Re: Why shouldn't I release?

The result of -[retainCount] is not necessarily equal to its retain 
count from your point of view. It might be retained by something else 
that's not immediately obvious. For instance, your outputString will 
be released by the autoreleasepool. So yes, the retain count may be 
higher than 0, but that still means it's not up to you to do something 
about that in this case.

Good luck,
Hank
