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?
