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];
`
}

[defaults synchronize]; // may be

@end

Do you have a CFBundleIdentifier key set in your Info.plist?
