过此步骤。个人建议刚开始接触环信的开发者可以忽略此步骤。

3、下载环信SDK

点击下载环信iOS版的SDK

二、集成环信的SDK

1、把环信SDK添加到工程中

从环信官网下载下来的是一个压缩包，解压之后，把我们需要的环信SDK，即HyphenateSDK这个文件夹，整个的拖入到我们的工程中。如下图：

在lib文件夹下面有两个静态库，只需要用到一个，根据你的需求选择。

libHyphenateSDK.a不包含实时语音功能，libHyphenateFullSDK.a包含所有功能。

2、添加对应的依赖库

2.1. 向Build Phases → Link Binary With Libraries 中添加依赖库

SDK依赖库有

• CoreMedi.framework
• AudioToolbox.framework
• AVFoundation.framework
• MobileCoreServices.framework
• ImageIO.framework
• SystemConfiguration.framework
• libc++.dylib
• libresolv.dylib
• libz.dylib
• libstdc++.6.0.9.dylib
• libsqlite3.dylib

(如果使用的是xcode7，后缀为tbd)

SDK包含实时语音依赖库有

• CoreMedia.framework
• AudioToolbox.framework
• AVFoundation.framework
• MobileCoreServices.framework
• ImageIO.framework
• SystemConfiguration.framework
• libc++.dylib
• libresolv.dylib
• libz.dylib
• libstdc++.6.0.9.dylib
• libsqlite3.dylib
• libiconv.dylib

  

  温馨提示：注意不要添加错了，也不能添加少了，添加完毕之后，不要着急，先编译一下。编译成功，则说明没有问题；如果编译报错，则仔细对照上面例举的静态库进行添加，直到编译成功，再进行下一步。

  3、配置工程

  3.1 不包含语音静态库的配置方法

  (1) 删掉libHyphenateFullSDK.a，保留libHyphenateSDK.a；

  (2) 在Build Settings -> Other Linker Flags 添加”fore_load”和”libHyphenateSDK.a”的相对路径。

  如下图所示：

  

  3.2 包含语音静态库的配置方法

  (1) 删掉libHyphenateSDK.a，保留libHyphenateFullSDK.a；

  (2) 在Build Settings -> Other Linker Flags 添加”-ObjC”。

  如下图所示：

  

  4、验证SDK是否添加成功

  在AppDelegate.m文件中添加环信SDK初始化的方法，记得添加头文件”EaseMob.h”。下面提供了我用的测试AppKey，你可以替换成你自己申请的AppKey。编译成功，则说明你已经正确集成了环信的SDK了。

  如果编译有问题，可能存在的原因：

  (1) 静态库没有添加正确；

  (2) 静态库工程配置不正确；
