How can i copy a MutableArray in the same zone as the old one?

Question

How can i add a mutable array in the same like the old one?

I tried this code but it doesn't work:

 - (void)didParsingApiBusinesses:(NSMutableArray *)businesses
 {
     NSZone *zone = [entriesBusinessesArray zone];
     entriesBusinessesArray = [businesses mutableCopyWithZone:zone];
 }

Answer 1

Two things:

1. Zones aren't used by the framework anymore.
2. You shouldn't call mutableCopyWithZone: directly; instead call mutableCopy.

So all you need is:

- (void)didParsingApiBusinesses:(NSMutableArray *)businesses
{
    entriesBusinessesArray = [businesses mutableCopy];
}

Answer 2

Use mutableCopy directly.

I think NSZone is not supported by objective C now.

Thank you.
