Multiple instances of an app open?
-
Is it possible to open multiple instances of a Cocoa app?
I know you are going to have something to say about this. The app is
a windows app, that I've ported. They've done it in such a way that
if they wanted to make it multiple document, it would have to be
rebuilt from the ground up. Tons of global variables for just about
everything. Even stuff that should be passed on the stack is made
global, for no reason I can see.
So there is no way this app can be made multiple document based.
Is there any way multiple instances of the app can be opened then? I
know this is wrong and bad, but I'd just like to know. I'd like to do
it in a graceful way for the user, not ask them to duplicate the app
in the Finder :)

I've noticed that if you launch an application from the command line,
it will not "merge up" with an already running instance. Try it for
yourself and you will get as many instances as you desire.
Based on that fact, if I was trying to commit the UI crime you are
trying to commit :) , I would probably look into making a wrapper app
bundle that, upon being launched, manually invoked the executable of
the real application held inside of it, and immediately quit. This
should be enough to cause the Finder to repeatedly allow launches of
the app, though you might have some trouble if the user tried to fire
off two as fast as they can click...

LaunchServices has a kLSLaunchNewInstance flag you can pass in.

In that case, I'm sure glad I never had to try to do this, or else I
would have spent a lot of time barking up the wrong tree :) -
Pre-OS X, I heard of an app developer faced with a problem much like yours. Their solution was to embed basically the whole app into a DLL and then they could use CFM to instantiate as many as they needed, and it was fairly clean and all inside one process.
I think this sort of solution might still be applicable on OS X.

Why don't you use an MDI interface with your application that allows
multiple document windows. This will allow easier process management
and allow the user to be able to control document windows.

Reflected in NSWorkspace since 10.3: NSWorkspaceLaunchNewInstance

Nice. I made a user space application for this:

have fun and shoot yourself in the foot. ;-) But seriously, for some
single document apps this is great ;-)
