如何使用XMPP框架获取消息传递状态 [英] How to get the message delivary status using XMPP framework

问题描述

我正在使用XMPP框架在用户之间聊天，聊天正在发生。现在我需要显示消息是否完美地传递给两个设备，例如（What's app messenger）。我没有得到任何教程可以遵循。下面的代码表示我们向其他用户发送消息。

I am using the XMPP Framework for chatting between the users , Chatting is happening perfectly .Now I need to show the message is delivered perfectly to both devices like (What's app messenger). I am not getting any tutorial to follow. Below code represents while we send message to the other user.

//Sending the message to the other user
 NSXMLElement *body = [NSXMLElement elementWithName:@"body"];
 [body setStringValue:txtChat.text];

 NSXMLElement *message = [NSXMLElement elementWithName:@"message"];
 [message addAttributeWithName:@"type" stringValue:@"chat"];
 [message addAttributeWithName:@"to" stringValue:self.userjid];
 [message addChild:body];
 [[APPDELEGATE xmppStream] sendElement:message];

使用XMPP Framework重新获取消息时，我使用以下代码获取数据

While reterving the message by using XMPP Framework i was getting the data by using below code

- (void)loadarchivemsg
{        
    XMPPMessageArchivingCoreDataStorage *storage = [XMPPMessageArchivingCoreDataStorage sharedInstance];
    NSManagedObjectContext *moc = [storage mainThreadManagedObjectContext];
    NSEntityDescription *entityDescription = [NSEntityDescription entityForName:@"XMPPMessageArchiving_Message_CoreDataObject"
                                                         inManagedObjectContext:moc];
    NSFetchRequest *request = [[NSFetchRequest alloc]init];

    NSPredicate *predicate = [NSPredicate predicateWithFormat:@"(bareJidStr like %@) && (streamBareJidStr like %@)", self.userjid,[[NSUserDefaults standardUserDefaults] stringForKey:@"kXMPPmyJID"]];
    request.predicate = predicate;
    NSLog(@"%@",[[NSUserDefaults standardUserDefaults] stringForKey:@"kXMPPmyJID"]);
    [request setEntity:entityDescription];
    NSError *error;
    NSArray *messages_arc = [moc executeFetchRequest:request error:&error];

    [self print:[[NSMutableArray alloc]initWithArray:messages_arc]];    
}

- (void)print:(NSMutableArray*)messages_arc{
    @autoreleasepool {
        for (XMPPMessageArchiving_Message_CoreDataObject *message in messages_arc) {

            NSXMLElement *element = [[NSXMLElement alloc] initWithXMLString:message.messageStr error:nil];
            XMPPMessage *message12=[[XMPPMessage alloc]init];
            message12 = [message message];
  }
}

这就是为什么我发送消息并检索消息，你能帮我解决如何检索消息的传递状态。等待你的宝贵答案。

In this why I was sending the message and retrieving the message,can you help me how to retrieve the delivery status of the message . Waiting for your valuable answers.

推荐答案

@Romance你需要在connect方法中添加以下代码

@Romance you need to add below code in the connect method

  XMPPMessageDeliveryReceipts* xmppMessageDeliveryRecipts = [[XMPPMessageDeliveryReceipts alloc] initWithDispatchQueue:dispatch_get_main_queue()];
    xmppMessageDeliveryRecipts.autoSendMessageDeliveryReceipts = YES;
    xmppMessageDeliveryRecipts.autoSendMessageDeliveryRequests = YES;
    [xmppMessageDeliveryRecipts activate:self.xmppStream];

请记住在发送消息时添加这些行

Remember to add these line while sending message

NSString *messageID=[self.xmppStream generateUUID];

        NSXMLElement *message = [NSXMLElement elementWithName:@"message"];
        [message addAttributeWithName:@"id" stringValue:messageID];
        [message addAttributeWithName:@"type" stringValue:@"chat"];
        [message addAttributeWithName:@"to" stringValue:[NSString stringWithFormat:@"senderJabberID_Here"]];

        [message addChild:body];

希望这可以帮到你：）
