Hi all,

I have run into a problem when using NSUserdefaults. That is, I did change
the value of NSUserDefaults ,but the next time I run my application, the
preferences is the old one. Followed is my code, could any one help me find
my problem? Thanks very much.

@interface MyObject : NSObject
{
   IBOutlet id myOutlet1;
   IBOutlet id myOutlet2;
   IBOutlet id myOutlet3;
   IBOutlet id myOutlet4;
NSUserDefaults * prefs;

}
- (IBAction)save:(id)sender;
@end

#import "MyObject.h"

@implementation MyObject

- (IBAction)save:(id)sender
{

       [prefs setObject:[myOutlet1 stringValue] forKey:@"FavBook"];

       [prefs setObject:[myOutlet1 stringValue] forKey:@"FavCity"];

       [prefs setObject:[myOutlet1 stringValue] forKey:@"FavColor"];

       [prefs setObject:[myOutlet1 stringValue] forKey:@"FavFood"];
}

- (id)init
{
   [super init];
   NSMutableDictionary * defaultPrefs = [NSMutableDictionary
dictionary];
   [defaultPrefs setObject:@"Learning Cocoa"
forKey:@"FavBook"];
   [defaultPrefs setObject:@"San Francisco"
forKey:@"FavCity"];
   [defaultPrefs setObject:@"Red"
forKey:@"FavColor"];
   [defaultPrefs setObject:@"Mexican" forKey:@"FavFood"];

   prefs = [[NSUserDefaults standardUserDefaults]
retain];
   [prefs
registerDefaults:defaultPrefs];
   return self;
}

- (void)dealloc
{
   [prefs release];
   [super dealloc];
}

- (void)awakeFromNib
{
   [myOutlet1 setStringValue:[prefs stringForKey:@"FavBook"]];
   [myOutlet2 setStringValue:[prefs stringForKey:@"FavCity"]];
   [myOutlet3 setStringValue:[prefs stringForKey:@"FavColor"]];
   [myOutlet4 setStringValue:[prefs stringForKey:@"FavFood"]];
}

@end

Yours sincerely
