XMPPFramework 服务器功能

Question

我正在尝试获取服务器功能，XMPP 配置为：

 _xmppCapabilitiesStorage = [XMPPCapabilitiesCoreDataStorage sharedInstance];
_xmppCapabilities = [[XMPPCapabilities alloc] initWithCapabilitiesStorage:_xmppCapabilitiesStorage];
_xmppCapabilities.autoFetchMyServerCapabilities = YES;

日志说：

SEND: 
<?xml version="1.0" encoding="utf-8"?>
<iq type="get" to="myserver.im" id="4FE37B35-8078-41B0-BCAF-DC6CFF04DD33">
    <query xmlns="http://jabber.org/protocol/disco#info"/>
</iq>

收到：

稍后如何查看哪些功能确实存在？我在 XMPPCapabilities 或 XMPPCapabilitiesCoreDataStorage 中没有看到任何功能列表。我错过了什么吗？例如，我想检查 <feature var="urn:myserver:im:filetransfer"/> 是否存在。 XMPPFramework 在哪里保存和保存功能列表？非常感谢任何提示。

好的，我找到了信息的存储位置：

NSManagedObjectContext *moc = [[XMPPCapabilitiesCoreDataStorage sharedInstance] mainThreadManagedObjectContext];
NSEntityDescription *entityDescription = [NSEntityDescription entityForName:@"XMPPCapsResourceCoreDataStorageObject"
                                                     inManagedObjectContext:moc];
NSFetchRequest *fetchRequest = [NSFetchRequest new];
[fetchRequest setEntity:entityDescription];
fetchRequest.fetchBatchSize = 30;
NSPredicate *filter = [NSPredicate predicateWithFormat:@"jidStr == %@", _domain];
fetchRequest.predicate = filter;
NSError *error = nil;
NSArray *features = [moc executeFetchRequest:fetchRequest error:&error];
NSArray *ch = [[[[features firstObject] caps] capabilities] children];
