Can you give us so more details? For example: What will the app do?
Your description is very strange, lol.
But indeed, you should create a normal cocoa app that do the stuff you
want to do (UI + the real stuff),
and a little daemon that checks every X minutes if the other app is
running:
yes: ok, continue
no: start app (log message? App was stopped)

Could you split your app in two?
One would be a daemon that runs all times, the second a gui-frontend
for the deamon.
The problem seems to be that no one here can think of an app that
has a gui that no one ever looks at. Why a gui at all if no one
looks at it anyway?

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"

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.

1- How do you ensure only one instance of your app is running?
How do
you
detect if it stops responding? Can you restart it using
something like a
watchdog? And how would you go about implementing it?
The system already does this for you. Unless you're not writing a
regular application (say, a daemon or something), or you only
want one
instance regardless of how many people are logged in on the
machine
(say, using Fast User Switching). If you need to ask this
question,
you're probably not in either of these scenarios, so don't worry
about
it.
Actually, I'm writing a non regular application, and it's for a
controlled
environment. No users will be using the system, it should be
completely
automated and recover from errors. All I need is to make sure my
app is
running at all times. Would a simple cronjob check do the trick?
The only
thing I dont know how to do at the moment is to check if the app
is not
responding, and force quit it from an external script/app
2- Is there a way to launch applications like iTunes from cocoa
without
the
need to use AppleScript?
Look at the NSWorkspace documentation. iTunes's bundle
identifier is
com.apple.iTunes, but in general you can look at any app bundle's
Info.plist file to get its bundle identifier (the
CFBundleIdentifier
key).
Thanks, I did and it did the trick. One question though, it seems
the call
returns before the app is launched, what's the best way to detect
when the
app is launched? I heard there's something called notification
center or
so.
Is there a way to view all notifications being sent on my Mac?
