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.

from the code below what "defaults" is. Have you tried substituting

I do something like the following in my application
[defaults setObject:@"some string" forKey:@"myKey"];
later after restarting the program, I do something like
NSString *myString;
myString = [defaults objectForKey:@"myKey"];
if (myString != nil)
{
// do something
}
else
NSLog(@"myKey is missing");
which logs "myKey is missing" every time. After reading the
documentation on User Defaults several times over I no grok. Is there
something I have to do in my application bundle before I can set
objects
in the Application domain, or am I missing something more basic? Where
is the User Defaults dictionary stored? Is there some way to inspect
it?
I'm an old NeXT developer from way back, but I'm having to learn a few
new tricks with Cocoa.
Cheers, Eric
