使用iOS中的XMPP框架匿名进行身份验证

Question

我想在iOS中使用xmpp框架匿名连接到openfire服务器.我可以通过提供JID和PW连接到开火.但是,当我尝试匿名连接时,它说"服务器不支持匿名身份验证".

我在xib文件中使用了一个按钮.当点击下面的代码时执行:

- (IBAction)login:(id)sender {

    [[self appDelegate]connect];

    NSError *authenticationError = nil;
    [self.xmppStream authenticateAnonymously:&authenticationError];
}

以下是connect方法的代码:

- (BOOL)connect {

    [self setupStream];
    xmppStream.hostName = @"abc.xyz.com";
    //xmppStream.hostName = @"Virtuals-MacBook-Pro.local ";

    NSString *jabberID = [[NSUserDefaults standardUserDefaults] stringForKey:@"userID"];
    NSString *myPassword = [[NSUserDefaults standardUserDefaults] stringForKey:@"userPassword"];

    if (![xmppStream isDisconnected]) {
        return YES;
    }

    if (jabberID == nil || myPassword == nil) {

        return NO;
    }

    [xmppStream setMyJID:[XMPPJID jidWithString:jabberID]];
    password = myPassword;

    NSError *error = nil;
    if (![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];
        //[alertView release];


        return NO;
    }

    return YES;
}

匿名身份验证的步骤:

1-首先连接xmpp-stream,然后匿名进行身份验证.

[[self xmppStream] authenticateAnonymously:&error];

那么你将被匿名认证.但是一件非常重要的事情.在进行身份验证之前,获取已注册用户的用户名和密码并连接到xmpp-stream
