Hi,
if you think you've found a memory leak inside of CoreAnimation,
please file a radar (bugreporter.apple.com) with a project showing the
leak, and we'll look into it. thanks,
John

I would consider that to be expected behavior. If you aren't ever

the layers you created, why would any of the relevant memory be
freed? The
timer and the animations it is causing to be performed should not
really be
incurring a very significant memory footprint in addition to what
the layers
on their own are already using (my own observations at least
indicate that
running the test app with or without the timer makes very little
difference
in that regard).
Are the two methods you posted really the only two methods in your
entire
test app? Or are you doing something else somewhere in addition to
this?
Feel free to e-mail me the test project off-list if you like.

Yes, these 2 methods are my entire test app. I will email you the
project
off-list.
I don't think it has to do with layer release.
If I run it without the animation (commented out the timer
creation), the
memory usage in Object Alloc is constant (as expected) at 1.8MB
When I add the timer, the memory usage starts at 1.8MB and goes up
to 3MB
after 1 minute, 5MB after 2 minutes, and so on.
The only difference between these 2 cases is "[NSTimer
scheduledTimerWithTimeInterval:0.4 target:self
selector:@selector(fromTimer:)
userInfo:nil repeats:YES];" being commented out.
Thanks
Stephane
