Help with local notifications! - iphone

Question

I tried a verity of blogs but from some reason it doesn't fire!
Can it be because I don't ask permission? Am I suppose to ask the user for local? I understand from apple's documentation that I don't.
This is my singelton class (Checked it is called - with a breakpoint)
//
// «FILENAME»
// «PROJECTNAME»
//
// Created by «FULLUSERNAME» on «DATE».
// Copyright «YEAR» «ORGANIZATIONNAME». All rights reserved.

#import "NotifierSingelton.h"
static NotifierSingelton* _instance;
#implementation NotifierSingelton
+ (NotifierSingelton*)sharedInstance
{
#synchronized(self) {
if (_instance == nil) {
// iOS 4 compatibility check
Class notificationClass = NSClassFromString(#"UILocalNotification");
if(notificationClass == nil)
{
_instance = nil;
}
else
{
_instance = [[super allocWithZone:NULL] init];
}
// Allocate/initialize any member variables of the singleton class her
// example
//_instance.member = #"";
}
}
return _instance;
}
- (void) scheduleNotificationOn:(NSDate*) fireDate
text:(NSString*) alertText
action:(NSString*) alertAction
sound:(NSString*) soundfileName
launchImage:(NSString*) launchImage
andInfo:(NSDictionary*) userInfo
{
UILocalNotification *localNotification = [[UILocalNotification alloc] init];
localNotification.fireDate = fireDate;
localNotification.timeZone = [NSTimeZone defaultTimeZone];
localNotification.alertBody = alertText;
localNotification.alertAction = alertAction;
if(soundfileName == nil)
{
localNotification.soundName = UILocalNotificationDefaultSoundName;
}
else
{
localNotification.soundName = soundfileName;
}
localNotification.alertLaunchImage = launchImage;
//self.badgeCount ++;
localNotification.applicationIconBadgeNumber = 1;
localNotification.userInfo = userInfo;
// Schedule it with the app
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
[localNotification release];
}

I don't really see anything wrong with your code. Make sure your firedate is not null. Here is working code form one of my apps:
notif = [[UILocalNotification alloc] init];
NSDateFormatter *df = [[NSDateFormatter alloc] init];
[df setDateFormat:#"yyyy-MM-dd HH:mm:ss"];
NSDate *raceDate = [df dateFromString:[raceDates objectAtIndex:i]];
notif.fireDate = raceDate;
notif.timeZone = [NSTimeZone timeZoneWithName:#"WAT"];
notif.alertBody = NSLocalizedString(#"NotificationBody", #"");
notif.alertAction = NSLocalizedString(#"NotificationButton", #"");
notif.soundName = #"push.aif";
[[UIApplication sharedApplication] scheduleLocalNotification:notif];
[notif release];
Also, I'm not sure if it's required but your app may need to be multi-tasking enabled.
