Just wanted to shout out and say thanks to Flay for saving me! I had a DVD that I forgot to finalize, but Flay had a nice set of instructions for how to manually copy off the files from the DVD drive.
Now I can finish editing and posting the videos for the Engineering and Metaphysics conference.
I've been chasing down a wierd bug where, on an NSManagedObjectContext, the hasChanges method keeps returning YES even after a rollback. It turns out, if you do the following sequence, hasChanges will *never* be cleared:
MyClass *c = [NSEntityDescription insertNewObjectForEntityName:@"MyClass" inContext:ctx];
//Do other stuff
[ctx deleteObject:c];
// Do other stuff
[ctx rollback];
[ctx hasChanges]; // Returns YES!
In my own case, I got around it by not deleting the object, and just rolling back if I wanted it gone, but that won't work for everyone. So, I did:
MyClass *c = [NSEntityDescription insertNewObjectForEntityName:@"MyClass" inContext:ctx];
//Do other stuff
[ctx rollback]; // Don't delete! just roll back
//Do other stuff
[ctx rollback]; // Now it works
[ctx hasChanges]; // Returns NO like it should
