前言
很多app种都集成环信做第三方信息通讯工具，这里我们就看一下环信的主要功能和集成方法。先给出环信3.0的地址。

这一篇主要说一下环信的 基于环信3.0的及时通讯在具体工程上的应用
一、环信的集成
工程里我使用的是pod进行集成的，环信有两个版本，一个版本是带语音功能的，另外一个版本是不带语音功能的，我集成的是带语音功能的，方便以后项目需求有所扩展，目前的项目还是用不到语音的。
pod 'Hyphenate'
下面看一下集成后的环信文档组织结构。

代码组织架构-2
二、环信的使用
下面就以具体工程为例进行具体说一下环信的集成。
单例类管理环信状态
下面新建立一个环信单例类，在这个类里的方法主要就是管理登录状态，以及几个代理的回调，包括是否登录的代理回调、是否收到消息的代理回调以及消息是否送达和读取的回调等。
下面看代码。
//这个头文件继承自NSObject
#import "JJBaseModel.h"
@interface JJMessageDataTool : NSObject <EMClientDelegate, EMChatManagerDelegate>
//单例
+ (instancetype)shareMessageTool;
//登录
- (void) loginEMClient;
//退出登陆
- (void) layoutEMClient;
//获取登陆状态
- (BOOL) getLoginStatus;
@end
这里的头文件，没有暴露出是否读取和有消息的回调接口，后面会加上该接口。
#import "JJMessageDataTool.h"
@interface JJMessageDataTool () <EMClientDelegate, EMChatManagerDelegate>
@property (nonatomic, strong) EMClient *client;
@end
@implementation JJMessageDataTool
#pragma mark - Class Public Function
+ (instancetype)shareMessageTool
{
static JJMessageDataTool *tool = nil;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
tool = [[JJMessageDataTool alloc] init];
EMOptions *options = [EMOptions optionsWithAppkey:@"你的环信appKey"];
[[EMClient sharedClient] initializeSDKWithOptions:options];
[[EMClient sharedClient] addDelegate:tool delegateQueue:nil]; //回调代理
[[EMClient sharedClient].chatManager addDelegate:tool delegateQueue:nil];
});
return tool;
}
//自动登录回调
- (void)connectionStateDidChange:(EMConnectionState)aConnectionState
{
if (aConnectionState == EMConnectionConnected) {
NSLog(@"环信已连接");
}
else {
NSLog(@" 环信连接断开");
}
}
//会话列表发生变化
- (void)conversationListDidUpdate:(NSArray *)aConversationList
{
[[NSNotificationCenter defaultCenter] postNotificationName:kJJPrivateMessageListChat object:aConversationList];
}
//收到消息
- (void)messagesDidReceive:(NSArray *)aMessages
{
[[NSNotificationCenter defaultCenter] postNotificationName:kJJPrivateMessageChat object:aMessages];
}
//消息已读
- (void)messagesDidRead:(NSArray *)aMessages
{
}
//消息已送达
- (void)messagesDidDeliver:(NSArray *)aMessages
{
}
//登录
- (void) loginEMClient
{
dispatch_async(dispatch_get_global_queue(0, 0), ^{
if ([JJConfig getOwnID]) {
//登录
EMError *loginError = [[EMClient sharedClient] loginWithUsername:[JJConfig getOwnID] password:[JJConfig getEasePassword]];
if (!loginError) {
[[EMClient sharedClient].options setIsAutoLogin:YES];
NSLog(@"环信登录成功!!!");
}
else {
NSLog(@"环信登录失败,失败原因是%@",loginError.errorDescription);
}
}
});
}
//退出登陆
- (void) layoutEMClient
{
dispatch_async(dispatch_get_global_queue(0, 0), ^{
[[EMClient sharedClient] logout:YES completion:^(EMError *aError) {
NSLog(@"环信已退出登陆");
}];
});
}
//获取登陆状态
- (BOOL) getLoginStatus
{
if ([EMClient sharedClient].currentUsername && [EMClient sharedClient].currentUsername.length > 0) {
return YES;
}
return NO;
}
@end
这个是个工具在appDidFinishLaunching的时候就要初始化，与app生命周期相同，全局进行监控和管理。
服务端和客户端的分工
我们这里继承环信需要服务端的参与，但是参与的不是很多，主要如下：
- 服务端负责返回给我们环信的密码，注册是在服务端做的；
- 客户端进行其他方面的UI以及逻辑控制。
我们客户端向自己的服务器请求，获取环信的密码。
这里客户端有几点要主要注意：
- 我们这边是登录的时候，服务器会返回给我们环信密码，而我们登录分为三方以及手机号登录，因此，要在这两个地方保存返回的环信密码，保存在沙盒。
userInfo.easePasswordStr = [dataDict objectForKey:@"easemobPassword"];
//环信登录，在本app登录成功后登录环信
[[ZBMessageDataTool shareMessageTool] loginEMClient];
将这个字典在两处登录成功以后保存，然后以字典的形式保存在偏好设置里面。
但是app在启动方法里面- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions也要判断登录状态，如果没有登录，要进行登录，同样是用上面的单例进行登录管理工作。
1. AppDelegate.m
if ([[JMessageDataTool shareMessageTool] getLoginStatus]) {
//已自动登录
NSLog(@"环信自动登录");
}
else {
[[JJMessageDataTool shareMessageTool] loginEMClient];
}
登录好了，下面就是客户端的工作了。
客户端的实现
下面就是我们的重头戏，那就是客户端的实现了，前面登录逻辑以及其他的集成管理都做好了，下面就是客户端的事了。我们点击用户头像，然后在点击发消息的按钮，就可以发送消息了。
下面先准备下数据。
- (void)contactChatButtonDidClick:(JJUIButton *)button
{
NSLog(@"发送消息的按钮被点击了");
JJChatViewController *chatVC = [[JJChatViewController alloc] init];
JJMessageModel *messageModel = [[JJMessageModel alloc] init];
messageModel.toUserName = self.userModel.userNickname?:@"";
messageModel.uname = [JJConfig getOwnNicename]?:@"";
messageModel.uhead = [JJConfig myProfile].avatar?:@"";
messageModel.toUserHead = self.userModel.userAvatar?:@"";
chatVC.conversationId = [NSString stringWithFormat:@"%ld", self.userModel.userId];
chatVC.messageModel = messageModel;
chatVC.title = self.userModel.userNickname;
[self.navigationController pushViewController:chatVC animated:YES];
}
这里JJChatViewController是聊天室，JJMessageModel这个是聊天数据模型。下面看一下数据模型。
#import <Foundation/Foundation.h>
#import "JJMessageChatModel.h"
//私信模型
@interface JJMessageModel : JJBaseModel
@property (nonatomic, copy) NSString *lastMessage; //最后一条消息
@property (nonatomic, copy) NSString *uname; //发送者昵称
@property (nonatomic, copy) NSString *uhead; //发送者头像
@property (nonatomic, copy) NSString *toUserName; //接受者名称
@property (nonatomic, copy) NSString *toUserHead; //接受者头像
@property (nonatomic, copy) NSString *un_read_num; //未读数量
@property (nonatomic, copy) NSString *imgPath;
@property (nonatomic, copy) NSString *conversationId;
+ (instancetype)shareMessageModel;

下面我们看一下聊天室JJChatViewController。

这里还有几个类需要说明一下。
首先要说的是JJMessageChatModel这个类，这个类的作用就是存放聊天室每个cell里面的数据模型。
#import <Foundation/Foundation.h>
#import "JJLiveModel.h"
#import "JJShortVideoModel.h"
typedef NS_ENUM(NSInteger ,MessageDirection)
{
MessageDirectionSend = 1, //发送消息
MessageDirectionReceive //接受消息
};
//聊天模型
@interface JJMessageChatModel : JJBaseModel
@property (nonatomic, copy) NSString *avatar; //头像
@property (nonatomic, assign) MessageDirection messageDirection; //消息来源类型
@property (nonatomic, copy) NSString *messageId; //消息id;
@property (nonatomic, copy) NSString *messageContent; //文本消息；
@property (nonatomic, assign) long long timestamp; //消息时间戳
@property (nonatomic, copy) NSString *verify_info; //认证信息
@property (nonatomic, copy) NSString *cornerMark; //头像角标
@property (nonatomic, copy) NSString *message; //消息
@property (nonatomic, copy) NSString *remoteImageUrl; //图片网络地址
@property (nonatomic, copy) NSString *localImageUrl; //图片沙盒地址
@property (nonatomic, copy) UIImage *image; //图片
@property (nonatomic, assign) CGSize imaageSize;
@property (nonatomic, strong) JJShortVideoModel *videoModel;
@property (nonatomic, strong) JJLiveModel *liveModel;
@property (nonatomic, assign) int type;
@end
下面还有个类就是JJChatModelFrame，这个类的作用就是负责给每一个cell赋值并调整每一个cell的大小，如下所示：
1. JJChatModelFrame.h
#import <Foundation/Foundation.h>
#import "JJMessageViewController.h"
#import "JJMessageChatModel.h"
#define ChatHeadImage_height 42.0f
#define TimeLabel_height 20.0f
@interface JJChatModelFrame : NSObject
/** 时间的Frame */
@property (nonatomic,assign)CGRect timeLabelFrame;
/** 头像的Frame */
@property (nonatomic,assign)CGRect headImageFrame;
/** 聊天内容的Frame */
@property (nonatomic,assign)CGRect contentFrame;
/** 认证标志的Frame */
@property (nonatomic,assign)CGRect verifyBadgeFrame;
/** 消息来源类型 */
@property (nonatomic,assign) MessageDirection messageDirection;
/** 模型数据 */
@property (nonatomic,strong) JJMessageChatModel *messageModel;
/*cell的高度 */
@property (nonatomic,assign)CGFloat cellHeight;
@property (nonatomic, assign) int type; //1. 文字，2. 节目 3. 创意视频 4. 图片
/** 通过模型数据计算出对应的Frame,并且返回出modelFrame自己这个对象 */
- (instancetype)initWithFrameModel:model timestamp:(NSTimeInterval)timestamp;
//和上面同理
+ (instancetype)modelFrame:(JJMessageChatModel *)messageModel timestamp:(NSTimeInterval)timestamp;
@end
2. JJChatModelFrame.m

}

self.contentFrame = CGRectMake(kJJCommonScreenWidth-distance-ChatHeadImage_height-distance-width, CGRectGetMaxY(self.timeLabelFrame)+15, width, height);

}

if (cellH == NAN) {

}

}
return self;
}

还有一个界面需要说的就是，我们聊天室前一个界面，那就是消息列表页，这个页面主要就是记录系统消息，以及其他都谁给发过了消息，方便用户点击进入聊天室进行聊天。下面直接给出代码了。
