ios应用由于XMPPMessageArchiving而崩溃

Question

I added Message Archiving for XMPP chat im my app.

After that, my app crashes when I send/receive message in XMPP chat. App crashes only when I run it on device without connect to laptop (xcode). When I debug the app in xcode, there are no crashes.

I connected all necessary XMPP classes and directories to my project.

I setup XMPPMessageArchivingCoreDataStorage and XMPPMessageArchiving instances:

xmppMessageArchivingStorage = [XMPPMessageArchivingCoreDataStorage sharedInstance];

xmppMessageArchivingModule = [[XMPPMessageArchiving alloc] initWithMessageArchivingStorage:xmppMessageArchivingStorage];
[xmppMessageArchivingModule setClientSideMessageArchivingOnly:YES];

I activate XMPPMessageArchiving instance:

[xmppMessageArchivingModule activate:xmppStream];

and add delegate:

[xmppMessageArchivingModule addDelegate:self delegateQueue:dispatch_get_main_queue()];

Also, I do:

[xmppMessageArchivingModule removeDelegate:self];
[xmppMessageArchivingModule deactivate];
xmppMessageArchivingModule = nil;
xmppMessageArchivingStorage = nil;

What it the reason of crashes?
