How to join two strings for NSPredicate, ie firstname and lastname

Question

I have a Person Object which has two NSString properties; firstName and lastName. I\'m currently using an NSPredicate like so

Answer 1

you can concatenate the fields into two common fields (firstLastName and lastFirstName )

- (NSString *)firstLastName {
      return [NSString stringWithFormat:@"%@ %@", self.firstName, self.lastName];
}

- (NSString *)lastFirstName {
      return [NSString stringWithFormat:@"%@ %@", self.lastName, self.firstName];
}

and then filter on this fields using 'contains[cd]'

[NSPredicate predicateWithFormat:@"(firstLastName contains[cd] %@) OR (lastFirstName contains[cd] %@)" , self.searchBar.text, self.searchBar.text];
