Stateful iPhone apps should be really easy. Like marking inheriting from a stateful class, mark up the members and calling a single method. Like this library.

Usage

1. Inherit from one of the following classes: StatefulObject, StatefulViewController or StatefulTableViewController, instead of NSObject, UIViewController or UITableViewController.
2. Change your application delegate to inherit from StatefulAppDelegate
3. In applicationDidFinishLaunching:, call the loadStateForVersion:timeoutInSeconds: function.

if ([self loadStateForVersion:1 timeoutInSeconds:0]) // if timeoutInSeconds is zero, never time out the state
{
}

# Name all members you want to save with the prefix "stateful".

1. Profit!
