Thanks Nick!!
I got it that pcap will be used to capture packets. What will be achieved
using IOKit?
My other queries are like:

what application they belong to, , what particular document or tab (in case

Follow-up to my own question:
I decided that since the year and month derived properties were only there for
fetch requests, the correct thing to do is to get rid of them and instead use
predicates that look for the corresponding date ranges. That works just as
well, and avoids the derived prop

No, no, and no. Short of hacking

has the following method, which is defined/declared like this: ( I have

Hi
Could we customize the UITableView section header title color
programatically other than default one in a grouped table view ?
Thank you

You can provide a custom header view for each section through the
tableView's delegate. You can do whatever you want within that view.

A followup: One of my puzzlements was that the local folder "Archive" returned
NO from [folder exists], when my customer swore that an "Archive" folder was
there. I pressed him; the folder in place was named "Archives". So that was a
red herring.
I still am unable to insert a new folder under 1

For the category case, you can set the environment variable

I have a series of objects created periodically in my code which show no roots
under the GC Monitor in instruments, yet stubbornly refuse to be garbage
collected. I've tried forcing garbage collection and also clearing the stack in
various spots with objc_clear_stack(OBJC_CLEAR_RESIDENT_STACK).
Maybe I'm missing some things here, but hey; that's what I come to the
list for.
I'm not fully understanding the need for NSController's and/or what
they do.
Say I have an NSObject subclass:

BOOL boolProp;

I wanted to add that my problem in the second part of my question has
been solved. The only reason it wasn't working was that graphView is
actually a CALayer, and doesn't automatically call -willChange and -
didChange. Doing that solves the issue.
However, my question becomes more strange, a

If you see how "Touch Methods" is indented with respect to "Animation Methods",
it would seem to indicate that you're missing a closing brace in your
