I am using the following code to create an event within the iPhone's calendar;
EKEvent *event = [EKEvent eventWithEventStore:eventStore];
event.title = #"DHSB Assignment: %#", Assignment1.text;
event.startDate = [[NSDate alloc] init];
event.endDate = [[NSDate alloc] initWithTimeInterval:600 sinceDate:event.startDate];
[event setCalendar:[eventStore defaultCalendarForNewEvents]];
NSError *err;
[eventStore saveEvent:event span:EKSpanThisEvent error:&err];
[EKEventStore release];
NSLog(#"Successfully added '%#' to the calendar", Assignment1.text);
Why is this saving an event with the name "DHSB Assignment: %#" rather than "DHSB Assignment: Example Text"?
Thank you.
event.title = [NSString stringWithFormat:#"DHSB Assignment: %#", Assignment1.text];
Your current code is equivalent to
[event setTitle:#"DHSB Assignment: %#"];
[Assignment1 text];
…which is valid, so it compiles and runs fine even though it isn’t doing what you want.

I'm developing an app in which when user add any event as his favorite, I'm adding that event to iCal but how do i remove that event from iCal if user removes that particular event from his favorite.?
Here is my code:
NSDate *date = [NSDate dateWithTimeIntervalSince1970:[[self.parentDetailArray valueForKey:#"start_time_num"] intValue]];
NSDateFormatter *dateformatter=[[NSDateFormatter alloc]init];
[dateformatter setLocale:[NSLocale currentLocale]];
[dateformatter setDateFormat:#"dd-MM-yyyy"];
NSString *dateString=[dateformatter stringFromDate:date];
EKEventStore *eventStore = [[EKEventStore alloc] init];
if([eventStore respondsToSelector:#selector(requestAccessToEntityType:completion:)])
{
[eventStore requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {
if (granted){
//---- codes here when user allow your app to access theirs' calendar.
EKEvent *event = [EKEvent eventWithEventStore:eventStore];
event.title = title;
event.startDate = date;
event.endDate = [[NSDate alloc] initWithTimeInterval:1000 sinceDate:event.startDate];
[event setCalendar:[eventStore defaultCalendarForNewEvents]];
NSError *err;
[eventStore saveEvent:event span:EKSpanThisEvent error:&err];
// Here I'm trying to get the identifier of that event but m getting only (null)
self.str = [[NSString alloc] initWithFormat:#"%#", event.eventIdentifier];
[self.arrayofEventId addObject:self.str];
//[self performCalendarActivity:eventStore];
}else
{
//----- codes here when user NOT allow your app to access the calendar.
}
}];
}
else {
//---- codes here for IOS < 6.0.
EKEvent *event = [EKEvent eventWithEventStore:eventStore];
event.title = #"Testing for calendar";
event.startDate = [[NSDate alloc] init];
NSLog(#"%#",event.startDate);
[event setCalendar:[eventStore defaultCalendarForNewEvents]];
NSError *err;
[eventStore saveEvent:event span:EKSpanThisEvent error:&err];
//[self performCalendarActivity:eventStore];
}
How do i get the event identifier n remove that particular event from iCal. any help would be appreciated.
You could write all app generated event ID's to file and then load them back up next time the app loads. This way you can keep track of which events your app created. Then you may want to try this method:
- (BOOL)removeEvent:(EKEvent *)event span:(EKSpan)span commit:(BOOL)commit error:(NSError **)error
Save with this:
NSString *id = [[NSString alloc] initWithFormat:#"%#", event.eventIdentifier];
Remove with this:
EKEvent *event = [eventStore eventWithIdentifier:id];
NSError *error = nil;
[eventStore removeEvent:event span:EKSpanThisEvent error:&error];
Apple has documentation on the EKEventStore here.
Can anybody tell me how to make a repeating (weekly,daily,monthly) event for iOS Calendar events. My current implementation is something like this:
EKEvent *event = [EKEvent eventWithEventStore:eventStore];
event.title = [cellValue objectForKey:#"ZEVENTNAME"];
event.notes = [cellValue objectForKey:#"ZEVENTDESCRIPTION"];
event.location = [cellValue objectForKey:#"ZLOCAITONname"];
NSString * dateStart =[cellValue objectForKey:#"ZEVENTSTARTDATE"];
NSString * dateEnd =[cellValue objectForKey:#"ZEVENTENDDATE"];
NSDateFormatter *_formatter=[[NSDateFormatter alloc]init];
[_formatter setDateFormat:#"yyyyMMdd"];
NSDate *sDate = [_formatter dateFromString:dateStart];
NSDate *eDate = [_formatter dateFromString:dateEnd];
[_formatter setDateFormat:#"MM/dd/yyyy"];
event.startDate = sDate;
event.endDate = eDate;
event.calendar = [eventStore defaultCalendarForNewEvents];
NSError *error;
[eventStore saveEvent:event span:EKSpanThisEvent error:&error];
I have gone through developer help from apple but couldn't get the way how to implement.
Thanks
I wrote this code but it doesn't work, can you help me please? I'm stuck on it for last 2 hours.
- (IBAction)addBirthday:(id)sender {
NSString *name = self.textField.text;
NSDate *date = [self.datePicker date];
EKEventStore *eventStore = [[EKEventStore alloc] init];
[eventStore calendarsForEntityType:EKEntityTypeEvent];
EKEvent *event = [EKEvent eventWithEventStore:eventStore];
event.title = [NSString stringWithFormat:#"%#’s Birthday", name];
event.startDate = date;
event.endDate = date;
NSArray *calendars = [eventStore
calendarsForEntityType:EKEntityTypeEvent];
NSLog(#"ARRAY: %#", [calendars objectAtIndex:0]);
[event setCalendar: [calendars objectAtIndex:0]];
NSError *err;
[eventStore saveEvent:event span:EKSpanThisEvent error:&err];
}
The birthdays calendar is likely read only
I have tried putting this:
EKEventStore *eventStore = [[EKEventStore alloc] init];
EKEvent *event = [EKEvent eventWithEventStore:eventStore];
event.title = [NSString stringWithFormat:#"DHSB Assignment: %#", Assignment1.text];
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:#"M/d"];
event.startDate = [formatter dateFromString:dateField.text];
NSDateFormatter *formatter2 = [[NSDateFormatter alloc] init];
[formatter2 setDateFormat:#"M/d"];
event.endDate = [formatter2 dateFromString:dateField.text];
[event setCalendar:[eventStore defaultCalendarForNewEvents]];
[eventStore saveEvent:event span:EKSpanThisEvent error:&err];
[EKEventStore release];
NSLog(#"Successfully added '%#' to the calendar", Assignment1.text);
...but the event isn't added to the calendar if I enter a date in the format of "DD/MM/YYYY".
Why is this?
Thanks!
I think the correct format should be:
[formatter setDateFormat:#"dd/MM/yyyy"];
Try putting a NSLog on the dateFromString method to be sure you're getting the right result
EDIT: you may also need to set the correct locale for the date according to your needs.
I think your format string is wrong:
#"dd/MM/yyyy";
Might give better results.
By the way - what is the point of passing in an NSError* pointer to a function and not checking the return value or the error. Try replacing this line:
[eventStore saveEvent:event span:EKSpanThisEvent error:&err];
With something like this:
BOOL success = [eventStore saveEvent:event span:EKSpanThisEvent error:&err];
if (!success) {
NSLog(#"Cannot save event. %#", [err localizedDescription];
}
Not perfect error checking but it will give you some idea of what is happening while you are developing.
I'm trying to remove events that i have created from the iPhone calendar.
I tried this, but it always returns NO:
[eventStore removeEvent:event span:EKSpanThisEvent error:&err];
I created the event as follows and it works:
eventStore = [[EKEventStore alloc] init];
event = [EKEvent eventWithEventStore:eventStore];
event.title = #"EVENT TITLE";
NSDateFormatter * dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyy-MM-dd:HH:mm"];
NSDate * date = [[NSDate alloc] init];
date = [dateFormatter dateFromString:#"2010-8-15:12:30"];
[date retain];
event.startDate = date;
event.endDate = [[NSDate alloc] initWithTimeInterval:600 sinceDate:event.startDate];
[event setCalendar:[eventStore defaultCalendarForNewEvents]];
NSError *err;
[eventStore saveEvent:event span:EKSpanThisEvent error:&err];
Is there a way to remove this event? Or it would be be better that if I try to write this event again it only modifies it instead of creating a new one.
Thanks,
After creating the event I save the eventIdentifier in an array:
[eventStore saveEvent:event span:EKSpanThisEvent error:&err];
NSString* str = [[NSString alloc] initWithFormat:#"%#", event.eventIdentifier];
[arrayofCalIDs addObject:str];
To delete the events:
EKEventStore* store = [[[EKEventStore alloc] init] autorelease];
EKEvent* event2 = [store eventWithIdentifier:[arrayofCalIDs objectAtIndex:i]];
if (event2 != nil) {
NSError* error = nil;
[store removeEvent:event2 span:EKSpanThisEvent error:&error];
}
[myPath release];
Just an FYI for the answer above. It is found on the web on with this link:
http://tech.vniup.com/index.php/iphone/objective-c/how-to-delete-event-from-iphone-calendar-programmatically.html
My only suggestion is that if you are building an array of objects each object ideally would be the event. Then do a reverse array operation because the latest event will always be at the bottom.
NSMutableArray *reverseArray = [NSMutableArray arrayWithCapacity:[eventsList count]];
for (id element in [eventsList reverseObjectEnumerator]) {
[reverseArray addObject:element];
}
eventsList = reverseArray;
And also in the display of the events be nice to your users and display the start date of the event.
Anyway, after you have an array objects that are EKEvents you can do this which is MUCH easier.
EKEvent *eventToRemove = [myEventStore eventWithIdentifier:thisEvent.eventIdentifier ];
if ([eventToRemove.eventIdentifier length] > 0) {
NSError* error = nil;
[myEventStore removeEvent:eventToRemove span:EKSpanThisEvent error:&error];
}
Then you can remove that same event from you array of events for the table display....easy!
