iOS：集成環信EaseMobSDK單聊功能

當然在集成環信之前需要一些准備操作：

1、首先注冊環信開發者賬號,直接進入環信官網注冊即可：http://www.easemob.com

2、按照文檔一步一步將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中這個EaseSDKHelper單例類來注冊、登錄、獲取最新消息、推送等

在App啟動程序時：

進入EaseSDKHelper單例類中,添加一些自定義的方法

#pragma mark - init easemob  注冊環信

    }
    _conversations = conversations;
}

在會話列表控制器中：

@interface KJAnswerQuestionController ()<UITableViewDataSource,UITableViewDelegate>
/** 所有會話 */
@property (strong,nonatomic)NSArray *arrConversations;
/** 提示視圖 */
@property (strong,nonatomic)UIView *showingView;

在聊天控制器中，直接集成ChatViewController

最后在TabbarController中檢測未讀消息

 //首先得注冊代理,監聽未讀消息數
 [[EaseMob sharedInstance].chatManager addDelegate:self delegateQueue:nil];

#pragma mark - EMChatManagerChatDelegate
/**

 */
- (void)didUpdateConversationList:(NSArray *)conversationList
{
    // 給數據源重新賦值
    self.arrConversations = conversationList;
    
    //刷新表格
    [self.messageVc.tableView reloadData];
    
    // 顯示總的未讀數
    [self showTabBarBadge];
}

/**
 *  未讀消息數改變了會調用
 */
- (void)didUnreadMessagesCountChanged
{
    //刷新表格
    [self.messageVc.tableView reloadData];
    
    // 顯示總的未讀數
    [self showTabBarBadge];
}

/**
 *  將總的未讀消息數顯示到tabBar上
 */
- (void)showTabBarBadge
{
    NSInteger totalUnreadCount = 0;
    for (EMConversation *conversation in self.arrConversations) {
        
        //獲取所有的聯系人發來的未讀消息
        totalUnreadCount += [conversation unreadMessagesCount];
        
    }
    if (totalUnreadCount > 0) {
        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:0];
    }
}

//移除代理
-(void)dealloc{ [[EaseMob sharedInstance].chatManager removeDelegate:self]; }

測試后：

 

 

 

以上只是實現了單聊和群聊的功能，那么實時語音和視頻如何實現呢，下面這個就是干貨：

1.集成實時通話的前提是集成好單聊，並且使用的是libEaseMobClientSDK.a包，因為這個包 包含實時通話的功能
2.將demo3.0中的Call文件(實時通話的界面)以及Resources(通話界面的資源圖片)加到你自己的工程中
3.點擊實時通話或者視頻的按鈕，實際是發起的通知，在你工程中的主控制器中監聽這個通知，在通知的方法中實現發起實時通話的方法以及跳轉到通話界面
4.接收實時通話的回調是  - (void)callSessionStatusChanged:(EMCallSession *)callSession changeReason:(EMCallStatusChangedReason)reason error:(EMError *)error  
5.實時通話用的協議是：EMCallManagerDelegate    代理：[[EaseMob sharedInstance].callManager addDelegate:self delegateQueue:nil];
6.具體添加哪些方法看下上傳的ViewController文件，按照這個文件中的方法加到自己的主控制器中，demo中的實現在MainViewController.m類

代碼如下：

記得先導入call文件:這個是用來進行視頻和電話語音的類
