当然在集成环信之前需要一些准备操作：

1、首先注册环信开发者账号,直接进入环信官网注册即可：http://www.easemob.com

2、按照文档一步一步将需要的文件全部拖入工程中：http://docs.easemob.com/start/start

以下是我集成的文件：使用

　　EaseUI集成：http://docs.easemob.com/start/300iosclientintegration/140easeuiuseguide

　　libEaseMobClientSDK.a包

　　ChatDemo-UI3.0中的ChatView中的聊天控制器

我主要使用EaseMob中这个EaseSDKHelper单例类来注册、登录、获取最新消息、推送等

在App启动程序时：

进入EaseSDKHelper单例类中,添加一些自定义的方法

#pragma mark - init easemob  注册环信

- (void)easemobApplication:(UIApplication *)application

最后在TabbarController中检测未读消息

    self.arrConversations = conversationList;

    //刷新表格

    [self.messageVc.tableView reloadData];

    // 显示总的未读数

    [self showTabBarBadge];

}

/**

 */

- (void)didUnreadMessagesCountChanged

{

    //刷新表格

    [self.messageVc.tableView reloadData];

    // 显示总的未读数

    [self showTabBarBadge];

}

/**

 *  将总的未读消息数显示到tabBar上

 */

- (void)showTabBarBadge

{

    NSInteger totalUnreadCount = ;

    for (EMConversation *conversation in self.arrConversations) {

        //获取所有的联系人发来的未读消息

        totalUnreadCount += [conversation unreadMessagesCount];

    }

    if (totalUnreadCount > ) {

        self.messageVc.tabBarItem.badgeValue = [NSString stringWithFormat:@"%ld",totalUnreadCount];

        UIApplication *application = [UIApplication sharedApplication];

        [application setApplicationIconBadgeNumber:totalUnreadCount];

    }else{

        self.messageVc.tabBarItem.badgeValue = nil;

        UIApplication *application = [UIApplication sharedApplication];

        [application setApplicationIconBadgeNumber:];

    }

}
//移除代理
-(void)dealloc{

    [[EaseMob sharedInstance].chatManager removeDelegate:self];

}

测试后：

 

以上只是实现了单聊和群聊的功能，那么实时语音和视频如何实现呢，下面这个就是干货：

1.集成实时通话的前提是集成好单聊，并且使用的是libEaseMobClientSDK.a包，因为这个包 包含实时通话的功能
2.将demo3.0中的Call文件(实时通话的界面)以及Resources(通话界面的资源图片)加到你自己的工程中
3.点击实时通话或者视频的按钮，实际是发起的通知，在你工程中的主控制器中监听这个通知，在通知的方法中实现发起实时通话的方法以及跳转到通话界面
4.接收实时通话的回调是  - (void)callSessionStatusChanged:(EMCallSession *)callSession changeReason:(EMCallStatusChangedReason)reason error:(EMError *)error  
5.实时通话用的协议是：EMCallManagerDelegate    代理：[[EaseMob sharedInstance].callManager addDelegate:self delegateQueue:nil];
6.具体添加哪些方法看下上传的ViewController文件，按照这个文件中的方法加到自己的主控制器中，demo中的实现在MainViewController.m类

代码如下：

记得先导入call文件:这个是用来进行视频和电话语音的类

ViewController.docx文件：http://i.cnblogs.com/Files.aspx
