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
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
appkey:(NSString *)appkey
apnsCertName:(NSString *)apnsCertName
otherConfig:(NSDictionary *)otherConfig
{
//注册登录状态监听
// [[NSNotificationCenter defaultCenter] addObserver:self
// selector:@selector(loginStateChange:)
// name:KNOTIFICATION_LOGINCHANGE
// object:nil]; //注册AppDelegate默认回调监听
[self _setupAppDelegateNotifications]; //注册apns
[self _registerRemoteNotification]; //注册easemob sdk
[[EaseMob sharedInstance] registerSDKWithAppKey:appkey
apnsCertName:apnsCertName
otherConfig:otherConfig];
// 注册环信监听
[self registerEaseMobLiteNotification]; //启动easemob sdk
[[EaseMob sharedInstance] application:application didFinishLaunchingWithOptions:launchOptions];
[[EaseMob sharedInstance].chatManager setIsAutoFetchBuddyList:YES];
} #pragma mark - EMChatManagerLoginDelegate 自动登录代理回调 // 自动登录开始回调
-(void)willAutoLoginWithInfo:(NSDictionary *)loginInfo error:(EMError *)error
{
// UIAlertView *alertView = nil;

}
else{

EMError *error = [[EaseMob sharedInstance].chatManager importDataToNewDatabase];
if (!error) {
[[EaseMob sharedInstance].chatManager loadDataFromDatabase]; //获取数据
[self loadConversations];
}
}
// [alertView show];
} // 自动登录结束回调
-(void)didAutoLoginWithInfo:(NSDictionary *)loginInfo error:(EMError *)error
{

}

} // [alertView show];
} #pragma make - login easemob 用户登录 - (void)loginWithUsername:(NSString *)username
password:(NSString *)password
{
[[EaseMob sharedInstance].chatManager asyncLoginWithUsername:username password:password completion:^(NSDictionary *loginInfo, EMError *error) {
if (!error) {
//设置自动登录
[[EaseMob sharedInstance].chatManager setIsAutoLoginEnabled:YES]; //获取数据
[self loadConversations]; //发送自动登陆状态通知
[[NSNotificationCenter defaultCenter] postNotificationName:KNOTIFICATION_LOGINCHANGE object:@YES];
}
} onQueue:nil];
} #pragma mark - load conversations 加载会话列表
-(void)loadConversations{ // [[EaseMob sharedInstance].chatManager importDataToNewDatabase]; //获取数据库中数据

if (conversations.count == ) {
//从数据库conversation表获取
conversations = [[EaseMob sharedInstance].chatManager loadAllConversationsFromDatabaseWithAppend2Chat:YES];
}
_conversations = conversations;
}
在会话列表控制器中：
@interface KJAnswerQuestionController ()<UITableViewDataSource,UITableViewDelegate>
/** 所有会话 */
@property (strong,nonatomic)NSArray *arrConversations;
/** 提示视图 */
@property (strong,nonatomic)UIView *showingView;

chatVC.title = conversation.chatter;
chatVC.conversation = conversation;
chatVC.conversation.enableUnreadMessagesCountEvent = YES;
[self.navigationController pushViewController:chatVC animated:YES];
}
@end
在聊天控制器中，直接集成ChatViewController
#import "ChatViewController.h"

@end
@implementation KJChatViewController
- (void)viewDidLoad {

[self.conversation markAllMessagesAsRead:YES];
}
@end在自定义的会话列表cell中，显示会话联系人、最后一条记录、时间

-(void)setConversation:(EMConversation *)conversation{
_conversation = conversation; //设置头像
self.iconView.image = [UIImage imageNamed:@"head"]; //设置姓名
self.MainTextLabel.text = conversation.chatter; //设置提示数字
[self.badgeBtn setBadgeValue:[NSString stringWithFormat:@"%ld",conversation.unreadMessagesCount]]; //设置历史消息
self.subTextLabel.text = [self latestMessageTitleForConversation:conversation]; //设置历史消息时间

} #pragma mark - 最后一条消息展示内容
-(NSString *)latestMessageTitleForConversation:(EMConversation *)conversation

default: {
} break;
}
}
return latestMessageTitle;
} #pragma mark - 最后一条消息展示时间
- (NSString *)latestMessageTimeForConversation:(EMConversation *)conversation
{
//用户获取最后一条message,根据lastMessage中timestamp,自定义时间文案显示(例如:"1分钟前","14:20")
NSString *latestMessageTime = @"";
EMMessage *lastMessage = [conversation latestMessage];;
if (lastMessage) {
latestMessageTime = [NSDate formattedTimeFromTimeInterval:lastMessage.timestamp];
}
return latestMessageTime;
}
@end
消息提醒按钮
#import <UIKit/UIKit.h> @interface KJBadgeButton : UIButton
@property (nonatomic, copy) NSString *badgeValue;
@end #import "KJBadgeButton.h" @implementation KJBadgeButton - (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {

self.titleLabel.font = [UIFont systemFontOfSize:];
}
return self;
} - (void)setBadgeValue:(NSString *)badgeValue
{

// _badgeValue = badgeValue;
_badgeValue = [badgeValue copy]; if (badgeValue && [badgeValue intValue] != ) {

badgeW = badgeSize.width + ;
}
frame.size.width = badgeW;
frame.size.height = badgeH;
self.frame = frame;
} else {
self.hidden = YES;
}
} @end
最后在TabbarController中检测未读消息
//首先得注册代理,监听未读消息数
[[EaseMob sharedInstance].chatManager addDelegate:self delegateQueue:nil];
#pragma mark - EMChatManagerChatDelegate
/**
* 历史会话列表更新了会调用
*/
- (void)didUpdateConversationList:(NSArray *)conversationList
{
// 给数据源重新赋值
self.arrConversations = conversationList; //刷新表格
[self.messageVc.tableView reloadData]; // 显示总的未读数
[self showTabBarBadge];
} /**
* 未读消息数改变了会调用
*/
- (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

演示结果如下：经本人测试，在真机上运行没有问题，实时语音视频聊天均能够实现
左边为电话通话 右边为视频通话
