Thank you Robert and Amritendu, now I understand.
I have one more question. In the same code there is
// Standard accessors
- (Track *)track
{
return [[track retain] autorelease];
}
Why not just
// Standard accessors
- (Track *)track
{
return track;
}

Hi Bob,
you're right, it's completely sufficient to release track object.
However, setting it to nil helps tracking possible bugs in your code,
because you will immediately see in the debugger that you are sending
messages to nil object.
