Which type I should use to save many objects with same key? (iOS)
{
  @"suggestedTo" = 111,
  @"suggestedTo" = 222,
  @"suggestedTo" = 333,
  etc.
}

NSSet *suggestedTo = [NSSet setWithObjects:[NSNumber numberWithInt:111],
                                           [NSNumber numberWithInt:222],
                                           [NSNumber numberWithInt:333], nil];
NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:suggestedTo,
                                                                @"suggestedTo", nil];

NSArray      *suggestedTos = [[NSArray alloc] initWithObjects:
                               [NSNumber numberWithInt:111],
                               [NSNumber numberWithInt:222],
                               [NSNumber numberWithInt:333], nil];

NSDictionary *myDictionary = [[NSDictionary alloc] initWithObjectsAndKeys:
                               suggestedTos, @"suggestedTo", nil];
