i got following code which contains my localNotification:
-(void)scheduleNotification{
if (self.shouldRemind && [self.dueDate compare:[NSDate date]] != NSOrderedAscending){
UILocalNotification *localNotification = [UILocalNotification new];
localNotification.fireDate = self.dueDate;
localNotification.timeZone = [NSTimeZone defaultTimeZone];
localNotification.alertBody = self.text;
localNotification.soundName = UILocalNotificationDefaultSoundName;
localNotification.userInfo = [NSDictionary dictionaryWithObject:[NSNumber numberWithInt:self.itemId] forKey:#"ItemId"];
NSLog(#"Scheduled notification %# for itemId %d", localNotification, self.itemId);
}
}
My output in NSLog says following:
2013-07-28 15:39:48.684 JuneChecklist[2271:907] Scheduled notification {fire date = воскресенье, 28 июля 2013 г., 15:40:33 Московское стандартное время, time zone = Europe/Moscow (GMT+04:00) offset 14400, repeat interval = 0, repeat count = UILocalNotificationInfiniteRepeatCount, next fire date = воскресенье, 28 июля 2013 г., 15:40:33 Московское стандартное время, user info = {
ItemId = 0;
}} for itemId 0
But it is not shown (i tried launch app on iPhone and Simulator). I wonder why it shown fireDate in NSLog perfectly, but there is no notification when i wait for that time.
Any advice would be appreciated.
But where is [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];?
I am making an iPhone app, which has a requirement of Local Notifications.
In local notifications there is repeatInterval property where we can put the unit repeat intervals for mintute, hour, day,week,year, etc.
I want that repeat interval should be 4 hours.
So every 4 hours the local notification comes.
I dont want the user to set seperate notifications for each.
I want the user to be able to set repeatInterval as 4 hours.
How do I do that?
Got the answer, it is as straight as it gets.
You cannot create custom repeat intervals.
You have to use on NSCalendarUnit's in-built Unit Time Intervals.
I tried all the above solutions and even tried other stuffs, but neither of them worked.
I have invested ample time in finding out that there is no way we can get it to work for custom time intervals.
The repeat interval is just an enum that has a bit-map constant, so there is no way to have custom repeatIntervals, just every minute, every second, every week, etc.
That being said, there is no reason your user should have to set each one. If you let them set two values in your user interface, something like "Frequency unit: Yearly/Monthly/Weekly/Hourly" and "Every ____ years/months/weeks/hours" then you can automatically generate the appropriate notifications by setting the appropriate fire date without a repeat.
UILocalNotification *locNot = [[UILocalNotification alloc] init];
NSDate *now = [NSDate date];
NSInterval interval;
switch( freqFlag ) { // Where freqFlag is NSHourCalendarUnit for example
case NSHourCalendarUnit:
interval = 60 * 60; // One hour in seconds
break;
case NSDayCalendarUnit:
interval = 24 * 60 * 60; // One day in seconds
break;
}
if( every == 1 ) {
locNot.fireDate = [NSDate dateWithTimeInterval: interval fromDate: now];
locNot.repeatInterval = freqFlag;
[[UIApplication sharedApplication] scheduleLocalNotification: locNot];
} else {
for( int i = 1; i <= repeatCountDesired; ++i ) {
locNot.fireDate = [NSDate dateWithTimeInterval: interval*i fromDate: now];
[[UIApplication sharedApplication] scheduleLocalNotification: locNot];
}
}
[locNot release];
I have one idea how to do this, i've implemented this in my project
First, create local notification with fire date (for example, every minute).
Next step - fill user info with unique id for this notification (if you want to remove it in future) and your custom period like this:
-(void) createLocalRepeatedNotificationWithId: (NSString*) Id
{
UILocalNotification *localNotification = [[UILocalNotification alloc] init];
NSTimeInterval your_custom_fire_interval = 60; // interval in seconds
NSDate *remindDate = [[NSDate date] dateByAddingTimeInterval:your_custom_fire_interval];
localNotification.fireDate = remindDate;
localNotification.userInfo = #{#"uid":Id, #"period": [NSNumber numberWithInteger:your_custom_fire_interval]};
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
}
After that, implement -(void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification in your AppDelegate:
Fetch your custom period from user info.
Change fire date for next period
Just add it into the sheluded notificatiots again!
NSInteger period = [[notification.userInfo objectForKey:#"period"] integerValue]; //1
NSTimeInterval t= 10 * period;
notification.fireDate =[[NSDate date] dateByAddingTimeInterval:t]; //2
[[UIApplication sharedApplication] scheduleLocalNotification:notification]; //3
if you want to remove this notification, do
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:#"id"]];
if ([uid isEqualToString:notification_id_to_remove])
{
//Cancelling local notification
[app cancelLocalNotification:oneEvent];
break;
}
}
Very important!
-(void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification do not called, when you at background. So, you must setup long-running background task, where you will create notification again.

You can set any time interval you want, if you set up separate notifications for each time you want a notification to fire. You then have to manage them, and if you are not an app that is at present allowed to run in the background, you'll have to refresh them by having the user run your app to do so. Having accomplished this, I can tell you it is a major PITA.

I want use iPhone calendar add Event.
I try ti.com.calendar module from github but in this module only save startTime EndTime, Title and details.
but, not use allDay repeat or not reminder.
How i use this. in calendar?
I also user notification for reminder. but, after delete event. the notification is not delete.
any suggestion is appreciated

I am making the application that has needs to set the notification , thankfully i was able t set the local notification but i dont know how to delete the notification which is set by this application(my aplicaton ).The xcode does provide functionality of delete with removeAllNotifications but you cannot remove the selected notifications set by the application
You can call [[UIApplication sharedApplication] cancelLocalNotification:notification] to cancel a notification. Since local notifications conform to the NSCoding protocol, they can be stored and retrieved for later canceling.
I know this post is old but hope this solution helps someone
NSArray *notificationArray = [[UIApplication sharedApplication] scheduledLocalNotifications];
for(UILocalNotification *notification in notificationArray){
if ([notification.alertBody isEqualToString:#"your alert body"] && (notification.fireDate == your alert date time)) {
// delete this notification
[[UIApplication sharedApplication] cancelLocalNotification:notification] ;
}
}
I am comparing the alert body and date time just to make sure that i am deleting the right notification since there are chances where two or more notifications can have the same alert body or time.
