Local Notification Issue? - iphone

Question

I am new in iPhone application development. I am doing alarm application. In this application I am using local notification. I am calling notification method in done button action. Now I clicked done button means notification fired correctly. Then again clicked mean also fired, again and again press means working wrongly, but I am used notification fire date time same time. In this time completed means again user click done button means again triggered notification.
I want to fire that particular time. Can you please help me.
Here I am using this source code.
-(IBAction)doneButton
{
[self scheduledNotification];
}
-(void)scheduledNotification
{
Resource *resourceLoader = [[Resource alloc] init];
NSDictionary *prefDic = [resourceLoader getPlistDataAsDictionary:#"preference"];
if ([#"ON" isEqualToString:[prefDic objectForKey:#"alarm"]])
{
[[UIApplication sharedApplication] cancelAllLocalNotifications];
Class cls = NSClassFromString(#"UILocalNotification");
if (cls != nil)
{
NSString *musicName;
//NSDate *selectedDateTime = [[NSDate alloc]init];
selectedDateTime = [prefDic objectForKey:#"alarmtime"];
NSLog(#"saravanan periyasamy %#", selectedDateTime);
musicName = [NSString stringWithFormat:#"%#%#",[prefDic objectForKey:#"alarmmusic"],#".wav" ];
NSLog(#"musicname %#", musicName);
NSLog(#"saravanan periyasamy123 %#", selectedDateTime);
UILocalNotification *notif = [[cls alloc] init];
notif.fireDate = selectedDateTime; /* time for fireDate*/
NSLog(#"selectedtime %#",selectedDateTime);
notif.timeZone = [NSTimeZone systemTimeZone];
notif.alertBody = #"Alarm";
notif.alertAction = #"Show me";
notif.repeatInterval = 0;
notif.soundName = musicName;
notif.applicationIconBadgeNumber = 1;
NSDictionary *userDict = [NSDictionary dictionaryWithObject:#"saravanan"
forKey:kRemindMeNotificationDataKey];
notif.userInfo = userDict;
[[UIApplication sharedApplication] scheduleLocalNotification:notif];
[notif release];
}
}
}
AppDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
Class cls = NSClassFromString(#"UILocalNotification");
if (cls) {
UILocalNotification *notification = [launchOptions objectForKey:
UIApplicationLaunchOptionsLocalNotificationKey];
if (notification) {
NSString *reminderText = [notification.userInfo
objectForKey:kRemindMeNotificationDataKey];
//[self.viewController showReminder:reminderText];
[self.settingViewController showReminder1:reminderText];
}
}
application.applicationIconBadgeNumber = 0;
return YES;
}
- (void)applicationWillEnterForeground:(UIApplication *)application {
application.applicationIconBadgeNumber = 0;
}
- (void)application:(UIApplication *)application
didReceiveLocalNotification:(UILocalNotification *)notification {
application.applicationIconBadgeNumber = 0;
NSString *reminderText = [notification.userInfo
objectForKey:kRemindMeNotificationDataKey];
//[self.viewController showReminder:reminderText];
[self.settingViewController showReminder1:reminderText];
}

hi i not understand what your question but here i post my one example code for LocalNotification just compare it or use this example....
here when user click done button then call "btnGo_Clicked" method
-(IBAction)btnGo_Clicked:(id)sender{
NSLog(#"\n ----------->>Go Clicked");
Class cls = NSClassFromString(#"UILocalNotification");
if (cls != nil) {
NSString *kRemindMeNotificationDataKey = #"kRemindMeNotificationDataKey";
NSDateComponents *dc = [[NSCalendar currentCalendar] components:NSDayCalendarUnit|NSMonthCalendarUnit|NSYearCalendarUnit|NSHourCalendarUnit|NSMinuteCalendarUnit|NSSecondCalendarUnit|NSQuarterCalendarUnit fromDate:[exdatePicker date]];
[dc setDay:dc.day - 1];
NSDate *noticeDate = [[NSCalendar currentCalendar] dateFromComponents:dc];
NSDateFormatter* dateFormatterstring = [[NSDateFormatter alloc] init];
[dateFormatterstring setDateFormat:#"dd-MM-yyyy hh:mm:ss a"];
NSString *dateString = [dateFormatterstring stringFromDate:noticeDate];
txtExpirayDate.text = dateString;
UILocalNotification *notification = [[cls alloc] init];
notification.fireDate = noticeDate;
notification.timeZone = [NSTimeZone defaultTimeZone];
notification.alertBody = [NSString stringWithFormat:#"%# your Licence Expiry Date is Tommorow",txtLicence.text];
notification.alertAction = #"Show me";
notification.soundName = UILocalNotificationDefaultSoundName;
notification.applicationIconBadgeNumber = 1;
NSDictionary *userDict = [NSDictionary dictionaryWithObject:txtLicence.text forKey:kRemindMeNotificationDataKey];
notification.userInfo = userDict;
[[UIApplication sharedApplication] scheduleLocalNotification:notification];
[notification release];
}
exdatePicker.hidden=YES;
}
do some changes and you got your output
i hope this answer help you...

Remove this line if you want multiple press on button.
[[UIApplication sharedApplication] cancelAllLocalNotifications];
because its removing your all previous notifications.
