Hi,
I'm developing an application for iPhone where the persistence is
managed with CoreData. I've introduced a singleton to initialize and
manage the NSManagedObjectContext, this is how I've defined the
singleton:
static Persistence *singletonPersistence = nil;
@implementation Persistence

There's a section in the Build Settings entitled "Data Model Compiler (MOMC) –
Warnings". Should find everything you want there.

Wonderful. Now I am going to have to change my tutorial. It looks like I am
going to have to investigate just what is available in the IDE.

Nick,
I'm using [NSView setNeedsDisplayInRect: r] and [NSView drawRect: r], so I'm
not explicitly flushing and that's not goofing things up. Beam-sync is related
to flushing, I think. I don't know how to turn it on or off programmatically
and it does not appear in QuartzDebug -- I think it wa

You might be able to do that, its worth a shot at least. You would create a
masking layer that is large enough to obscure all of your content

Hi all,
So for some days now I've been trying to make a custom NSActionCell that
works in an NSTableView that in turn uses Cocoa Bindings.
Starting from mmalc's ClockControl example, I now have it working for
simple cases.
Basically, I'm trying to implement a cell version of NSColorWell.

Never call -drawRect: directly. It is a Template Methods i.e. "Don't call us;
we'll call you." (Note: there might be some exceptions that prove the rule.)
As of Leopard and possibly sooner, individual dirty rectangles are available
through the - getRectsBeingDrawn:count: method if you use it w
It works:

Hi Cocoa developers,
I have a small application that consists of a NSTabView, in which all tabs
contain a single
custom NSView. That custom view is layer-backed (setWantsLayer:YES in
awakeFromNib).
So far, the view layer doesn't draw anything, and the NSView drawRect method
fills its content

Folks;
Thanks for the thoughts on this matter!
I think Matt raises an great point about hijacking on subsequent launches.
Personally I'm mistrustful of installers..
why does a simple application need to go mucking around on my system?
why is this application different than all th

Why? What are you trying to achieve?
I doubt it though! AFAIK you can only have a remote console (i.e.
screen sharing) so the app isn't running in the VNC session, it's
running normally on the host computer.

Because there are some things, such as WebKit plugins, Dashboard widgets, etc.
that cannot be used without installing them somewhere outside of the
application bundle.

Sorry I created the wrong impression there.
Of course I understand that there are 'things to be done' but Joe Consumer
doesn't necessarily know this...
Furthermore the installer don't make it clear what these things are nor why
they should have to be installed now

Eric is completely right but I'm wondering if the OP is saying what he

That's what I thought.
Why? So we can limit certain functionality over a remote connection. We do this
for Terminal Services connections on Windows and I was asked about doing it for
Mac.

You might try checking for any telltale running processes, or checking the
output of lsof -i for any open sockets that are indicative of a VNC or ARD
connection. That might have to run sudo'd as root.

Hi Gaurav,
Welcome to Cocoa development! It's fun, and very rewarding. Regarding your
question, you really will want to avoid taking Windows design patterns (for
both development and user experience) into a Mac app. Not only is what
you're trying to accomplish not possible, but it's a really bad u

#define's are basically a simple find and replace, so if you do:
#define IsDemo NO;
and then do:

It's going to become:

See the problem? You've got a semicolon in there. Generally, you don't end a

Take the ';' off the end of the #define, the replaced text is everything to the
end of the line, remember #define is just a text expansion, so with this

Leave out the semi-colon. #define is a macro, the complete text is simply
substituted for the name before compilation even starts, so you have the
equivalent of if(NO;){...} which is invalid syntax.
Thanks! I can't believe I missed that. Its 1:35am here and its been a long day.
