Hi all,
I have been deleting objects with code similar to this.
NSManagedObjectContext *context = [[self fetchedResultsController]
managedObjectContext];
[context deleteObject:videoEntity];
[managedObjectContext processPendingChanges];
//commit the delete
NSError *saveError = nil;
if (![context save:&saveError])
{
NSLog(@"CoreData Failure");
}else {
//all good
NSLog(@"CoreData delete success");
NSLog(@"\n\nNumber of objects in store after delete: %d\n\n",
[[self.fetchedResultsController fetchedObjects] count]);
}
This works fine (as far as deleting the entry) however it crashes with a crash
like that shown below: I also saw a recommendation to add this:
- (void)controllerDidChangeContent:(NSFetchedResultsController *)controller
{
NSLog(@"controllerDidChangeContent");
}
This seems to make no difference to the crash.
