Okay guys, please help me with this simple question. I have a
checkbox. Once the checkbox is clicked, it stores the state in the
NSUserDefaults, and performs the action. However once the user quits
and opens the application again, the application will remember the
state of the checkbox. But will it still perfrom the action? I
searched for this everywhere and can't find an answer, please help!
Your question is meaningless; in 1969 NSUserDefaults hadn't been written
or even dreamt of. (Kidding... but you should reset your system clock;
that December 31, 1969 stuff happens to me whenever I have to push the
reset button on my TiBook...)
The real answer to your question is, I think, that you shouldn't rely on
the UI to maintain your application's state or direct what your app
does. Those are "model" or perhaps "controller" functions; the state of
a checkbox is part of the "view". The Vermont Recipes tutorials,
available at www.stepwise.com, provide a very clear example of how to
maintain a strict separation between the application's internal state
( model ) and its user interface (view).
