No, you don’t need to release ‘nodes' since you didn’t allocate or copy it.

Are you calling that method as part of a loop? If so, try allocating an
autorelease pool at the top of the loop and draining it at the end. Basically,
autoreleased objects don’t go away till the topmost autorelease pool drains,
and if you’re doing a whole lot of stuff before returning to the event loop,
you need to set up your own autorelease pool or everything will pile up till
you finally finish.
In general it looks something like:
while (…) {
NSAutoreleasePool* pool = [NSAutoreleasePool new];
… do stuff …
[pool drain];
}
‘pool’ will collect all the references that get autoreleased during ‘do stuff’,
and then release them when it’s drained.
