In a Garbage Collected App when using the @property is it correct that I still
have to specify (copy) or (retain) or have I missed something? I thought using
GC didn't require retain and that everything could just be assigned, but the
complier complains.
You're correct; GC doesn't require retain, and retain in a GC
environment is a no-op.
In general, however, I'd suggest ignoring whether the
environment is GC or not. Specify assign, copy, or retain based
on the usage pattern of the property. That way, if you find
yourself in a non-GC environment, it will still work.
While I write my properties this way, I may omit the
retain/release messages in my code if I'm _sure_ it will never
see a non-GC environment. But even when I'm writing a GC
application, if the classes have utility beyond this
application, and there's a reasonable chance that I'd like to
use them in a non-GC environment, I'll write full retain/release
code so that's functional in both.
