XMPP登录通过iOS中的Gmail ID导致未经授权的错误

Question

我是XMPP框架工作的新手我遵循以下链接中提到的步骤Getting started using XMPPFramework on iOS

在XMPP安装方法中，我已经配置了我的域和端口，如下所示。

- (void)setupStream
{
    NSAssert(xmppStream == nil, @"Method setupStream invoked multiple times");
    xmppStream = [[XMPPStream alloc] init];

#if !TARGET_IPHONE_SIMULATOR
    {
        xmppStream.enableBackgroundingOnSocket = YES;
    }
#endif

    xmppReconnect = [[XMPPReconnect alloc] init];

    xmppRosterStorage = [[XMPPRosterCoreDataStorage alloc] init];
    //  xmppRosterStorage = [[XMPPRosterCoreDataStorage alloc] initWithInMemoryStore];

    xmppRoster = [[XMPPRoster alloc] initWithRosterStorage:xmppRosterStorage];

    xmppRoster.autoFetchRoster = YES;
    xmppRoster.autoAcceptKnownPresenceSubscriptionRequests = YES;

    xmppvCardStorage = [XMPPvCardCoreDataStorage sharedInstance];
    xmppvCardTempModule = [[XMPPvCardTempModule alloc] initWithvCardStorage:xmppvCardStorage];

    xmppvCardAvatarModule = [[XMPPvCardAvatarModule alloc] initWithvCardTempModule:xmppvCardTempModule];

    xmppCapabilitiesStorage = [XMPPCapabilitiesCoreDataStorage sharedInstance];
    xmppCapabilities = [[XMPPCapabilities alloc] initWithCapabilitiesStorage:xmppCapabilitiesStorage];

    xmppCapabilities.autoFetchHashedCapabilities = YES;
    xmppCapabilities.autoFetchNonHashedCapabilities = NO;

    // Activate xmpp modules

    [xmppReconnect         activate:xmppStream];
    [xmppRoster            activate:xmppStream];
    [xmppvCardTempModule   activate:xmppStream];
    [xmppvCardAvatarModule activate:xmppStream];
    [xmppCapabilities      activate:xmppStream];

    // Add ourself as a delegate to anything we may be interested in

    [xmppStream addDelegate:self delegateQueue:dispatch_get_main_queue()];
    [xmppRoster addDelegate:self delegateQueue:dispatch_get_main_queue()];

    [xmppStream setHostName:@"talk.google.com"];
    [xmppStream setHostPort:5222];

    // You may need to alter these settings depending on the server you're connecting to
    customCertEvaluation = YES;
}

在XMPP连接方法中，我的硬件代码是我的用户名和密码，如下所示

- (BOOL)connect
{
    if (![xmppStream isDisconnected]) {
        return YES;
    }
    NSString *myJID = @"myGmailID@gmail.com";
    NSString *myPassword = @"mypassword";

    if (myJID == nil || myPassword == nil) {
        return NO;
    }

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

    NSError *error = nil;
    if (![xmppStream connectWithTimeout:XMPPStreamTimeoutNone error:&error])
    {
        UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error connecting"
                                                            message:@"See console for error details."
                                                           delegate:nil
                                                  cancelButtonTitle:@"Ok"
                                                  otherButtonTitles:nil];
        [alertView show];

        DDLogError(@"Error connecting: %@", error);

        return NO;
    }

    return YES;
}

当我尝试登录服务器时，会出现以下错误

SEND: <?xml version='1.0'?>
SEND: <stream:stream xmlns='jabber:client' xmlns:stream='http://etherx.jabber.org/streams' version='1.0' to='gmail.com'>

RECV: <failure xmlns="urn:ietf:params:xml:ns:xmpp-sasl"><not-authorized/></failure>

这可能是一个愚蠢的问题，但我不知道我的代码在哪里犯了错误。
