步驟如下：

1浮禾、下載SDKhttp://www.easemob.com/download
證書下載上傳
后期發(fā)送消息 需要推送發(fā)送的內(nèi)容
http://docs.easemob.com/doku.php?id=im:300iosclientintegration:10prepareforsdkimport

1下載SDK.png

2交胚、導(dǎo)入下載好的SDK

2.導(dǎo)入下載好的SDK.png

3、添加依賴庫

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 -> 雙擊other linker flags后邊添加-force_load -> 將libHyphenateSDK.a拖到-force_load下邊（出現(xiàn)10個警告）如果拖libHyphenateFullSDK.a文件 會出現(xiàn)4個錯誤
注意：SDK不支持bitcode,向Build Settings → Linking(搜bit) → Enable Bitcode中設(shè)置NO盈电。

7互拾、導(dǎo)入靜態(tài)庫 運(yùn)行后會有很多報錯

8、添加PCH到工程

10颜矿、注冊環(huán)信

11、實現(xiàn)單聊功能

注冊環(huán)信

1）導(dǎo)入頭文件#import "EMSDK.h"
（2）注冊代碼
EMOptions *options = [EMOptions optionsWithAppkey:@"xuanyi#im"];
options.apnsCertName = @"DDD";
[[EMClient sharedClient] initializeSDKWithOptions:options];
（3）用戶注冊
EMError *error = [[EMClient sharedClient] registerWithUsername:@"ming" password:@"111"];
（4）用戶登錄
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》遭拒絕didReceiveDeclinedFromUsername:

注意：
如果項目中使用-ObjC有沖突,可以添加-force_load來解決嫉晶， 添加-force_load：
targets->build setting->other linker flags->添加-force_load->靜態(tài)庫拖動到他的下面骑疆，-force_load[空格]EaseMobSDK/lib/libHyphenateSDK.a(靜態(tài)庫的路徑)。

代碼：

• (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
  //AppKey:注冊的appKey替废，詳細(xì)見下面注釋箍铭。
  //apnsCertName:推送證書名(不需要加后綴)，詳細(xì)見下面注釋椎镣。
  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進(jìn)入后臺

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

// App將要從后臺返回

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