How do i avoid running out of memory when performing a task on every item of core data?

Question

I\'m trying to perform a task similar to this:

NSFetchRequest *request = [NSFetchRequest fetchRequestWithEntityName:@\"Entry\"];

        NSPredicate *predicate

You guessed right. You have to use setFetchBatchSize:. This will only return the first 20 objects. If you want to get the next 20 objects, you have to set the offset using setFetchOffset:.
