With ARC turned on, is there a different between alloc/init and normal autorelease methods?

Question

What is the different between these two when using ARC in Objective-C for iOS?

NSMutableArray *anArray = [[NSMutableArray alloc] initWithArray:itemsArray];
appDelegate.wishlistItemsArray = anArray;

vs

appDelegate.wishlistItemsArray = [NSMutableArray arrayWithArray:itemsArray];

The property in appDelegate is:

@property (nonatomic, strong) NSMutableArray *wishlistItemsArray;

FYI - another option is: `appDelegate.wishlistItemsArray = [itemsArray mutableCopy];` — rmaddy, Jun 13 '13 at 00:38

Nope. Those methods differ only in the memory management semantics of their return value, and ARC handles memory management for you, they can be used interchangeably in an ARC program.
