I am still getting to grips with objective C, coming from a C++ background, and
I'm stuck on a particular aspect of the base class/subclass model that I hope
somebody can help me with.
I need an object representing a video camera plugged into the mac, a camera
which may be one of several models

Thanks, applicationShouldTerminateAfterLastWindowClosed works.
Now I'd like to prompt user if he really wants to quit, if not, return NO, that
seems working as well.

I've just been looking back at some code that has been working fine for me for
a while, and as far as I can see it shouldn't actually work! I'd be interested
for peoples' comments. The code is as follows:

Blocks do retain objects that are passed in, so that's probably what's
happening. Also, keep in mind that autoreleased objects aren't freed
immediately; it happens when the run loop completes. You should always act as
if it does happen immediately, but it isn't always true.

Yes, it is very clever.
When creating the block, the ObjC compiler also specifies the Object stored

Suspicious in what way? Are you saying I am using the wrong sort of
implementation for my [frame GetNSImage], and I shouldn't be returning
something that requires an explicit release? Because I can certainly confirm

I did notice the inner block was running on a second q, that's what my comment
is about. I guess the first block what's really in questioned, how big is the

assuming you want he image transformed prior to the write.

Because you make 2 queues, doesn't mean internally they will operate on
separate cores/threads. GCD may coalesce these based on system resources. I
agree with the best practice you outlined; however, the example in this email
thread has 2 queues within the same subsystem. So there must be som

Well, the problem seems to have been fixed.
I tried replacing every instance of MRWorkspaceItemLayer with a regular CALayer
instance, and it seemed to work fine, meaning my problem was actually in the
MRWorkspaceItemLayer subclass. Seemed everytime I would unselect then select
an item, the MRW
That depends on how you define "subsystem". I see nothing wrong with the way
the op is structuring this (i.e. doing the transformation on one serial queue,

Suspicious because it clearly does not follow ObjC coding style for

If you have to call release here, it's likely because GetNSImage is
incorrect by returning an object that needs to be released.
