i want my alarm to be repeat every day at selected time with snooze functionality in iPhone

Question

i wanted to have repetition functionality in my Alarm clock app, in which i am unable to do.Can anyone help me out in any way.. like psuedo code or telling how to do, or some tutorial etc.

One more thing my Alarm is not invoking at correct time, it always delays by some time sometimes by 50 sec, lol. what should be done for that.

Here is my code what i have done till now...

@implementation The420DudeAppDelegate

@synthesize window;
@synthesize viewController,soundFlag;

NSString *kRemindMeNotificationDataKey = @"kRemindMeNotificationDataKey";

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    
    soundFlag = 0;

    Class cls = NSClassFromString(@"UILocalNotification");
    if (cls) {
        UILocalNotification *notification = [launchOptions objectForKey:
                                             UIApplicationLaunchOptionsLocalNotificationKey];

        if (notification) {
            NSString *reminderText = [notification.userInfo 
                                      objectForKey:kRemindMeNotificationDataKey];
            [viewController showReminder:reminderText];
        }
    }

    application.applicationIconBadgeNumber = 0;

    [window addSubview:viewController.view];
    [self.window makeKeyAndVisible];

    return YES;
}

- (void)applicationWillEnterForeground:(UIApplication *)application {
    application.applicationIconBadgeNumber = 0;
    soundFlag = 1;
}

- (void)application:(UIApplication *)application 
didReceiveLocalNotification:(UILocalNotification *)notification {

    application.applicationIconBadgeNumber = 0;
    NSString *reminderText = [notification.userInfo
                              objectForKey:kRemindMeNotificationDataKey];
    [viewController showReminder:reminderText];
}

    [viewController release];
    [window release];
    [super dealloc];

use this code may be it's help to u...

EKEventStore *eventStore = [[EKEventStore alloc] init];

    EKEvent *event  = [EKEvent eventWithEventStore:eventStore];
    event.title     = @"EVENT TITLE";

    NSDateFormatter* df = [[NSDateFormatter alloc] init];
    [df setDateFormat:@"MM/dd/yyyy"];
     event.startDate = [df dateFromString:@"your selected date"];


    NSLog(@"start date is %@",event.startDate);
    event.endDate   = [[NSDate alloc] initWithTimeInterval:600 sinceDate:event.startDate];
    //NSLog(@"end date %@",event.endDate);

    [event setCalendar:[eventStore defaultCalendarForNewEvents]];
    //NSLog(@"events are %@",event);
    //NSLog(@"events are %@",eventStore);
    NSError *err;
    [eventStore saveEvent:event span:EKSpanThisEvent error:&err];

it show alarm for set specific date and time import EventKit framework
