I have searched for help on this issue but I am falling short of an answer. I am setting an event reminder with code. Using break points and stepping thru. I see the event time is correct. Below is how I set my reminder
EKEventStore *eventDB = [[[EKEventStore alloc] init]autorelease];
EKEvent *myEvent = [EKEvent eventWithEventStore:eventDB];
NSString * eventTitle = [NSString stringWithFormat:#"%# - %#",app.dealerBusinessName,serviceOrComments.text];
myEvent.title = eventTitle;
// "destinationDate" is the date I want to set the reminder for it is correct in debugger
//its format is 2011-06-03 15:45:58 +0000 which means (i would think) that the reminder
//should be set for 6/3/2011 3:45PM but its always 6 hours earlier (in this case at 9:45am
NSLog(#"value: %#",destinationDate);
myEvent.startDate = [[[NSDate alloc] initWithTimeInterval:0 sinceDate:destinationDate ]autorelease];
myEvent.endDate = [[[NSDate alloc] initWithTimeInterval:3600 sinceDate:myEvent.startDate]autorelease];
myEvent.allDay = NO;
myAlarmsArray = [[NSMutableArray alloc] init];
EKAlarm *alarm1 = [EKAlarm alarmWithRelativeOffset:-3600]; // 1 Hour
EKAlarm *alarm2 = [EKAlarm alarmWithRelativeOffset:-86400]; // 1 Day
[myAlarmsArray addObject:alarm1];
[myAlarmsArray addObject:alarm2];
myEvent.alarms = myAlarmsArray;
[myEvent setCalendar:[eventDB defaultCalendarForNewEvents]];
NSError *err;
[eventDB saveEvent:myEvent span:EKSpanThisEvent error:&err];
if (err == noErr) {
//no error, but do not show alert because we do that below.
}
Now im pretty sure I can just add 21,600 to the time but is that the correct way to do it? I am not understanding how NSDate works and its driving me nuts. Can someone explain to me what the correct way to do this is? Thanks!
I had a similar problem lately, it was really driving me nuts. You have to take your time zone into account (or the timezone your simulator/device are set to). NSDate represents always GMT time, NSCalendar the time within the time zone. So the time differences you are experiencing will exactly be the time difference between your time zone and GMT (your alarm gets triggered at 15:45 GMT).
Since I want my dates to be absolute, regardless of the time zone, I am setting all my NSCalendars to GMT - it works in my case, of course YMMV.

I want to add events to calendar with alarm. If any event time is at 9.00 then alarm must be set at 8.45 ,How to add alarm time using EKAlarm.
Thanks in advance.
i just found a description at techotopia For set time in alarm using Eventkit framework in ios 6 like:-
-(void)createReminder
{
EKReminder *reminder = [EKReminder
reminderWithEventStore:self.eventStore];
reminder.title = _reminderText.text;
reminder.calendar = [_eventStore defaultCalendarForNewReminders];
NSDate *date = [_myDatePicker date];
EKAlarm *alarm = [EKAlarm alarmWithAbsoluteDate:date];
[reminder addAlarm:alarm];
NSError *error = nil;
[_eventStore saveReminder:reminder commit:YES error:&error];
if (error)
NSLog(#"error = %#", error);
}
Hope its helps you :)
I am new in iPhone development.
There is a requirement in my application in which, there is a web service link which is below:
http://01s.in/webservices/sikhcalendar/getData.php?db_table=cal
so i want that the particular date which are shown in link, that date should be added in iCal which are add in my end in app. and it should generate an alert view on that particular day.
So, I am not getting how to add an event in iCal. Please give me some answer for this.
Thanks in advance.
adding a date in ical first you have to add the two framework in your code i.e.EventKit/EventKit.h, EventKitUI/EventKitUI.h and conforms the class to EKEventEditViewDelegate delegate and use the below method to add date in iCal
- (void)eventEditViewController:(EKEventEditViewController *)controller didCompleteWithAction:(EKEventEditViewAction)action
and i recommend you to go through this url and learn about these framework
Adding Event on the default calendar can be done using the following function
-(void)createEvent :(NSString *)eventTitle: (NSURL *)eventURL: (NSString *)eventNotes: (NSDate *)eventStartDate: (NSDate *)eventEndDate{
EKEventStore *eventStore = [[EKEventStore alloc] init];
EKEvent *event = [EKEvent eventWithEventStore:eventStore];
event.title = eventTitle;
event.URL = eventURL;
event.notes = eventNotes;
event.startDate = eventStartDate;
event.endDate = eventEndDate;
[event setCalendar:[eventStore defaultCalendarForNewEvents]];
EKAlarm *myAlarm = [EKAlarm alarmWithRelativeOffset:0];
[event addAlarm:myAlarm];
NSError *err;
BOOL success = [eventStore saveEvent:event span:EKSpanThisEvent error:&err];
NSLog(#"event created success if value = 1 : %d", success);}
Here eventStartDate would be the time when the alarm which you set gets executed, and you get a notification
Please take a look into the EventKit framwork and the Apple Documentation.
Everything is there :)

After goggling for 2 days i couldn't find any solution as if its clear to everyone (but me) !
I need the:
Alert.applicationIconBadgeNumber = x
to be updated in background each time the notification fires, I am repeating the notify by:
notif.repeatInterval = NSMinuteCalendarUnit
Repeating is working fine every 1 m. when the app goes in background, but the BadgeNumber dosent get updated, it takes the 1st updated date value only.
I am calling the scheduleNotification method by viewDidLoad
Here is my full code:
- (void)scheduleNotification {
UILocalNotification *notif;
notif = [[[UILocalNotification alloc] init] autorelease];
notif.timeZone = [NSTimeZone defaultTimeZone];
notif.fireDate = [[NSDate date] dateByAddingTimeInterval:5];
notif.repeatInterval = NSMinuteCalendarUnit;
NSInteger BadgeNumber = [self BadgeNumber];
NSInteger *BadgeNumberPointer = &BadgeNumber;
NSString *BadgeNumberString = [NSString stringWithFormat:#"%i", BadgeNumber];
notif.applicationIconBadgeNumber = *BadgeNumberPointer;
notif.alertBody = BadgeNumberString;
notif.alertAction = #"Hello";
[[UIApplication sharedApplication] scheduleLocalNotification:notif];
}
-(int)BadgeNumber{
NSDate *currentDateUpdate = [[NSDate alloc] init];
NSDateFormatter *formatter2 = [[NSDateFormatter alloc] init];
[formatter2 setDateFormat:#"dd"];
NSString *dateCheckUpdate = [formatter2 stringFromDate:currentDateUpdate];
NSInteger dateCheckUpdateInt = [[dateCheckUpdate substringWithRange:NSMakeRange(0, 2)] integerValue];
int BadgeNumber = dateCheckUpdateInt;
return BadgeNumber;
}
Kindly advice how to fix it,, thanking all of you.
Because the operating system copies the notification when scheduled, the data in the notification is not updated, therefore the application badge number doesn't change.
Maybe if you don't repeat the notification but generate your own new notification for each time interval it will give you the behavior you need. The only way I can think of generating notifications like that is to post a bunch of notifications in your scheduleNotification method, and then remember to delete the notifications when the user responds in the proper way. Since the OS only remembers the next chronologically scheduled 64 notifications, you could only schedule about an hour's worth. Since your badge number seems to be the current date, you could check the time and only bother with setting so many notifications if you're within an hour of midnight.
I don't understand what you are trying to accomplish by nagging the user so often, nor telling them the date in the badge number. Any app that bothered me so much or misused the badge number so would quickly get deleted from my iOS devices. Maybe rethinking what you are trying to accomplish may direct you to a better solution.
I know this is already answered, but you could use NSUserDefaults as a means of caching the badge count. Then in applicationIconBadgeNumber you can just use something like this:
notif.applicationIconBadgeNumber = ([NSUserDefaults standardUserDefaults] integerForKey:#"badgeCount"] + 1);
and then you could just reset it when the user responds accordingly.
This is driving me nuts so I hope someone can help an Objective-C noob figure this out. Here's the deal:
I'm developing an iPhone app using Titanium Appcelerator and I'm trying to create an add-on module in XCode that will allow me to send an event to the iPhone calendar. What I'd like to do is to calculate the date and time in terms of seconds since Jan 1, 2001 (GMT) and send it directly to calendar without having to mess with the string-to-date stuff that seems always to return the wrong time. To this point, I've not been able to get the integer into the event date fields, both of which are NSDate types.
Titanium takes arguments from Javascript and compiles it into object code, so I can call my "cal" object like this:
var startDate = 316367923;
var endDate = 316367923;
var results = cal.newEvent(startTime,endTime)
. . . and this is how the "cal" object receives that call:
-(BOOL)newEvent:(id)args {
id startDate = [args objectAtIndex:0];
id endDate = [args objectAtIndex:1];
...
What I'm hoping to do get these integers into the event object:
EKEventStore *eventDB = [[EKEventStore alloc] init];
EKEvent *theEvent = [EKEvent eventWithEventStore:eventDB];
...
theEvent.startDate = [[NSDate alloc] initWithTimeIntervalSinceReferenceDate: (int) startDate];
theEvent.endDate = [[NSDate alloc] initWithTimeIntervalSinceReferenceDate: (int) endDate];
This compiles with no errors but causes my app to bomb nonetheless, so I'm figuring I've got something missing in my understanding. Any idea of where I'm going wrong?
Thanks,
Mark
Quite probably 'args' is an NSArray, hence startDate and endDate are objects, not literals. You probably want to do something like:
theEvent.startDate = [[NSDate alloc] initWithTimeIntervalSinceReferenceDate:[startDate intValue]];
If e.g. startDate is an NSNumber. Otherwise, check out the Titanium docs to find out the type of numbers passed in.
This may not be the cause of your crash, but the initWithTimeIntervalSinceReferenceDate NSDate method is expecting an NSTimeInterval (defined as typedef double NSTimeInterval) not an integer.
i.e.: Its method signature is:
- (id)initWithTimeIntervalSinceReferenceDate:(NSTimeInterval)seconds
I'd bet startDate and endDate are being converted to NSNumber objects instead of ints. Therefore, try the following lines:
theEvent.startDate = [[NSDate alloc] initWithTimeIntervalSinceReferenceDate: (int) [startDate intValue]];
theEvent.endDate = [[NSDate alloc] initWithTimeIntervalSinceReferenceDate: (int) [endDate intValue]];
I doubt that your crash has anything to do with it but, you might be leaking. The lines:
theEvent.startDate = [[NSDate alloc] initWithTimeIntervalSinceReferenceDate: (int) startDate];
theEvent.endDate = [[NSDate alloc] initWithTimeIntervalSinceReferenceDate: (int) endDate];
assign an object with retain count 1, if the setter for startDate and EndDate takes ownership of them (I don't know if java will do that or not so I might be wrong) you must store them in a local variable before assigning them to theEvent, so that you can call release afterwards.
so it would look like this:
NSDate *sDate = [[NSDate alloc] initWithTimeIntervalSinceReferenceDate:[startDate intValue]];
theEvent.startDate = sDate;
[sDate release];
I have an app which saves text and the date from a UIDatePicker and then shows that note if you got back into that date in the UIDatePicker.
It works great! Only I have found that setting the UIDatePicker date to today stops CoreData working.
It's only when I run this setDate line does it stop core data from working. The app runs fine without crashing, it just doesn't save any data. If I comment that line out, it works a charm. But I need to have the UIDatePicker on today when the app loads.
I use this when the application starts:
NSDate *now = [[NSDate alloc] init];
[datePicker setDate:now];
This to fetch the note:
NSFetchRequest *fetch = [[NSFetchRequest alloc] init];
NSEntityDescription *testEntity = [NSEntityDescription entityForName:#"DatedText" inManagedObjectContext:self.managedObjectContext];
[fetch setEntity:testEntity];
NSPredicate *pred = [NSPredicate predicateWithFormat:#"dateSaved == %#", datePicker.date];
[fetch setPredicate:pred];
NSError *fetchError = nil;
NSArray *fetchedObjs = [self.managedObjectContext executeFetchRequest:fetch error:&fetchError];
if (fetchError != nil) {
NSLog(#"fetchError = %#, details = %#",fetchError,fetchError.userInfo);
}
noteTextView.text = [[fetchedObjs objectAtIndex:0] valueForKey:#"savedText"];
And this to save the note:
NSManagedObject *newDatedText;
newDatedText = [NSEntityDescription insertNewObjectForEntityForName:#"DatedText" inManagedObjectContext:self.managedObjectContext];
[newDatedText setValue:noteTextView.text forKey:#"savedText"];
[newDatedText setValue:datePicker.date forKey:#"dateSaved"];
NSError *saveError = nil;
[self.managedObjectContext save:&saveError];
if (saveError != nil) {
NSLog(#"[%# saveContext] Error saving context: Error = %#, details = %#",[self class], saveError,saveError.userInfo);
}
Remember NSDate saves not only DD/MM/YYYY but also HH:MM:SS.
At a guess I think when you pick a DD/MM/YYYY from the picker, it saves with a default time of 0:00:00 but in the case above when you set the picker date to now you are actually manipulating the HH:MM:SS to something else (even though you don't see it manually).
To illustrate what I'm trying to say, when you fetch is with a predicate of (dateSaved == picker.date) it is looking for a date in the format DD/MM/YYYY 00:00:00 and for arguments sake you may have saved it on DD/MM/YYYY 09:00:01.
You will need to do some formatting of your NSDate attribute if you want this to work.
Datepicker is by default set to todays date only. You don't need to do it manually.
