You set the default of a NSUserDefault. Set that default to FALSE.
Then on startup, check the value. If its FALSE - set it to TRUE and
you know its the first time. Here is some from-memory typed code:
NSMutableDictionary *dictionary = [[NSMutableDictionary alloc]
initWithCapacity: 10];
[dictionary setObject: [NSNumber numberWithBool:NO] forKey:
PIFirstRun];
[[NSUserDefaults standardUserDefaults] registerDefaults: dictionary];
[dictionary release];
if ([[NSUserDefaults standardUserDefaults] boolForKey:PIFirstRun] ==
YES)
{
[[NSUserDefaults standardUserDefaults] setBool:YES
forKey:PIFirstRun];
//first run
}

Can you please elaborate on this a bit more?
I am already using NSUserDefaults for my preferences values.
But I fail to see how this apply to determining if an Application is
launched for the very first time...
What do I do?
Check to see if an NSUserDefault item exists?
Thanks for the help...

So that I can set an integer variable once only at this moment...
What's the best way to do this?
Also, NSUserDefaults supports this basic capability. I'm just
wondering if all these defaults for your app are visible from the
settings application on the iPhone (it is too late and my brain is
fried); that would screw up this approach.
