环信透传

1、        发透传消息

//通过透传发送当前位置信息给领导         EMChatCommand *shareCommand = [[EMChatCommand alloc] init];         shareCommand.cmd = @"ResponseLocation";            // 当前cmd消息的关键字         EMCommandMessageBody *shareMsgBody = [[EMCommandMessageBody alloc] initWithChatObject:shareCommand];         //设置要发给谁, fromToken是环信用户username或者群聊groupid         EMMessage *shareMsg = [[EMMessage alloc] initWithReceiver:_fromToken bodies:@[shareMsgBody]];         shareMsg.messageType = eMessageTypeChat;   // 单聊或者群聊         //latitude,longitude:获取到的经纬度         shareMsg.ext = @{                          @"latitude":[NSString stringWithFormat:@"%f",lat],                          @"longitude":[NSString stringWithFormat:@"%f",lng],                          @"reporttime":_reporttime,                          @"track":@""                         };         [[EaseMob sharedInstance].chatManager asyncSendMessage:shareMsg progress:nil];

 

2、        接收透传消息

-(void)didReceiveCmdMessage:(EMMessage *)cmdMessage{     EMCommandMessageBody *body = cmdMessage.messageBodies.firstObject;     //接收员工的即时位置信息     if ([body.action isEqualToString:@"ResponseLocation"]) {         NSString *latitude = [cmdMessage.ext objectForKey:@"latitude"];         NSString *longitude = [cmdMessage.ext objectForKey:@"longitude"];         NSString *reporttime = [cmdMessage.ext objectForKey:@"reporttime"];                 NSMutableDictionary *locationInfo = [[NSMutableDictionary alloc] init];         [locationInfo setObject:latitude forKey:@"lat"];         [locationInfo setObject:longitude forKey:@"lng"];         [locationInfo setObject:reporttime forKey:@"reporttime"];                 [[NSNotificationCenter defaultCenter] postNotificationName:@"userLocationNotification" object:nil userInfo:locationInfo];     } }

 

3、        配置

若想APP在后台时也使用，要在环信后台配置ios证书
