You can do it this way: 

if (![[NSUserDefaults standardUserDefaults] boolForKey:@"HasLaunchedOnce"]) {
   //first launch
   //show your alert
   [[NSUserDefaults standardUserDefaults] setBool:YES forKey:@"HasLaunchedOnce"];
   [[NSUserDefaults standardUserDefaults] synchronize];
}
else
{
    // app already launched
}
