Enable/disable a perticular UILocalNotification and set multiple notification once - objective-c

Question

NOTE: Need to know how to Set a number of alarm or notification in between two given dates regularly?
I have to create an app where,i have to enable/disable multiple UILocalnotification set in a tableview.'
If i choose a date i have to then set time on that perticular date and also need to set the notification before timePlay (5,10,15,20 min prior).
And End date: the date until when the notification plays regularly.
How to set all the notification for a perticular notification ID at once?
How to disable a perticular notification?
ALSO PLEASE TELL ME : CAN HOW CAN I SET UILOCALNOTIFICATION using database?
I have create a database having
Notification ID //unique id of notification
Notification Name //notification title
Time1 //can set five time the notification will show
Time2(optional)
Time3(optional)
Time4(optional)
Time5(optional)
Before timePlay//can show the notification before time of notification 1 to 5 above
Start Date // the date from which the notification start
End Date //the date when the notification stops.
i can set simple notification like this
// UILocalNotification properties:
// alertBody - the message displayed in the notification
// alertAction - if notification is displayed as an alert, this is the label of the action button, if not specified, "Launch" will be used
// soundName - the name of a sound file (AIFF, CAF or WAV) to be played when the notification appears, if not specified, no sound will be played. To use the default sound UILocalNotificationDefaultSoundName can be provided.
// userInfo - you can pass an NSDictionary object with additional data to be used by our app after the notification fires (optional)
// fireDate - an NSDate object specifying the date and time for the local notification to be fired (obligatory)
// timeZone - an NSTimeZone object. If specified, the fireDate is measured against the user's local time zone, if not against universal time
// repeatCalendar - the calendar (NSCalendar) the system should refer to when it reschedules a repeating notification
// repeatInterval - the calendar interval (NSCalendarUnit) at which to reschedule the notification, the default is 0, which means don't repeat
// alertLaunchImage - will be presented when your app is run or summoned from the background
// Create a new local notification
UILocalNotification *notif = [[UILocalNotification alloc] init];
notif.alertBody = #"Wake up! Its tuition time!";
notif.fireDate = [NSDate dateWithTimeIntervalSinceNow:60]; // 60 seconds
notif.soundName = UILocalNotificationDefaultSoundName;
notif.applicationIconBadgeNumber += 1;

Answer 1

Try scheduling which will enable the notification and use cancel which will be disable the notification:-
-(void)enableNotification
{
[self cancelAlarm]; //clear any previous alarms
UILocalNotification *alarm = [[UILocalNotification alloc] init];
alarm.alertBody = #"alert msg";
alarm.fireDate = [NSDate dateWithTimeInterval:alarmDuration sinceDate:startTime];
alarm.soundName = UILocalNotificationDefaultSoundName;
NSDictionary *userInfo = [NSDictionary dictionaryWithObject:self.name forKey:kTimerNameKey];
alarm.userInfo = userInfo;
[[UIApplication sharedApplication] scheduleLocalNotification:alarm];
}
-(void)disableNotification{
for (UILocalNotification *notification in [[[UIApplication sharedApplication] scheduledLocalNotifications] copy]){
NSDictionary *userInfo = notification.userInfo;
if ([self.name isEqualToString:[userInfo objectForKey:kTimerNameKey]]){
[[UIApplication sharedApplication] cancelLocalNotification:notification];
}
}

Answer 2

at time of notification schedule give a unique notification key in notification's userinfo and to cancel notification you can use below code as where
UIApplication *app = [UIApplication sharedApplication];
NSArray *eventArray = [app scheduledLocalNotifications];
for (int i=0; i<[eventArray count]; i++)
{
UILocalNotification* oneEvent = [eventArray objectAtIndex:i];
NSDictionary *userInfoCurrent = oneEvent.userInfo;
NSString *uid=[NSString stringWithFormat:#"%#",[userInfoCurrent valueForKey:#"uid"]];
if ([uid isEqualToString:uidtodelete])
{
//Cancelling local notification
[app cancelLocalNotification:oneEvent];
break;
}
}
