Mitsuhiro,
If you are using NSTimer with the target: set to point to an instance
of your TestAudioUnit_CocoaView, then the behavior you describe is
probably exactly as expected. This is exactly what Tahome was trying
to point out.
I think perhaps you should look into breaking down the NSTimer, maybe
before and after a new preset is loaded. Or look for a code path
where the NSTimer is possibly holding on to a reference for the
TestAudioUnit_CocoaView.
Keep in mind that -dealloc is only ever called once, and that's after
every reference has been released. If the NSTimer is holding on to
the TestAudioUnit_CocoaView instance as its target, then the
TestAudioUnit_CocoaView will never be released.
In other words, you have some decent debugging in there, but you
might want to do some additional debugging with regard to the NSTimer
(or any other mechanism which might retain your
TestAudioUnit_CocoaView instance).

Normaly, when CocoaView will appear, "setAU was called." log is

But after I select preset from plugin's preset menu,
even if I remove the plugin from Logic, CocoaView's dealloc log
wasn't written.
So I think this is Logic's bug.

I'd start by overriding -release and -retain to see if this is really
a Logic problem and not just something that was there all along and
gets exposed in the latest version. Keep in mind that NSTimer retains
its parent class, so you might end up with a situation where neither
gets dealloc'd.

Hi, there.
I found that after I select preset from plugins menu, then Cocoa
UI's dealloc wasn't called.
So, My plugin leaks resources. Actually I need to use NSTimer, so
when
I use select menu, NSTimer leaked, and I got messy result.
This problem is reproduced only on Logic 9.1.3.
Logic 9.0.0 or Logic 9.1.0 doesn't have this problem.
So, I think this is bug of Logic 9.1.3
