UserDefault with NSMutableArray ..

    In AppDelegate.h file just declare variable...

    

    NSUserDefaults  *userDefaults;

    NSMutableArray *yourArray;

    after...

    

    In AppDelegate.m Fille in applicationDidFinishLonching: Method

    

    userDefaults = [NSUserDefaults standardUserDefaults];

    NSData *dataRepresentingtblArrayForSearch = [userDefaults objectForKey:@"yourArray"];

    if (dataRepresentingtblArrayForSearch != nil) {

        NSArray *oldSavedArray = [NSKeyedUnarchiver unarchiveObjectWithData:dataRepresentingtblArrayForSearch];

        if (oldSavedArray != nil)

            yourArray = [[NSMutableArray alloc] initWithArray:oldSavedArray];

        else

            yourArray = [[NSMutableArray alloc] init];

    } else {

        yourArray = [[NSMutableArray alloc] init];

    }

    [yourArray retain];

    after that when you want to insert Data in this UserDefaults Use Bellow Code...

    

    [appDelegate.yourArray addObject:yourDataString];///set your value or anything which you want to store here...

    NSData *data=[NSKeyedArchiver archivedDataWithRootObject:appDelegate.yourArray];

    [appDelegate.userDefaults setObject:data forKey:@"yourArray"];

    [appDelegate.userDefaults synchronize];

And when you want to retrive data just retrive like bellow..

 i hope this help you...
