Is it correct to use short syntax when initializing NSMutableArray?

Question

Usually when we want to initialize NSMutableArray we use:

NSMutableArray *mArr = [[NSMutableArray alloc] initWithObjects: @\"one\", @\"two\", @\"thr         


        

Answer 1

I usually use arrayWithArray.

NSMutableArray *foo = [NSMutableArray arrayWithArray:@[@"one", @"two", @"three"]];

Answer 2

But I think the second way to be way more readable

Personally, I find it more confusing, and even more confusing since you are using mutableCopy as if it was a property. Correct, correct, but totally misleading IMHO.

Why not just take advantage of inheritance?

NSMutableArray *ma = [NSMutableArray arrayWithObjects:@"foo", @"bar", nil];

_{Sometimes collections which are mutable by default would be of more use. * sigh *}

Answer 3

Yes, it's ok to initialize your mutable array that way, if you are willing (as you indicated) to pay the performance cost. ARC will clean everything up appropriately. It won't leak.
