NSPredicate - filtering values based on a BOOLEAN stored value

Question

I have a core data model object called Entry. In this I have an attribute IsFavorite.

I would like to use an NSPredicate to filter the results of my NSFetchedResultsCont

Answer 1

If you know you're looking for a YES (and therefore don't need to switch between YES or NO in different situations), this worked for me:

[NSPredicate predicateWithFormat:@"isFavorite == 1"]
