Passe data beetwen view controller in UITableView

I try to pass an PFObject with the current ViewController to another ViewController when the user select a cell from the UITableView, this is my code :

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *identifier = @"boxCell";
NSInteger row = [indexPath row];
boxTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier];
if(cell == nil){
    cell = [[boxTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier];
}

PFObject *boxe = [PFObject objectWithClassName:@"Boxe"];
boxe = [self.arrayBox objectAtIndex:row];


PFQuery *query = [PFQuery queryWithClassName:@"Boxe"];
[query whereKey:@"objectId" equalTo:boxe.objectId];

[query getFirstObjectInBackgroundWithBlock:^(PFObject *object, NSError *error) {
    if(object){
        // I instanciate the PFObject
        box = object;
        cell.nomBoxe.text = object[@"contenu"];
        cell.qteBoxe.text = [NSString stringWithFormat:@"%@ boxes disponbiles",object[@"quantite"]];
        cell.prixBoxe.text = [NSString stringWithFormat:@"%@€",object[@"prix"]];
        cell.descriptionBoxe.text = object[@"description"];
    } else {
        NSLog(@"Erreur lors de chargement, erreur : %@",error.description);
    }
}];
return cell;
}

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
[self performSegueWithIdentifier:@"segueToBoxDetail" sender:self];
}


-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
if ([[segue identifier] isEqualToString:@"segueToBoxDetail"]) {
    boxDetailViewController *boxDetailVC = [segue destinationViewController];
    boxDetailVC.box = box;
    }
}

I declare the PFObject :

@implementation RestauCardViewController{
PFObject *box;
}

In the other ViewController, I have a property for the object box :

@property(nonatomic) PFObject *box;

I got this error :

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIViewController setBox:]: unrecognized selector sent to instance 0x12aad9100'

Any help please
