iOS CoreData NSPredicate to query multiple properties at once

Question

I am trying to use a UISearchBar to query multiple properties of a NSManagedObject I have a NSManagedObject called Person

Answer 1

You can append multiple search terms in an NSPredicate using the usual boolean operands such as AND/OR.

Something like this should do the trick.

[NSPredicate predicateWithFormat:@"name contains[cd] %@ OR ssid contains[cd] %@", query, query];

Hope that helps :)

Answer 2

Complete solution for Swift2

let request = NSFetchRequest(entityName: "Location")
let subPredicate1 = NSPredicate(format: "(name = %@)", searchString)
let subPredicate2 = NSPredicate(format: "(street = %@)", searchString)
let subPredicate3 = NSPredicate(format: "(city = %@)", searchString)

request.predicate = NSCompoundPredicate(type: .OrPredicateType, subpredicates: [subPredicate1, subPredicate2, subPredicate3])
