Question

我在AppDelegate.m中实现了以下方法。

- (BOOL)xmppStream:(XMPPStream *)sender didReceiveIQ:(XMPPIQ *)iq

有人可以告诉我这个方法在哪种情况下被调用，这个方法的目的是什么？

谢谢。

Answer 1

试试这个以获取名单

-(void)fetchRosterListWithUserId:(NSString *)userId // yourID
    {
        NSXMLElement *query = [NSXMLElement elementWithName:@"query" xmlns:@"jabber:iq:roster"];
        XMPPIQ *iq = [XMPPIQ iq];
        [iq addAttributeWithName:@"id" stringValue:FETCH_ROSTER_DISCO_ID];
        [iq addAttributeWithName:@"to" stringValue:userId];
        [iq addAttributeWithName:@"type" stringValue:@"get"];
        [iq addChild:query];
        [_xmppStream sendElement:iq];
    }

您可以在

中获取回复

- (BOOL)xmppStream:(XMPPStream *)sender didReceiveIQ:(XMPPIQ *)iq`

Answer 2

这将被调用为任何XMPP查询（XMPPIQ）的响应，如

  NSXMLElement *query = [NSXMLElement elementWithName:@"query" xmlns:SERVER_DISCO_ITEMS];
    XMPPIQ *iq = [XMPPIQ iq];
    [iq addAttributeWithName:@"id" stringValue:FETCH_SERVER_DISCO_ID];
    [iq addAttributeWithName:@"to" stringValue:serverName];
    [iq addAttributeWithName:@"type" stringValue:@"get"];
    [iq addChild:query];
    [_xmppStream sendElement:iq];

作为对此的回应，您可以通过回复来回复

- (BOOL)xmppStream:(XMPPStream *)sender didReceiveIQ:(XMPPIQ *)iq

例如，当您的朋友从朋友列表中删除您的帐户时，系统会调用此信息。
