the method: - (XMPPUserCoreDataStorageObject *)myUserForXMPPStream:(XMPPStream *)stream managedObjectContext:(NSMangedObjectContext *)moc is unuseful?

[jackywpy]

I call this method to get a XMPPUserCoreDataSorageObject, result is nil; I find this method wants to get myuser from rosters through myJID, but the roster doesn't contain myJID, so, is it unuseful?

[ObjColumnist]

I can't see a reason for it myself.

You can add yourself to roster, and this method should work. I think better implementation will return XMPPUser instance in both cases, even I have myself in roster or not.

@vitalyster @ObjColumnist How to add myself to roster?In logic, myself should not be in roster, right?

[vitalyster]

@jackywpy as any other contact - send subscription request to your own JID and then approve it
