How to fetch array of objects using array of ids using core data?

问题

I have an array of ids. I want to fetch core data entity for the items in the ids array. How can we implement that using NSFetchRequest?

回答1:

Use NSPredicate

fetchRequest.predicate = NSPredicate(format: "itemId IN %@", itemIds)

Instead of itemId set your actual id property name. Now perform a fetch with this fetch request

回答2:

let hrData = self.cstProjectDetails as NSArray
