When does a Prefs file get created by the NSUserDefaults defaults system?

Hi All,

I'm having trouble with my application crashing when there has been a
Preferences file created.  In trying to understand how things are
working and how they are supposed to work, I find that the following
code doesn't create a Preferences file, even on quitting the
application.

#import "test.h"


@implementation test
+ (void)initialize
{
        //This doesn't seem to work.
        NSUserDefaults *defaults = [NSUserDefaults
standardUserDefaults];
        NSMutableDictionary *appDefs = [NSMutableDictionary dictionary];

        [appDefs setObject:@"NO" forKey:@"First Setting"];
        [appDefs setObject:@"YES" forKey:@"Second Setting"];
        [appDefs setObject:@"SNR" forKey:@"Third Setting"];

        [defaults registerDefaults:appDefs];
                                       `
}

@end

I had thought that it was supposed to set these values as the default
preferences, but I guess I'm wrong.  Later in the program when I write
changes to say the "First Setting" in the defaults database, a
Preferences file is created, and it contains that value, but not the
others.

How is this supposed to work?  Any ideas what I'm doing wrong?

Thanks,

Rob
