It's actually normal and necessary behavior for a general-purpose
Indeed NSTask closes open descriptors in the child. I could have sworn
this was documented somewhere, but I can't seem to find the relevant
text at the moment.
To get around this behavior (and other NSTask bugs and shortcomings),
I chose to write my own NSTask equivalent. Alternatively, you could
Have you filed a bug?

Is there any way to have a process launched via NSTask access file descriptors
opened in the parent process? Other than stdin, stdout & stderr.
It looks to me like the NSTask launching machinery may close descriptors, and I
don't see a way to control that. The descriptors in question do return 0
Fritz,
Thanks for the pointer, I had over looked this document in my own search. The
issue was that I had deleted the record ok, but just a few lines further down I
had referenced one of the fields of the deleted record... (only idiots do that!

I am not the first person to ask: supports "struts and springs" *how*? A
CALayer has no autoresizingMask. Surely ei

Of course I now have to ask if I *were* doing it .. what's the issue? Is it
that autorelease doesn't do anything so the CF type never gets the CFRelease()
call it would do f
If you are writing dual-mode code, can't you just wrap the
CFDictionaryCreateMutable() call with CFMakeCollectable()?

Essentially, yes. The primary design idea behind MVC is that there should be

It's definitely not code, Joanna. That's what the poster asked for, though.

Hallo everyone
Let's assume I have a custom NSView that will use to custom NSCell instances to
render its contents.
Now, if "drawRect:" is called on the NSView, I get the dirty rect that needs to
be redrawn.
The NSCell class on the other hands uses:

I need to construct a specialized keyboard (the software kind) for an iPad app
I am working on (using the SDKs and other tools that are presently available to
