No. You took ownership of the NSSavePanel when you created it by
using a convenience constructor. You must retain it, and release it
when you're done with it.
Except that the NSSavePanel docs state:
"An NSSavePanel object is a singleton: when you request a Save
panel, NSSavePanel tries to reuse an existing Save panel rather than
create a new one"
I don't usually retain it and have never seen this crash... but I
also see it says TRIES to... so maybe it creates new instances
sometimes depending on the parameters. It would be good to have a
bit more certainty in the docs on this one - is it a singleton or
not, and if not, under what circumstances exactly is that?
Don't care about this. IF it is a singleton, retaining is no problem.
IF it is NOT, retaining is the right way to handle it.
However, as Cate said: You are the owner and you have to take care
about it. What $somebodyelse is does is not your problem.
@TS
A -retain is no memory leak. A -retain without -release is a memory
leak.
