XMPPFramework(三)好友添加与接受

添加好友

加好友其实就是和别人建立关系,也就是xmpp的订阅,那么我们就要找个方法和别人发生点什么~ ~ ~ 那就是下面这个方法了:

 XMPPJID *jid = [XMPPJID jidWithUser:self.friendSearchTextField.text domain:KDomin resource:kResource];
  [[XMPPManager sharedInstance].roster subscribePresenceToUser:jid];

这里的roster是XMPPRoster的一个实例,要在初始化的时候激活

//实例化XMPPRoster
self.roseterDataStorage = [XMPPRosterCoreDataStorage sharedInstance];
self.roster = [[XMPPRoster alloc]initWithRosterStorage:self.roseterDataStorage dispatchQueue:dispatch_get_main_queue()];
//激活
[self.roster activate:self.stream];
[self.roster addDelegate:self delegateQueue:dispatch_get_main_queue()];

同意/拒绝好友请求

好了,约会请求已经发送了,那么小姐姐是如何收到你的约会邀请的呢?
在xmppRosterDelegate代理方法里有这么一个方法

- (void)xmppRoster:(XMPPRoster *)sender didReceivePresenceSubscriptionRequest:(XMPPPresence *)presence
{
    //好友申请,from:发送好友的jid
    self.subscrptionRequestJID = presence.from;
    
    UIAlertView *alertview = [[UIAlertView alloc] initWithTitle:@"添加好友申请" message:presence.from.user delegate:self cancelButtonTitle:@"拒绝" otherButtonTitles:@"同意并添加对方", nil];
    [alertview show];
    //在alertview的代理方法中处理添加请求
 }

#pragma mark --UIAlertViewDelegate

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
    switch (buttonIndex) {
        case 0:
            //拒绝
            [self.roster rejectPresenceSubscriptionRequestFrom:self.subscrptionRequestJID];
            break;
        case 1:
            //同意
             [self.roster acceptPresenceSubscriptionRequestFrom:self.subscrptionRequestJID andAddToRoster:YES];
            
        default:
            break;
    }
    self.subscrptionRequestJID = nil;
}

收到对方处理回执

到这里有人肯定要问了:说小姐姐到底跟我约不约啊,我咋知道呢?
在XMPPStreamDelegate里有这么个方法,当别人在线状态改变,或者接受,婉拒了你的请求,它会收到通知

- (void)xmppStream:(XMPPStream *)sender didReceivePresence:(XMPPPresence *)presence
 {
     //上线状态 - "available"
     //离线状态 - "unavailable"
     //同意 - "subscribed"
     //拒绝 - "unsubscribed"

     if ([presence.type isEqualToString:@"subscribed"]) {
         [self showAlertWithTitle:[NSString stringWithFormat:@"%@同意了您的请求",presence.from.user]];
         //刷新列表
     }else if ([presence.type isEqualToString:@"unsubscribed"]) {
         [self showAlertWithTitle:[NSString stringWithFormat:@"%@拒绝了您的请求",presence.from.user]];
     }

 }

好了,到这里差不多就大结局了! 啥?你说啥?
"大结局后通常应该有点彩蛋"
"哦,那我准备一下"

//其实吧添加好友还有这么一个方法
[[XMPPManager sharedInstance].roster addUser:jid withNickname:jid.user]
