关于objective C：iOS XMPP 框架 XMPPStream 未连接？

iOS XMPP Framework XMPPStream Not Connecting?

我正在尝试使用 iOS 上的 XMPPFramework 连接到公共 XMPP 服务器。当应用程序加载到

中时，我设置了连接

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
// Set up XMPP stream

self.xmppStream = [[XMPPStream alloc] init];
[self.xmppStream addDelegate:self delegateQueue:dispatch_get_main_queue()];

self.xmppStream.hostName = @"jabber.web.id";
self.xmppStream.hostPort = 5222;

[self connect];

连接中：

- (void)connect {
NSString *username = @"eric1234";
self.password = @"test123";

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

NSError *error = nil;
if (![self.xmppStream oldSchoolSecureConnectWithTimeout: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];
}

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

然后是我的委托方法：

- (void)xmppStreamDidConnect:(XMPPStream *)sender {
NSError *error = nil;
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];
}
[self.xmppStream sendElement:[XMPPPresence presence]];
}

xmppStreamDidConnect 永远不会被调用。我不知道为什么，我已经使用服务器上的桌面 XMPP 客户端在 jabber.web.id 上成功注册了 eric1234。有什么想法吗？
