用Quickblox接收離線消息

Question

用戶上線時沒有收到離線消息。

您能否解釋爲什麼用戶不會收到離線消息？

Answer 1

我用下面的查詢來獲取以前的消息。

let resPage = QBResponsePage(limit:100, skip:self.messageHandler.messageArray.count) 
let parameters = ["sort_desc" : "date_sent"] 
QBRequest.messagesWithDialogID(createdDialog.ID, 
           extendedRequest: parameters, 
           forPage: resPage, 
           successBlock: 
           {(response: QBResponse, messages: [QBChatMessage]?, responcePage: QBResponsePage?) in 
           /*** You will get all the previous messages ***/ 
           }, 
           errorBlock: {(response: QBResponse!) in 
           /*** Some error occured while getting messages ***/ 
           })
