Re: NSUserDefauts - Am I Missing the Obvious?

This is true. I have no idea why.

When I created a variable for NSUserdefaults, I had the same problem.
As soon as I accessed [NSUserDefaults standardUserDefaults] directly,
it updated. Can anyone shed light on why this would be so?

Also, there are problems if you've defined the key to be of one type,
then try to read/write as another. I had a problem between arrays and
single objects. I had to delete the key, then re-write it as the new
type I wanted.
