关于融云SDK的使用(IMKit)

1.注册申请APPKEY不多说了

2.AppDelegate相关设置

// 初始化融云SDK
[[RCIM sharedRCIM]initWithAppKey:@"你的APPKEY"];

3.与融云交互的相关代理设置

    //用户信息提供者
    [[RCIM sharedRCIM] setUserInfoDataSource:self];
    //群组信息提供者
    [[RCIM sharedRCIM] setGroupInfoDataSource:self];
    //群名片信息提供者
    [[RCIM sharedRCIM] setGroupUserInfoDataSource:self];
    //IMKit连接状态的监听器
    [[RCIM sharedRCIM] setConnectionStatusDelegate:self];
    //IMKit消息接收的监听器
    [[RCIM sharedRCIM] setReceiveMessageDelegate:self];
    //是否关闭本地通知，默认是打开的
    [[RCIM sharedRCIM] setDisableMessageNotificaiton:NO];

4.实现设置好的代理

/**
 *  用户信息提供者
 *
 *  @param userId     <#userId description#>
 *  @param completion <#completion description#>
 */
- (void)getUserInfoWithUserId:(NSString *)userId completion:(void (^)(RCUserInfo *))completion
{
        //通过代理方法获得的userid去获取详细信息（）
        RCUserInfo *user = [[RCUserInfo alloc]init];
        user.userId = [@"用户id"];
        user.name = [@"用户昵称"];
        user.portraitUri = [@"头像"];
        return completion(user);
}

/**
 *  群组信息提供者
 *
 *  @param groupId    <#groupId description#>
 *  @param completion <#completion description#>
 */
-(void)getGroupInfoWithGroupId:(NSString *)groupId completion:(void (^)(RCGroup *))completion
{
        //通过代理方法获得的groupId去获取详细信息（）  
        RCGroup * group  = [[RCGroup alloc]init];
        group.groupName = [群组昵称];
        group.groupId = [群组id];
        group.portraitUri = [头像];
        return completion(group);
  
}

/**
 *  网络状态变化。
 *
 *  @param status 网络状态。
 */
- (void)onRCIMConnectionStatusChanged:(RCConnectionStatus)status {
    if (status == ConnectionStatus_KICKED_OFFLINE_BY_OTHER_CLIENT) {
        UIAlertView *alert = [[UIAlertView alloc]
                              initWithTitle:@"提示"

                              delegate:nil
                              cancelButtonTitle:@"知道了"
                              otherButtonTitles:nil, nil];
        MS_LoginFirstViewController *loginfirst = [[MS_LoginFirstViewController alloc] init];

        window.rootViewController = nav;
   
        [alert show];
      
    } else if (status == ConnectionStatus_TOKEN_INCORRECT) {
        dispatch_async(dispatch_get_main_queue(), ^{
          
            UIAlertView *alertView =
            [[UIAlertView alloc] initWithTitle:nil
                                       message:@"已过期，请重新登录"
                                      delegate:nil
                             cancelButtonTitle:@"确定"

            window.rootViewController = nav;
            
            [alertView show];
        });
    }
}

/*!
 接收消息的回调方法
 
 @param message     当前接收到的消息
 @param left        还剩余的未接收的消息数，left>=0
 
 @discussion 如果您设置了IMKit消息监听之后，SDK在接收到消息时候会执行此方法（无论App处于前台或者后台）。
 其中，left为还剩余的、还未接收的消息数量。比如刚上线一口气收到多条消息时，通过此方法，您可以获取到每条消息，left会依次递减直到0。
 您可以根据left数量来优化您的App体验和性能，比如收到大量消息时等待left为0再刷新UI。
