NSFetchedResultsControllerDelegateでこのエラーが発生し続けます。
それは散発的に起こるので、それをどうするかわからない。
同期してレコードを作成しますが、それでも..
なぜこれができるのか?
- (Activity *)createActivityWithDictionary:(NSDictionary*)dict
{
@synchronized([DBController sharedManaged])
{
Activity *act = [Activity activityWithDictionary:dict inManagedObjectContext:self.managedObjectContext];
[self saveContext];
return act;
}
}
