Hi,
I want a generic animated split view. So I had a rummage online, and couldn't
find anyone who had prepared the wheel for me. Consequently I set out to create
my own. I soon found that overriding setPosition:ofDividerAtIndex: and make it
work correctly for split views with more than two vie
Hi,
I am planning to use the NSUserDefaultsController and KVO in Application
preferences implementation as a separate framework.
Question is: My application has many frameworks and Plugins and has to

Thanks Steve. For completeness - what's the proper way to perform the
cleanup? Should another static method be created that releases the singleton
instance when the app is closed? i.e.
+ (void)releaseSharedInterface
{
[sharedInstance release];
sharedInsance = nil;
}

It's not exactly deprecated. In the .h it say
Why do you need to do any explicit cleanup on app termination? App memory
disappears (poof!) so it's not like you're leaking anything. Is your class
holding onto some state that must be written out to disk, for example?

That's because a .h file is the HEADER.

I'll caution you as written that singleton is not be thread safe. Often you
don't care, because you only have one thread or because creating 2 webservice

Your archive includes an instance of "DataObject", but the process doing the

Just to add another two cents on the unreliability of pings for determining

etc. some wi-fi providers will respond to a ping of anything, so it will

Perform the second transform after the first animation completes in a
separate animation block. You can start the second animation block
from the first animation block's completion block.

Yep, that's true. I was going for the simple case since, unless you
specifically plan to reference the singleton from multiple threads, you don't
need to do anything more fancy.

I know there has to be a way of taking an image of size say 128X128
and drawing it in to a rectangle of say size 256X512
without loosing the aspect ratio of the original image.
However The following code DOES NOT DO THIS
NSImage * screenImage = [[NSImage a
-drawInRect draws the image into the destination rectangle, stretching or
shrinking as necessary to get it to fit. If you want to preserve the aspect
ratio, you'll have to generate a scaled rectangle with the image's aspect
ratio. That's just simple math.
