好友列表和好友名片

1. [_xmppRoster fetchRoster];//获取好友列表
3. //获取到一个好友节点
4. - (void)xmppRoster:(XMPPRoster *)sender didRecieveRosterItem:(NSXMLElement *)item
6. //获取完好友列表
7. - (void)xmppRosterDidEndPopulating:(XMPPRoster *)sender
9. //到服务器上请求联系人名片信息
10. - (void)fetchvCardTempForJID:(XMPPJID *)jid;
12. //请求联系人的名片，如果数据库有就不请求，没有就发送名片请求
13. - (void)fetchvCardTempForJID:(XMPPJID *)jid ignoreStorage:(BOOL)ignoreStorage;
15. //获取联系人的名片，如果数据库有就返回，没有返回空，并到服务器上抓取
16. - (XMPPvCardTemp *)vCardTempForJID:(XMPPJID *)jid shouldFetch:(BOOL)shouldFetch;
18. //更新自己的名片信息
19. - (void)updateMyvCardTemp:(XMPPvCardTemp *)vCardTemp;
21. //获取到一盒联系人的名片信息的回调
22. - (void)xmppvCardTempModule:(XMPPvCardTempModule *)vCardTempModule
23. didReceivevCardTemp:(XMPPvCardTemp *)vCardTemp
24. forJID:(XMPPJID *)jid
    添加好友
    [cpp]
    1. //name为用户账号
    2. - (void)XMPPAddFriendSubscribe:(NSString *)name
    3. {
    4. //XMPPHOST 就是服务器名， 主机名
    5. XMPPJID *jid = [XMPPJID jidWithString:[NSString stringWithFormat:@%@@%@,name,XMPPHOST]];
    6. //[presence addAttributeWithName:@subscription stringValue:@好友];
    7. [xmppRoster subscribePresenceToUser:jid];
    9. }
       [cpp] view plaincopyprint
       1. //收到添加好友的请求
       2. - (void)xmppRoster:(XMPPRoster *)sender didReceivePresenceSubscriptionRequest:(XMPPPresence *)presence
       3. {
       4. //取得好友状态
       5. NSString *presenceType = [NSString stringWithFormat:@%@, [presence type]]; //online/offline
       6. //请求的用户
       7. NSString *presenceFromUser =[NSString stringWithFormat:@%@, [[presence from] user]];
       8. NSLog(@presenceType:%@,presenceType);
       10. NSLog(@presence2:%@ sender2:%@,presence,sender);
       12. XMPPJID *jid = [XMPPJID jidWithString:presenceFromUser];
       13. //接收添加好友请求
       14. [xmppRoster acceptPresenceSubscriptionRequestFrom:jid andAddToRoster:YES];
       16. }
           
           删除好友
           [cpp]
           1. //删除好友，name为好友账号
           2. - (void)removeBuddy:(NSString *)name
           3. {
           4. XMPPJID *jid = [XMPPJID jidWithString:[NSString stringWithFormat:@%@@%@,name,XMPPHOST]];
           6. [self xmppRoster] removeUser:jid];
           7. }
