Hi Folks,

Hello All,
I'm working on MIDI set-up customization for my music app. I have a main
controller object, called Central_MIDI_Controller, that uses the VVMIDI
framework to detect MIDI ports, and handle low-level MIDI stuff. I have an
object called MIDIInstrument, which is a simple wrapper-type ob
MIDI_Controller
connected in IB.
From the MIDIInstrument init, I can run [[NSApp delegate] midiController] and
get the instance of Central_MIDI_Controller loaded in the nib. As I say, it
feels a bit hackish. Though it does work, and advice is still welcome.
cheers,
J.

single instance, and that it wouldn't have any effect on future instances.

Looking over the type of model I want to build for my music app, I realized
that perhaps Core Data would be a good way to manage it. The reason being that

channel, and an arbitrary number of "Articulations." The total se
This shouldn't be a difficult problem, but how do I make a NSPopUpButtonCell
load a list of numbers, and return the value of the number when selected?
Originally I used a ComboBox, with pre-programmed values from IB, but it
returned strings, not NSNumbers. This really should be simple, and maybe
ct for the NSArrayController to the desired object (in
my case, it was the "channel" key in the NSArrayController for my Core Data
model)
Not certain that this is right, but it works. Hope it saves someone else the
trouble later on.

Okay, so I'm back to trying to tackle this annoying unarchiving crash…
Just to recap the problem: I get a exc_bad_access crash when unarchiving
certain files from disk. The file is a keyed archive, which contains a fairly
complex custom object graph, with plenty of circular references (i.e.,

Sure, understood.

encoding/decoding it that works.
Thanks for your help, everybody.

I have a situation where I've created a subclass that overrides a number of
synthesized property accessors in its superclass. What I'm wondering is whether
the overridden methods will get called when using dot syntax, or if this will
just return the (inherited) synthesized properties?
So the "T
(operative word
being "method"), was never really explained! ;-)
Thanks again.

Hello All,
I'm finding that the first time I ask for a context menu (i.e., control-click
or two-finger tap) it takes several seconds to come up. After that it responds
normally. Has anybody seen this and, if so, do you recall what the problem was?
(It only happens on my laptop, not my desktop..
Ah, thanks for the tip. I'll take a loot at that tomorrow.

Hi All,
I'm using NSPointerArrays to store references for a complex object graph. The
nodes themselves are stored in an NSDictionary for archiving, and the pointer
arrays are just used to record the interconnectivity of the nodes (it's loopy
and complex, which has been causing problems with NSK
Hello All,
Has anyone had problems compiling drawkit on 10.8? I can't seem to build it. I

Hello All,
I've created a framework to pull together a bunch of code I'm using regularly.
When I include this framework in another project the project builds, and the
methods do appear to get called, but I get "instance method <…> not found"
warnings all over the place. The headers are all impo

I've run into a situation where I really need a deep copy of an object. I've
implemented this using Apple's recommended approach with
NSKeyedArchiver/Unarchiver, and it's nice, simple, and functional. But it's
also pretty darn slow -- as in a clear, subjectively apparent performance hit.
Has any
ing to the wholesale NSKeyedArchiver approach of grabbing the
entire object graph.
So, problem solved. If I ever feel inclined to discover a deeper fix I will,
but it won't be any time soon!
