前言
很多app種都集成環(huán)信做第三方信息通訊工具，這里我們就看一下環(huán)信的主要功能和集成方法窑邦。先給出環(huán)信3.0的地址爷速。

這一篇主要說(shuō)一下環(huán)信的 基于環(huán)信3.0的及時(shí)通訊在具體工程上的應(yīng)用
一、環(huán)信的集成
工程里我使用的是pod進(jìn)行集成的持搜，環(huán)信有兩個(gè)版本吉殃，一個(gè)版本是帶語(yǔ)音功能的辞居，另外一個(gè)版本是不帶語(yǔ)音功能的，我集成的是帶語(yǔ)音功能的蛋勺，方便以后項(xiàng)目需求有所擴(kuò)展瓦灶，目前的項(xiàng)目還是用不到語(yǔ)音的。
pod 'Hyphenate'
下面看一下集成后的環(huán)信文檔組織結(jié)構(gòu)抱完。
代碼組織結(jié)構(gòu)-1
代碼組織架構(gòu)-2
二贼陶、環(huán)信的使用
下面就以具體工程為例進(jìn)行具體說(shuō)一下環(huán)信的集成。
單例類管理環(huán)信狀態(tài)
下面新建立一個(gè)環(huán)信單例類乾蛤，在這個(gè)類里的方法主要就是管理登錄狀態(tài)每界，以及幾個(gè)代理的回調(diào)捅僵，包括是否登錄的代理回調(diào)家卖、是否收到消息的代理回調(diào)以及消息是否送達(dá)和讀取的回調(diào)等。
下面看代碼庙楚。
//這個(gè)頭文件繼承自NSObject
#import "JJBaseModel.h"
@interface JJMessageDataTool : NSObject <EMClientDelegate, EMChatManagerDelegate>
//單例
+ (instancetype)shareMessageTool;
//登錄
- (void) loginEMClient;
//退出登陸
- (void) layoutEMClient;
//獲取登陸狀態(tài)
- (BOOL) getLoginStatus;
@end
這里的頭文件上荡，沒(méi)有暴露出是否讀取和有消息的回調(diào)接口，后面會(huì)加上該接口。
#import "JJMessageDataTool.h"
@interface JJMessageDataTool () <EMClientDelegate, EMChatManagerDelegate>
@property (nonatomic, strong) EMClient *client;
@end
@implementation JJMessageDataTool
#pragma mark - Class Public Function

{

static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
tool = [[JJMessageDataTool alloc] init];
EMOptions *options = [EMOptions optionsWithAppkey:@"你的環(huán)信appKey"];
[[EMClient sharedClient] initializeSDKWithOptions:options];
[[EMClient sharedClient] addDelegate:tool delegateQueue:nil]; //回調(diào)代理
[[EMClient sharedClient].chatManager addDelegate:tool delegateQueue:nil];
});
return tool;
}
//自動(dòng)登錄回調(diào)
- (void)connectionStateDidChange:(EMConnectionState)aConnectionState
{
if (aConnectionState == EMConnectionConnected) {
NSLog(@"環(huán)信已連接");
}
else {
NSLog(@" 環(huán)信連接斷開(kāi)");
}
}
//會(huì)話列表發(fā)生變化
- (void)conversationListDidUpdate:(NSArray *)aConversationList
{
[[NSNotificationCenter defaultCenter] postNotificationName:kJJPrivateMessageListChat object:aConversationList];
}
//收到消息
- (void)messagesDidReceive:(NSArray *)aMessages
{
[[NSNotificationCenter defaultCenter] postNotificationName:kJJPrivateMessageChat object:aMessages];
}
//消息已讀
- (void)messagesDidRead:(NSArray *)aMessages
{
}
//消息已送達(dá)
- (void)messagesDidDeliver:(NSArray *)aMessages
{
}
//登錄
- (void) loginEMClient
{
dispatch_async(dispatch_get_global_queue(0, 0), ^{
if ([JJConfig getOwnID]) {
//登錄
EMError *loginError = [[EMClient sharedClient] loginWithUsername:[JJConfig getOwnID] password:[JJConfig getEasePassword]];
if (!loginError) {
[[EMClient sharedClient].options setIsAutoLogin:YES];
NSLog(@"環(huán)信登錄成功!!!");
}
else {
NSLog(@"環(huán)信登錄失敗,失敗原因是%@",loginError.errorDescription);
}
}
});
}
//退出登陸
- (void) layoutEMClient
{
dispatch_async(dispatch_get_global_queue(0, 0), ^{
[[EMClient sharedClient] logout:YES completion:^(EMError *aError) {
NSLog(@"環(huán)信已退出登陸");
}];
});
}
//獲取登陸狀態(tài)
- (BOOL) getLoginStatus
{
if ([EMClient sharedClient].currentUsername && [EMClient sharedClient].currentUsername.length > 0) {
return YES;
}
return NO;
}
@end
這個(gè)是個(gè)工具在appDidFinishLaunching的時(shí)候就要初始化酪捡，與app生命周期相同叁征，全局進(jìn)行監(jiān)控和管理。
服務(wù)端和客戶端的分工
我們這里繼承環(huán)信需要服務(wù)端的參與逛薇，但是參與的不是很多捺疼，主要如下：
- 服務(wù)端負(fù)責(zé)返回給我們環(huán)信的密碼，注冊(cè)是在服務(wù)端做的永罚；
- 客戶端進(jìn)行其他方面的UI以及邏輯控制啤呼。
我們客戶端向自己的服務(wù)器請(qǐng)求，獲取環(huán)信的密碼呢袱。
這里客戶端有幾點(diǎn)要主要注意：
- 我們這邊是登錄的時(shí)候官扣，服務(wù)器會(huì)返回給我們環(huán)信密碼，而我們登錄分為三方以及手機(jī)號(hào)登錄羞福，因此惕蹄，要在這兩個(gè)地方保存返回的環(huán)信密碼，保存在沙盒治专。
userInfo.easePasswordStr = [dataDict objectForKey:@"easemobPassword"];
//環(huán)信登錄卖陵，在本app登錄成功后登錄環(huán)信
[[ZBMessageDataTool shareMessageTool] loginEMClient];
將這個(gè)字典在兩處登錄成功以后保存，然后以字典的形式保存在偏好設(shè)置里面看靠。
但是app在啟動(dòng)方法里面- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions也要判斷登錄狀態(tài)赶促，如果沒(méi)有登錄，要進(jìn)行登錄挟炬，同樣是用上面的單例進(jìn)行登錄管理工作鸥滨。
1. AppDelegate.m
if ([[JMessageDataTool shareMessageTool] getLoginStatus]) {
//已自動(dòng)登錄
NSLog(@"環(huán)信自動(dòng)登錄");
}
else {
[[JJMessageDataTool shareMessageTool] loginEMClient];
}
登錄好了，下面就是客戶端的工作了谤祖。
客戶端的實(shí)現(xiàn)
下面就是我們的重頭戲婿滓，那就是客戶端的實(shí)現(xiàn)了，前面登錄邏輯以及其他的集成管理都做好了粥喜，下面就是客戶端的事了凸主。我們點(diǎn)擊用戶頭像，然后在點(diǎn)擊發(fā)消息的按鈕额湘，就可以發(fā)送消息了卿吐。
下面先準(zhǔn)備下數(shù)據(jù)。
- (void)contactChatButtonDidClick:(JJUIButton *)button
{
NSLog(@"發(fā)送消息的按鈕被點(diǎn)擊了");
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];
}
這里JJChatViewController是聊天室锋华，JJMessageModel這個(gè)是聊天數(shù)據(jù)模型嗡官。下面看一下數(shù)據(jù)模型。
#import <Foundation/Foundation.h>
#import "JJMessageChatModel.h"
//私信模型
@interface JJMessageModel : JJBaseModel
@property (nonatomic, copy) NSString *lastMessage; //最后一條消息
@property (nonatomic, copy) NSString *uname; //發(fā)送者昵稱
@property (nonatomic, copy) NSString *uhead; //發(fā)送者頭像

這里還有幾個(gè)類需要說(shuō)明一下婆咸。
首先要說(shuō)的是JJMessageChatModel這個(gè)類竹捉，這個(gè)類的作用就是存放聊天室每個(gè)cell里面的數(shù)據(jù)模型。
#import <Foundation/Foundation.h>
#import "JJLiveModel.h"
#import "JJShortVideoModel.h"
typedef NS_ENUM(NSInteger ,MessageDirection)
{
MessageDirectionSend = 1, //發(fā)送消息
MessageDirectionReceive //接受消息
};
//聊天模型

下面還有個(gè)類就是JJChatModelFrame块差，這個(gè)類的作用就是負(fù)責(zé)給每一個(gè)cell賦值并調(diào)整每一個(gè)cell的大小，如下所示：
