Salutations,

The Versions store will do this automatically. It can detect when blocks of a
file have been duplicated and avoid storing those blocks on disk.

Further to earlier answers, bear in mind you've got no guarantee that file
extensions are correct, or even exist. Plus of course, you might have both .jpg
and .jpeg. You might well be better iterating through, finding the UTI of each
file, and working from that.

I am unable to find out as to why I am receiving this problem, I can verify
other parts of the code before it gets to the return and that the object I am
returning does in-fact work as I am able to NSLog it and see the description of

It kind of looks like foundCookieJar is an ivar, which means that "return
foundCookieJar" is really going to be "return self->foundCookieJar". Since you
set "self" to "nil", you're trying to dereference a NULL pointer, which is a
great way to crash your app.

Well, let's think about it. "Instance variables" are only accessible as long
as you have an instance, right? You can't have an instance variable without an
instance. So if you set "self" to nil... then you no longer have an instance.
Thus, you cannot access self's instance variables, because

No need to use grep... you can just:

I just came across a bit of an issue with the full screen mode in Lion: if you
have a view and use [[self window] windowController] to get at your window
controller, it will return nil in full screen mode. The window gets swapped out
with an NSToolbarFullScreenWindow, which doesn't have a window

Sorry - missed an important bit of info - this applies for a view that is in
the toolbar. So far as I am aware, it doesn't apply to views in your main
window (at least my views in my main window still appear to always return the
right thing).
