使用XMPPFramework为ios存储消息？ [英] Storing messages using XMPPFramework for ios?

问题描述

我不知道如何使用XMPPFramework的核心数据来存储传入的消息。有没有人有任何教程如何做到这一点？我看到User对象，这反过来可以有很多资源。收到的每条消息是否应该是我创建和保留的新资源？

我不知道什么部分是我的责任和框架提供的有关消息历史的部分。我可以拦截每个传入的消息。那么我应该使用核心数据在Messages表中创建和存储每条消息吗？
我有一个消息实体。每个XMPPUser都有一个Message对象数组。

谢谢！

解决方案

我知道这是一个老线程，但因为我目前使用XMPP在iOS上我必须说，有一个内置的支持XMPP中的邮件归档。

我下载了XMPP框架为iOS和在它有文件夹标记为XEP-0136。导入XCode中的文件夹，并通过使用以下代码类实例化XMPP客户端激活客户端存档：

  xmppMessageArchivingStorage = [XMPPMessageArchivingCoreDataStorage sharedInstance]; 
 xmppMessageArchivingModule = [[XMPPMessageArchiving alloc] initWithMessageArchivingStorage：xmppMessageArchivingStorage]; 
  

以下一行代码可以节省您将归档特定节发送到xmpp服务器
这将很可能响应与服务未实现

  [xmppMessageArchivingModule setClientSideMessageArchivingOnly：YES]; 
 
 [xmppMessageArchivingModule activate：xmppStream]; 
 [xmppMessageArchivingModule addDelegate：self delegateQueue：dispatch_get_main_queue（）]; 
  

您已设置。从那一刻起，消息（传出和传入）将被存储在框架创建的表中。

我是这样做的：

   - （void）testMessageArchiving {
 XMPPMessageArchivingCoreDataStorage * storage = [XMPPMessageArchivingCoreDataStorage sharedInstance]; 
 NSManagedObjectContext * moc = [storage mainThreadManagedObjectContext]; 
 NSEntityDescription * entityDescription = [NSEntityDescription entityForName：@XMPPMessageArchiving_Message_CoreDataObject
 inManagedObjectContext：moc]; 
 NSFetchRequest * request = [[NSFetchRequest alloc] init]; 
 [request setEntity：entityDescription]; 
 NSError *错误; 
 NSArray * messages = [moc executeFetchRequest：request error：& error]; 
 
 [self print：[[NSMutableArray alloc] initWithArray：messages]]; 
} 
 
  - （void）print：（NSMutableArray *）messages {
 @autoreleasepool {
 for（XMPPMessageArchiving_Message_CoreDataObject * message in messages）{
 NSLog （@messageStr param is％@，message.messageStr）; 
 NSXMLElement * element = [[NSXMLElement alloc] initWithXMLString：message.messageStr error：nil]; 
 NSLog（@to param is％@，[element attributeStringValueForName：@to]）; 
 NSLog（@NSCore object id param is％@，message.objectID）; 
 NSLog（@bareJid param is％@，message.bareJid）; 
 NSLog（@bareJidStr param is％@，message.bareJidStr）; 
 NSLog（@body param is％@，message.body）; 
 NSLog（@timestamp param is％@，message.timestamp）; 
 NSLog（@outgoing param is％d，[message.outgoing intValue]）; 
} 
} 
} 
  

希望它有帮助： / p>

I'm not sure how to use the XMPPFramework's core data to store incoming messages. Does anyone have any tutorials on how to do this? I see User objects, which in turn can have many "resources". Is each message received supposed to be a new resource that I create and persist?

I do not know what part is my responsibility and what part the framework provides regarding message history. I can intercept every incoming message. Then am I supposed to create and store each message inside a Messages table using core data? I'd have a Message Entity. And each XMPPUser would have an array of Message objects. But then wouldn't I be rolling my own solution, which would be working against the framework?

Thanks!

解决方案

I know this is an old thread but as I am currently working with XMPP on iOS I must say that there is a built in support for archiving messages in XMPP.

I downloaded the XMPP framework for iOS and in it there is folder marked XEP-0136. Import the folders in XCode and activate client side archiving by using the following lines of code in the class you instantiate XMPP client:

xmppMessageArchivingStorage = [XMPPMessageArchivingCoreDataStorage sharedInstance];
xmppMessageArchivingModule = [[XMPPMessageArchiving alloc] initWithMessageArchivingStorage:xmppMessageArchivingStorage];

the following one line of code saves you from sending archive specific stanzas to the xmpp server which will most probably respond with service-not-implemented

[xmppMessageArchivingModule setClientSideMessageArchivingOnly:YES];

[xmppMessageArchivingModule activate:xmppStream];
[xmppMessageArchivingModule  addDelegate:self delegateQueue:dispatch_get_main_queue()];

And you are set. From that moment on, messages (outgoing and incoming) will be stored in a table created by the framework.

If you need more info please comment and i will get back to you.

I did like this :

-(void)testMessageArchiving{
            XMPPMessageArchivingCoreDataStorage *storage = [XMPPMessageArchivingCoreDataStorage sharedInstance];
            NSManagedObjectContext *moc = [storage mainThreadManagedObjectContext];
            NSEntityDescription *entityDescription = [NSEntityDescription entityForName:@"XMPPMessageArchiving_Message_CoreDataObject"
                                                                 inManagedObjectContext:moc];
            NSFetchRequest *request = [[NSFetchRequest alloc]init];
            [request setEntity:entityDescription];
            NSError *error;
            NSArray *messages = [moc executeFetchRequest:request error:&error];

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

-(void)print:(NSMutableArray*)messages{
         @autoreleasepool {
            for (XMPPMessageArchiving_Message_CoreDataObject *message in messages) {
                NSLog(@"messageStr param is %@",message.messageStr);
                NSXMLElement *element = [[NSXMLElement alloc] initWithXMLString:message.messageStr error:nil];
                NSLog(@"to param is %@",[element attributeStringValueForName:@"to"]);
                NSLog(@"NSCore object id param is %@",message.objectID);
                NSLog(@"bareJid param is %@",message.bareJid);
                NSLog(@"bareJidStr param is %@",message.bareJidStr);
                NSLog(@"body param is %@",message.body);
                NSLog(@"timestamp param is %@",message.timestamp);
                NSLog(@"outgoing param is %d",[message.outgoing intValue]);
            }
        }
}

Hope it helps :)
