XMPPFramework - Retrieve Archived Messages From Openfire Server

Question

I am developing a chat app for iPhone using XMPP and openfire server,OpenFire server is storing all the chat history between users but When I try to retrieve the chat histor

Answer 1

an example to get archived messages in Swift 4

declares and initializes the variables XMPPMessageArchivingCoreDataStorage where I initialize the XMPPStream

var xmppMessageStorage: XMPPMessageArchivingCoreDataStorage?
var xmppMessageArchiving: XMPPMessageArchiving?

xmppMessageStorage = XMPPMessageArchivingCoreDataStorage.sharedInstance()
    xmppMessageArchiving = XMPPMessageArchiving(messageArchivingStorage: xmppMessageStorage)

    xmppMessageArchiving?.clientSideMessageArchivingOnly = true
    xmppMessageArchiving?.activate(stream)
    xmppMessageArchiving?.addDelegate(self, delegateQueue: DispatchQueue.main)

doing this, whenever a message arrives, this will cause it to be archived without needing to do anything else.

then, to retrieve the archived message

func RecibedMessageArchiving(idFriend: String) {

        let JabberIDFriend = idFriend   //id friend chat, example test1@example.com


        let moc = xmppMessageStorage?.mainThreadManagedObjectContext
        let entityDescription = NSEntityDescription.entity(forEntityName: "XMPPMessageArchiving_Message_CoreDataObject", in: moc!)
        let request = NSFetchRequest()
        let predicateFormat = "bareJidStr like %@ "
        let predicate = NSPredicate(format: predicateFormat, JabberIDFriend)

        request.predicate = predicate
        request.entity = entityDescription

        //jabberID id del usuario, cliente
        var jabberIDCliente = ""
        if let jabberj = globalChat.value(forKey: "jabberID"){
            jabberIDCliente = jabberj as! String
        }


        do {
            let results = try moc?.fetch(request)

            for message: XMPPMessageArchiving_Message_CoreDataObject? in results as? [XMPPMessageArchiving_Message_CoreDataObject?] ?? [] {

                var element: DDXMLElement!
                do {
                    element = try DDXMLElement(xmlString: (message as AnyObject).messageStr)
                } catch _ {
                    element = nil
                }

                let body: String
                let sender: String
                let date: NSDate
                let isIncomings: Bool
