Save a BOOL value using NSUserDefaults which corresponds to whether it is the application's first launch. If you find the boolean to be YES (or don't find the value), display the alert and set the value to NO.

3 simple lines 

-(BOOL)application:(UIApplication *)application … {
    if(![[[NSUserDefaults standardUserDefaults] objectForKey:@"NOT_FIRST_TIME"] boolValue])
    {
        [[[[UIAlertView alloc] initWithTitle:nil message:@"message" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil, nil] autorelease] show];
        [[NSUserDefaults standardUserDefaults] setObject:[NSNumber numberWithBool:YES] forKey:@"NOT_FIRST_TIME"];
    }
}

BOOL foo = [[NSUserDefaults standardUserDefaults]boolForKey:@"previouslyLaunched"];
if (!foo) 
{
    NSLog(@"FirstLaunch");
    [[NSUserDefaults standardUserDefaults]setBool:YES forKey:@"previouslyLaunched"];
}

Edit: What Akshay said earlier, with some code.

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];

    if([defaults objectForKey:@"FirstTime"] == nil) 
    {
      //your alert message  
    }  
     [defaults setObject:@"firsttime" forKey:@"FirstTime"];

You will probably need to store some data on first run of the application (like current date). Every time the application starts you will check for this data and if it doesn't exist store it and display the popup.
