iPhone - How to import native calendar events to my iphone app? - iphone

I am doing one simple application using iPhone calendar, where I need to import the iPhone native calendar events into my iPhone app. How can I do this. I have a piece of code but it doesn't seems to be working. I have added some events into my iPhone native calendar. But when i retrieve it's not fetching anything. Here is the piece of code.
-(IBAction)importCalEvents:(id)sender
{
NSArray *caleandarsArray = [[NSArray alloc] init];
caleandarsArray = [[eventStore calendars] retain];
NSLog(#"Calendars from Array : %#", caleandarsArray);
for (EKCalendar *CalendarEK in caleandarsArray)
{
NSLog(#"Calendar Title : %#", CalendarEK.title);
}
}

you can fetch all the calendar events like this.
import these 2 framworks (add if not exists into your project).
1 EventKit/EventKit.h
2) EventKitUI/EventKitUI.h
call this function on button click
-(void)EventList{
EKEventStore *eventStore = [[EKEventStore alloc] init];
NSDate *startDate = [[NSDate alloc] init];
NSDate *endDate = [[NSDate alloc] initWithTimeInterval:3600 sinceDate:startDate];
NSArray *calendars = [eventStore calendars];
NSPredicate *predicate = [eventStore predicateForEventsWithStartDate:startDate
endDate:endDate calendars:calendars];
NSArray *matchingEvents = [eventStore eventsMatchingPredicate:predicate];
EKEvent *anEvent;
NSLog(#"Total Events >> %d",[matchingEvents count]);
for (int j=0; j < [ matchingEvents count]; j++) {
anEvent = [matchingEvents objectAtIndex:j];
NSLog(#"Title >>>%#",anEvent.title);
NSLog(#"start date is %# \n End Date is >>> %#",anEvent.startDate,anEvent.endDate);
}
}
And set the startDate and EndDate as per your Requirement.
so you can get all the detatils you want.
Best Luck..

Get events from all the EKCalendar

I want to get events from all the calendars (home,work,calendar and birthday). I am getting events from the defaultcalendar, but cannot fetch events from Birthday calendar. Any help will be great.
This answer might help you:
NSDate* endDate = [NSDate dateWithTimeIntervalSinceNow:[[NSDate distantFuture] timeIntervalSinceReferenceDate]];
NSArray *calendarArray = [NSArray arrayWithObject:cal];
NSPredicate *fetchCalendarEvents = [eventStore predicateForEventsWithStartDate:[NSDate date] endDate:endDate calendars:calendarArray];
NSArray *eventList = [eventStore eventsMatchingPredicate:fetchCalendarEvents];
for(int i=0; i < eventList.count; i++){
NSLog(#"Event Title:%#", [[eventList objectAtIndex:i] title]);
}

parsing calender events

In my application I am retrieving all calender events using eventkit framework. Now I have parse it in to json to upload it to server. what is the best way to do this, kindly give me an idea if there are any parser libraries or framework which can parse calendar events. Below is the code i used to retrieve events
- (NSMutableArray *)fetchallevents {
NSDate *start = [NSDate distantPast];
NSLog(#"start date is : %#",start);
NSDate *finish = [NSDate distantFuture];
NSLog(#"start date is : %#",finish);
// use Dictionary for remove duplicates produced by events covered more one year segment
NSMutableDictionary *eventsDict = [NSMutableDictionary dictionaryWithCapacity:1024];
NSDate* currentStart = [NSDate dateWithTimeInterval:0 sinceDate:start];
int seconds_in_year = 60*60*24*365;
// enumerate events by one year segment because iOS do not support predicate longer than 4 year !
while ([currentStart compare:finish] == NSOrderedAscending) {
NSDate* currentFinish = [NSDate dateWithTimeInterval:seconds_in_year sinceDate:currentStart];
if ([currentFinish compare:finish] == NSOrderedDescending) {
currentFinish = [NSDate dateWithTimeInterval:0 sinceDate:finish];
}
NSPredicate *predicate = [eventStore predicateForEventsWithStartDate:currentStart endDate:currentFinish calendars:nil];
[eventStore enumerateEventsMatchingPredicate:predicate
usingBlock:^(EKEvent *event, BOOL *stop) {
if (event) {
[eventsDict setObject:event forKey:event.eventIdentifier]; } }];
currentStart = [NSDate dateWithTimeInterval:(seconds_in_year + 1) sinceDate:currentStart];
}
NSMutableArray *events =[[eventsDict allValues]mutableCopy];
//NSLog(#"the evenets for the day is : %#", events);
return events;
}

how i use iPhone calendar add event?

any suggestion is appreciated
bellow is peace of code. date for alarm is using to match work hours (users don't like to wakeup to do job :)
eventStore = [[EKEventStore alloc] init];

}

}

How can I programmatically create an iCal event in the default calendar?

How can I use Objective-C to programmatically create an iCal event in the default calendar? I want to check whether the event already exists and set the button state accordingly.
An example of how to programmatically create an iCAL event in the default calendar, using Objective-C. The code checks if the event already exists, and sets the button state accordingly. Here is the code by #codeburger:
-(void)initCalendar {
// An array of 1 dictionary object, containing START and END values.
NSMutableArray* pvDict = [[NSMutableArray alloc] initWithContentsOfURL:[NSURL URLWithString:PV_URL ]];
// Check if the private view event already exists in the default calendar.
// Then set the calendar button state.
// Get a entry point to the Calendar database.
self.store = [[EKEventStore alloc ] init ];
// Get an array of all the calendars.
NSArray *calendars = store.calendars;
// Get the default calendar, set by the user in preferences.
EKCalendar *defaultCal = store.defaultCalendarForNewEvents;
// Find out if this calendar is modifiable.
BOOL isDefaultCalModifiable = defaultCal.allowsContentModifications ;
// Create an event in the default calendar.
self.event = [ EKEvent eventWithEventStore:store ];
self.event.title = CHELSEA_SPACE ;
self.event.location = CHELSEA_ADDRESS ;
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];

NSString *endString = [[ pvDict objectAtIndex:0] objectForKey:#"ends" ];
NSDate *dateEnd = [dateFormatter dateFromString:endString];
self.event.startDate = dateStart;
self.event.endDate = dateEnd;
self.event.calendar = defaultCal ;
// Alternative code to add 2.5 hours to start time.
// [[NSDate alloc] initWithTimeInterval:9000 sinceDate:event.startDate];
// Search for events which match this date/time start and end.
// Compare the matched events by event TITLE.
NSPredicate *predicate = [store predicateForEventsWithStartDate:event.startDate
endDate:event.endDate calendars:calendars];
NSArray *matchingEvents = [store eventsMatchingPredicate:predicate];
self.calendarButton.enabled = NO;
if( ! isDefaultCalModifiable ) {
// The default calendar is not modifiable
return ;
}
if ( [ matchingEvents count ] > 0 ) {
// There are already event(s) which match this date/time start and end.
// Check if this event is the PV
EKEvent *anEvent;
int j;
for ( j=0; j < [ matchingEvents count]; j++) {
anEvent = [ matchingEvents objectAtIndex:j ] ;
if([ CHELSEA_SPACE isEqualToString: anEvent.title ]) {
// PV event already exists in calendar.
return;
}
}
[ anEvent release ];
}
self.calendarButton.enabled = YES;
[ pvDict release ];
}
-(void)addEventToCalendar:(id)sender {
NSError *error;
BOOL saved = [self.store saveEvent:self.event span:EKSpanThisEvent error:&error];
NSLog(#"Saved calendar event = %#\n", (saved ? #"YES" : #"NO"));
self.calendarButton.enabled = NO;
}
I've seen this question with no answer and felt like it should be edited giving full credit to #codeburger.
EKEventStore *eventStore = [[EKEventStore alloc] init];
EKEvent *event = [EKEvent eventWithEventStore:eventStore];
NSDate *date = [[NSDate alloc ]init];//today,s date
event.title = #"remainder";//title for your remainder
event.startDate=date;//start time of your remainder
event.endDate = [[NSDate alloc] initWithTimeInterval:1800 sinceDate:event.startDate];//end time of your remainder
NSTimeInterval interval = (60 *60)* -3 ;
EKAlarm *alarm = [EKAlarm alarmWithRelativeOffset:interval]; //Create object of alarm
[event addAlarm:alarm]; //Add alarm to your event
[event setCalendar:[eventStore defaultCalendarForNewEvents]];
NSError *err;
NSString *ical_event_id;
//save your event
if([eventStore saveEvent:event span:EKSpanThisEvent error:&err]){
ical_event_id = event.eventIdentifier;

How to Programmatically Create new Calendars on iPhone that will sync to iCal

I'm looking for a way to create a new Calendar on the iphone device programatically. I have been looking at Event Kit and it clearly states how to create a new event in a calendar and there is also a convenient way of gathering all the calendars in code, What I can't find is how to create a new one that is saved to the device.
Any ideas'
