Question

I am struggling to find a shorthand version of the code shown below. Basically I am saving Events into core data. Each event has up to 15 contacts. newEvent is from an Event class.

The code below works great, but I don’t want to have it duplicated 15 times for each contact. Is there an easier way?

if ([[selectedContacts objectAtIndex:14] objectAtIndex:0] != (id)[NSNull null]) {
    newEvent.contact15 = [[selectedContacts objectAtIndex:14] objectAtIndex:0];
}
else {
    newEvent.contact15 = @"";
}

You can use this code

-(void) Solve{
    for (int i = 0 ; i < 15 ; i++){
        Contact *con = [newEvent.contacts objectAtIndex:14 - i];
        if ([[selectedContacts objectAtIndex:14 - i] objectAtIndex:0] != (id)[NSNull null]) {
            con = [[selectedContacts objectAtIndex:14 - i] objectAtIndex:0];
        }
        else {
            con = @"";
        }
    }
}

just you should define contact in your newEvent class as Array
