Answer 1

Several options:

• (the right way) Use NSUserDefaults as drafted in this tutorial
• (simple but custom solution) Use a custom plist-file included within your application bundle as drafted in this tutorial
• (bit bloated for such simple case) Use CoreData for persitant storage of your objects / data
