Quickblox聊天室中有多少条消息？

Question

我知道我会收到房间历史记录中的最后50封邮件。但是，如果聊天室历史记录少于50条消息，如何知道我将收到多少条消息？

Answer 1

后加入房间

[[QBChat instance] joinRoom:testRoom]; 

您将收到的所有邮件中的委托和计数这样

static int count = 0; 
- (void)chatRoomDidReceiveMessage:(QBChatMessage *)message fromRoom:(NSString *)roomName{ 
    NSLog(@"Did receive message: %@, from room %@", message, roomName); 
    ++count; 

    [NSObject cancelPreviousPerformRequestsWithTarget:self selector:@selector(receivedAllMessages) object:nil]; 
    [self performSelector:@selector(receivedAllMessages) withObject:nil afterDelay:1.0]; 
} 

- (void)receivedAllMessages{ 
    NSLog(@"%d", count); 
} 

Answer 2

Quickblox提供一个单独的请求得到了一些特定对话的聊天消息：
像in javascript：

var params = {chat_dialog_id: dialogId, count: 1}; 
QB.chat.message.list(params, function(err, messagesCount) { 
    if (messagesCount) { 

    }else{ 
    console.log(err); 
    } 
});
