How to get friends from XMPPRoster?

Question

I try like this:

XMPPRosterMemoryStorage *xmppRosterMemStorage = [[XMPPRosterMemoryStorage alloc] init];
XMPPRoster *xmppRoster = [[XMPPRoster alloc] initWithRosterStorage:xmppRosterMemStorage
                                         dispatchQueue:dispatch_get_main_queue()];
[xmppRoster addDelegate:self delegateQueue:dispatch_get_main_queue()];
xmppRoster.autoAcceptKnownPresenceSubscriptionRequests = true;
xmppRoster.autoFetchRoster = true;
[xmppRoster activate:xmppStream];
[xmppRoster fetchRoster];

But xmppRoster is empty. Why?

Answer 1

Roster items are stored in [xmppRosterMemStorage mainThreadManagedObjectContext], you can use it with NSFetchedResultsController as datasource for your UITableView, see iPhoneXMPP example in the XMPPFramework sources
