Question

Is there an easy way to have an alert appear only the first time an app is launched, or will I have to do it manually by making a BOOL and having it set to FALSE after it’s run the first time?

Answer 1

Sounds easy enough…

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];

if(![defaults boolForKey:@"hasBeenLaunchedBefore"]) {
  //Show alert
  [defaults setBool:YES forKey:@"hasBeenLaunchedBefore"];
  [defaults synchronize];
}
