我正在开发一个聊天应用程序,我需要显示消息状态,如WhatsApp应用程序,我已经尝试过XEP-0333(聊天标记),但面临问题。
1)从其他端获取Received Marker后,XMPPMessage Archive未更新消息,带有Received Marker(在Core数据中,消息聊天标记状态未更新)。
2)如何实现显示的标记逻辑? (表示我们需要发送显示标记的每条消息或一次只能显示一个对话框。)
XEP链接:XEP-0333
代码:
//(Sender Part)
let completeMessage = DDXMLElement.element(withName: "message") as! DDXMLElement //(In that i have set id,body,to and type as chat)
let msgObj = XMPPMessage(from: completeMessage)
msgObj?.addMarkableChatMarker()
xmppStream?.send(msgObj)
//(Receiver Part)
didReceivedMessage - Method
//*Check One condition*
if message.isChatMessageWithBody() && message.isErrorMessage() == false {
if (message.hasChatMarker() == true){
printLog("Message ID\(message.elementID())")
let msgElement = XMPPMessageMng.getChatMessageElement(recipient: message.from().bare(), thread: "")
let threadElement = DDXMLElement.element(withName: "thread") as! DDXMLElement
threadElement.stringValue = "Thread"
msgElement.addChild(threadElement)
let msgReceived = XMPPMessage(from: msgElement)
msgReceived?.addReceivedChatMarker(withID: message.elementID())
xmppStream.send(msgReceived)
}
}
else{
if (message.hasMarkableChatMarker() == true){
printLog("Chat Marker ID\(message.chatMarkerID())")
}else if (message.hasReceivedChatMarker() == true){
printLog("Chat Marker ID\(message.chatMarkerID())")
}
}
//对于展示标记我已做过以下事情。 - 使用JID从消息存档加载消息时。 loadArchivedMessagesFromJID - 方法
//message as XMPPMessageArchiving_Message_CoreDataObject
let msgReceived = XMPPMessage(from: msgElement)
msgReceived?.addDisplayedChatMarker(withID: message.message.elementID())
xmppStream.send(msgReceived)
让我知道我们可以通过哪种方式实现聊天标记协议。
