iPhone: UILocalNotification doesn't repeat the notification - iphone

Question

I am trying to use UILocalNotification in my project. I want my application to get notified every 5 seconds (non stop) in the background. I am trying the following code. It is notifying my application only for the first time after 5 seconds, after installed. I want it to be notified continuously every 5 seconds without stop. How can i achieve it?
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
// Override point for customization after application launch.
self.window.rootViewController = self.viewController;
[self.window makeKeyAndVisible];
// Initiating notification at app startup
[self InitiateLocalNotification];
return YES;
}
-(void) InitiateLocalNotification
{
NSDate *notificationDate = [NSDate dateWithTimeIntervalSinceNow:5];
UILocalNotification *notify = [ [UILocalNotification alloc] init ];
notify.fireDate = notificationDate;
//notify.applicationIconBadgeNumber = 1;
notify.soundName = UILocalNotificationDefaultSoundName;
notify.timeZone = [NSTimeZone defaultTimeZone];
//notify.alertBody = #"Local notification test";
//notify.repeatInterval = 1;
NSDictionary *infoDict = [NSDictionary dictionaryWithObject:#"notifiValue" forKey:#"notifiKey"];
notify.userInfo = infoDict;
// Schedule the notification
[[UIApplication sharedApplication] scheduleLocalNotification:notify];
[notify release];
}
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
{
}

I think, you need to register for the notification again if you receive any,
your code could be :
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{ // Override point for customization after application launch.
self.window.rootViewController = self.viewController;
[self.window makeKeyAndVisible];
// Initiating notification at app startup
[self InitiateLocalNotification];
return YES;
}
-(void) InitiateLocalNotification
{
NSDate *notificationDate = [NSDate dateWithTimeIntervalSinceNow:5];
UILocalNotification *notify = [ [UILocalNotification alloc] init ];
notify.fireDate = notificationDate;
//notify.applicationIconBadgeNumber = 1;
notify.soundName = UILocalNotificationDefaultSoundName;
notify.timeZone = [NSTimeZone defaultTimeZone];
//notify.alertBody = #"Local notification test";
//notify.repeatInterval = 1;
NSDictionary *infoDict = [NSDictionary dictionaryWithObject:#"notifiValue" forKey:#"notifiKey"]; notify.userInfo = infoDict;
// Schedule the notification
[[UIApplication sharedApplication] scheduleLocalNotification:notify];
[notify release];
}
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
{
// Need to register again
[self InitiateLocalNotification];
}

You are only calling
[self InitiateLocalNotification];
once, and therefore only scheduling one notification.
You must schedule each notification that you wish to receive (schedule notification 5 seconds from now, 10 seconds from now ... etc), since you don't have that kind of control over the repeat interval.
A solution would be to schedule the next one when you receive a notification, but that won't result in notifications scheduled exactly 5 seconds apart.
