Answer 1

The first and second codes are equal.

The only difference is that in second one you are creating autoreleased object of type NSString. In first one you are releasing manually object of type NSString as it is not autoreleased: [advance release];

So there are no memory management issues and you can use any of that approaches.

I would prefer second one as code will be more cleaner.
