App Crashes with SKPSMTPMessage class

Question

So I'm having a serious issue with this class...

Currently, when the user actually sends an email out, the ActivityIndicator shows... great!!! as well as the UI not being frozen... Thats cool!

Issue is, if the user pushes to another viewcontroller which actually dismisses the send email viewcontroller, the app crashes... I notice I have to wait until the SECOND "*** stopping watchdog ***" string has been logged... as well as this "S: 221 2.0.0 closing connection i16sm31117760pag.18 - gsmtp"

Heres the full log,

Now, I "really fast" exit the view that sends the email and it continues to send the email, then I get this message *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFType messageSent:]: unrecognized selector sent to instance 0xa0a8e50'

That occurs when I use [testMsg performSelectorOnBackgroundThread:@selector(send) withObject:nil];

But when I use [testMsg performSelectorOnMainThread:@selector(send) withObject:nil waitUntilDone:YES]; I get the same issue as the log statement as posted first...

Sorry for my horrible phrasing but I'm just a bit frustrated with this bug :(.

I guess the bug doesn't lay in sending the mail via SMTP. It seems that the delegate-object has been release before the messageSent: delegate method is beeing called.

My suggestion would be to perform the SKPSMTPMessage send operation in the Application Delegate. If you don't want the SMTP Message send handle to be in the app-delegate, retain your delegate object until the mail has been sent or set the delegate of the SKSMTPMessage to nil, when the delegate object is beeing deallocated.

Hope it helps
