Quickblox聊天室中有多少条消息？

Question

我知道我会在房间历史记录中收到最后50条消息。但是，如果聊天室历史记录的消息少于50条，我将如何知道会收到多少条消息？

Answer 1

加入房间后

[[QBChat instance] joinRoom:testRoom];

您将收到委托中的所有邮件，并以此方式计算

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提供单独的请求以获取特定对话框的大量聊天消息：
类似于javascript：

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

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