ios xmppframework没有发送存在

Question

我的XMPP流成功连接，在回调中，我尝试发送用户的存在。但是，我继续收到此错误：错误域= xmppstreamerrordomain代码= 1“操作无法完成。（xmppstreamerordomain错误1。）”

我的Connect方法：

- (void)connect {
    NSString *username = @"masa060295@jabber.web.id";
    self.password = @"test123";

    [self.xmppStream setMyJID:[XMPPJID jidWithString:username]];

    NSError *error = nil;
    if (![self.xmppStream connectWithTimeout:XMPPStreamTimeoutNone error:&error])
    {
        UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error"
                                                            message:[NSString stringWithFormat:@"Can't connect to server %@", [error localizedDescription]]
                                                           delegate:nil
                                                  cancelButtonTitle:@"Ok"
                                                    otherButtonTitles:nil];
        [alertView show];
    }
}

.

我的回调：

- (void)xmppStreamDidConnect:(XMPPStream *)sender {
    NSError *error = nil;

    NSLog(@"%hhd", [self.xmppStream isConnected]);

    if (![self.xmppStream authenticateWithPassword:self.password error:&error]) {
        UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error"
                                                            message:[NSString stringWithFormat:@"Can't authenticate %@", [error localizedDescription]]
                                                           delegate:nil
                                                  cancelButtonTitle:@"Ok"
                                                  otherButtonTitles:nil];
        [alertView show];
    }

    XMPPPresence *presence = [XMPPPresence presence];
    NSXMLElement *priority = [NSXMLElement elementWithName:@"priority" numberValue:[NSNumber numberWithInt:127]];
    [presence addChild:priority];

    [self.xmppStream sendElement:presence];
}

.

任何想法？

Answer 1

您应该在身份验证完成后发送存在。在此回调中进行：

 - (void)xmppStreamDidAuthenticate:(XMPPStream *)sender
 {        
      XMPPPresence *presence = [XMPPPresence presence]; // type="available" is implicit

      [sender sendElement:presence];
 }
