如何在iOS应用程序中配置XMPP Facebook聊天

我正在开发一个使用Facebook聊天功能的iOS应用程序

（我正在使用Robbie Hanson的XMPPFramework）

在connect方法中，我已经给出了我的用户名和密码

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

    NSString *myJID = [[NSUserDefaults standardUserDefaults] stringForKey:kXMPPmyJID];
    NSString *myPassword = [[NSUserDefaults standardUserDefaults] stringForKey:kXMPPmyPassword];

    //
    // If you don't want to use the Settings view to set the JID, 
    // uncomment the section below to hard code a JID and password.
    // 

     myJID = @"example@facebook.com";
     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;
    }

在上游方法中，我给出了我的主机名和端口号

- (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];


    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:@"chat.facebook.com"];
    [xmppStream setHostPort:5222];


    // You may need to alter these settings depending on the server you're connecting to
    allowSelfSignedCertificates = NO;
    allowSSLHostNameMismatch = NO;
}

有没有我遗漏的步骤？我不知道如何进一步进行。如果有人知道解决办法，请帮助我。请帮帮我

提前感谢。

尝试使用以下方法保护连接：

[xmppStream secureConnection:(NSError *)];

在

 - (void)xmppStreamDidConnect:(XMPPStream *)sender; 

委托方法

希望有帮助。

我看到您只更改了库的示例项目。设置这些参数时，您是否可以查看聊天好友？即使我的好友列表也不会显示在应用程序中。请帮助我继续学习任何好的教程。当您在示例应用程序的“设置”页面中进行设置时，应该会显示您的好友列表。尽量不要设置主机名。您需要开始使用XMPP文档：

这里列出了一些书：

。也许你想买一个。你看过Facebook api了吗。我通过保护连接获得了输出
