Hi,
I've been looking into creating a singleton class to manage some
objects that I have that I'd like to be globally available. I've been
reading through
http://www.cocoadev.com/index.pl?SingletonDesignPattern and all looks
well except I now have the following question ...
I'd like my singleton to observe the NSWorkspace notifications
applicationDidLaunch and applicationDidTerminate. I can setup the
observations in the init method, but how to I go about removing them ?
You would normally do in the dealloc method, but it seems you're not
meant to override dealloc in a singleton ? Would it suffice to put
them in the overridden release method ? If so, does this get called
automatically when I close the application ?
If I can't remove the notifications, I could end up with the
notification centre try to foward them to an object that no longer
exists.
Thanks
-Mic
