Declaring object type as NSManagedObject or class name

Question

In Core Data, if I have a Person entity is there any difference between:

NSManagedObject *aPerson = [NSEntityDescription insertNewObjectForEntityForName:@"Person" inManagedObjectContext:[self managedObjectContext]];

or

Person *aPerson = [NSEntityDescription insertNewObjectForEntityForName:@"Person" inManagedObjectContext:[self managedObjectContext]];

Should aPerson be of type Person or NSManagedObject? Is there a difference?

Answer 1

You should declare it as aPerson class. That way the complier know the exact class type.
