why should your app stops responding?
Do you want to detect time-outs (network-times, IO-timeouts, ...) or
will your app be crap and full with bugs?

The best way to ensure your daemon or agent is always running is
to have
it
run via launchd.
Start by reading the launchd man page and the "Daemons and
Agents" tech
note; these will give you an overview of how Mac OS X used
launchd to
manage
these types of on-demand and always-on services.
But my app is a "normal" Cocoa App, it's not a daemon or an agent.
It's still essentially an agent, just one that runs in the
foreground, not
the background.
You can use launchd to keep your app alive. That way you, don't
have to
worry about adding code to your application to do it, you just have
to
ensure the launchd property list is in the right place.
That will also make development of your application easier, because
your
application can run normally; you won't have to put a bunch of
extra code
into it to disable its keep-alive behavior during development.
Great, so I understand from what you're saying that I can launch a
GUI app
using launchd? I will look into it. Also, what if the application
stops
responding? Is that something that launchd can detect?
