'string' is a pointer. In the line of code above, you've discarded its previous value (the address of the object returned by your alloc/init pair), and assigned it the address of an autoreleased string (returned from -stringByAppendingString:)

So just as a technical point, would the previous value, discarded in the stringByAppendingString assignment, be a leak?

Yes.
