Question

Without ARC-enabled, we write

NSArray *items = [[NSArray alloc] initWithObjects:
                  @"a",
                  @"b",
                  @"c",
                  @"d",
                  nil];

self.allItems = items;
[items release];

I just wonder whether we can take a shortcut with ARC-enabled like this:

self.allItems = [[NSArray alloc] initWithObjects:
                  @"a",
                  @"b",
                  @"c",
                  @"d",
                  nil];

Can we eliminate items when we use ARC? What’s the best practice?

Answer 1

Yes, you can eliminate the items variable if you’re using ARC. I suggest you eliminate it if you don’t need it elsewhere and you don’t think it makes your code easier to understand. I would definitely eliminate it in your example.
