Autorelease pools are not scoped to any particular class or function, so probably not, unless you're using the library in an application that doesn't have an autorelease pool, which would be pretty rare. You would also need to create a new pool in any thread other than the main one, and drain it at thread exit.
If an object gets autoreleased and there is no autorelease pool in place for it, you'll see a big warning in the console, so just look for those. If you don't see one, then you're OK.
