Hi, I'm hoping someone may have encountered something like this

How about setting a conditional breakpoint on [NSDictionary
setObject:forKey] with the condition object == nil?
Also, set a breakpoint on objc_exception_throw
Cool - haven't used conditional breakpoints before, and didn't realize
about objc_exception_throw...
That gives me completely different information, but much more useful:

I have an Employee entity with the attribute userInfo, which is a binary data

With time, as the user uses the app, garbage will pile up (albeit gradually)
in these dictionaries that are associated with the employees. And by garbage,

Seems to me that the source of the problem is the mixing of transient
and persistent key-value pairs within the same dictionary. If you
store the transient pairs in a dictionary of their own, that whole
dictionary could be transient.
It's not like that. I don't decide beforehand what is

Hi,
I'm trying to print a really large image into 'N' pages. So I over-rode
'knowsPageRange' and 'rectForPage'. Since I was able to successfully draw on
a single page, my rectForPage function returns the entire 'print view frame'
itself, and I draw a sub-image in this frame. My understanding is
Is it possible to add an encoding to CoCoa?
I have some text data from a legacy system which is ASCII for 0-127, but
128-255 is unique to the system. I'd like to load it into a text view
and just have it work.
What options do I have?

Well, certainly one way would be to preprocess the text buffer,
converting the custom characters into a standard encoding like UTF-8,
then passing the processed buffer into +[NSString
stringWithUTF8String:]. At that point it would just work since it's
in a known encoding.

Because you're translating from a decimal representation to a binary one,
