NSPredicate that is the equivalent of SQL's LIKE

Question

I\'m looking for a way to use NSPredicate to set a LIKE condition to fetch objects. In addition to that, an OR would be useful as well

Answer 1

NSString *_mySearchKey = @"James";
NSPredicate *_myPredicate = [NSPredicate predicateWithFormat:@"(firstname CONTAINS[cd] %@) OR (lastname CONTAINS[cd] %@)", _mySearchKey, _mySearchKey];
