环信集成步骤

步骤如下：

1、下载SDKhttp://www.easemob.com/download
证书下载上传
后期发送消息 需要推送发送的内容
http://docs.easemob.com/doku.php?id=im:300iosclientintegration:10prepareforsdkimport

1下载SDK.png

2、导入下载好的SDK

3、添加依赖库

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

添加-force_load
target -> build settings -> 搜索other linker flags -> 双击other linker flags后边添加-force_load -> 将libHyphenateSDK.a拖到-force_load下边（出现10个警告）如果拖libHyphenateFullSDK.a文件 会出现4个错误
注意：SDK不支持bitcode,向Build Settings → Linking(搜bit) → Enable Bitcode中设置NO。

11、实现单聊功能

注册环信

1）导入头文件#import "EMSDK.h"
（2）注册代码
EMOptions *options = [EMOptions optionsWithAppkey:@"xuanyi#im"];
options.apnsCertName = @"DDD";
[[EMClient sharedClient] initializeSDKWithOptions:options];
（3）用户注册
EMError *error = [[EMClient sharedClient] registerWithUsername:@"ming" password:@"111"];
（4）用户登录
EMError *error = [[EMClient sharedClient] loginWithUsername:@"ming" password:@"111"];
（5）添加好友
《1》EMError *error = [[EMClient sharedClient].contactManager addContact:@"xiao" message:@"..."];
《2》[[EMClient sharedClient].contactManager addDelegate:self delegateQueue:nil];
《3》成功didReceiveAgreedFromUsername:
《4》遭拒绝didReceiveDeclinedFromUsername:

注意：
如果项目中使用-ObjC有冲突,可以添加-force_load来解决， 添加-force_load：
targets->build setting->other linker flags->添加-force_load->静态库拖动到他的下面，-force_load[空格]EaseMobSDK/lib/libHyphenateSDK.a(静态库的路径)。

代码：

• (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
  //AppKey:注册的appKey，详细见下面注释。
  //apnsCertName:推送证书名(不需要加后缀)，详细见下面注释。
  EMOptions *options = [EMOptions optionsWithAppkey:@"chen0828#childrenstory"];
  options.apnsCertName = @"not";
  [[EMClient sharedClient] initializeSDKWithOptions:options];

  [[EaseSDKHelper shareHelper] easemobApplication:application
  didFinishLaunchingWithOptions:launchOptions
  appkey:@"chen0828#childrenstory"
  apnsCertName:@"not"
  otherConfig:@{kSDKConfigEnableConsoleLogger:[NSNumber numberWithBool:YES]}];
  return YES;
  }
  // App进入后台

• (void)applicationDidEnterBackground:(UIApplication *)application
  {
  [[EMClient sharedClient] applicationDidEnterBackground:application];
  }

// App将要从后台返回

• (void)applicationWillEnterForeground:(UIApplication *)application
  {
  [[EMClient sharedClient] applicationWillEnterForeground:application];
  }
