Thanks Steve. For completeness - what's the proper way to perform the
cleanup? Should another static method be created that releases the singleton
instance when the app is closed? i.e.
+ (void)releaseSharedInterface
{
[sharedInstance release];
sharedInsance = nil;
}

Why do you need to do any explicit cleanup on app termination? App memory
disappears (poof!) so it's not like you're leaking anything. Is your class
holding onto some state that must be written out to disk, for example?

I'll caution you as written that singleton is not be thread safe. Often you
don't care, because you only have one thread or because creating 2 webservice
clients may not be a problem for you.

Yep, that's true. I was going for the simple case since, unless you
specifically plan to reference the singleton from multiple threads, you don't
need to do anything more fancy.

Thanks for all your answers, they make complete sense.
I have one more related question. I have developed a custom, stateful
WebServiceInterface object, which manages all connection requests made to an
XML-RPC server. Being stateful, I initialise this object when the app
launches and at the
How about providing a singleton class method? Then you just include
WebServiceInterface.h where needed. No need to have a global variable.
@implementation WebServiceInterface
...
+ (WebServiceInterface*) sharedInterface
{
static WebServiceInterface* sharedInstance = nil;

Thanks for your response Steve. I have considered using the
nsnotification service but what if you need to not only let another
object know when an event has occurred but you also need to send that
object some data? For example a user selects an option in a table -
the selection must be conveyed

A view controller controls a specific view hierarchy so it shouldn't be
reaching explicitly out to other view controllers to tell them to do something.
Depending on your specific situation, interested objects could register for
notifications when certain things change in the world, then one
