Ekevents gets adding multiple times in calendar? - ios

Question

In my application i am adding an event to devices calendar.I am doing like this
if ([db.saveCalenderSettings isEqualToNumber:[NSNumber numberWithBool:YES]]){
NSPredicate *predicateForEventOnDate = [store predicateForEventsWithStartDate:strtdate endDate:[strtdate dateByAddingTimeInterval:60*60] calendars:nil];
NSArray *eventsOnDate = [store eventsMatchingPredicate:predicateForEventOnDate];
__block BOOL eventExists = NO;
[eventsOnDate enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
EKEvent *eventToCheck = (EKEvent*)obj;
if([note isEqualToString:eventToCheck.notes]) {
eventExists = YES;
*stop = YES;
}
}];
NSLog(#"%#",eventsOnDate);
if(! eventExists) {
NSLog(#"Event not exists so adding");
EKEvent *event = [EKEvent eventWithEventStore:store];
event.title = subject; //give event title you want
event.notes = note ;
event.startDate = strtdate;
event.endDate = [event.startDate dateByAddingTimeInterval:60*60];
event.calendar = [store defaultCalendarForNewEvents];
// EKAlarm *alarm = [EKAlarm alarmWithRelativeOffset:60*15*-1];
// event.alarms = [NSArray arrayWithObject:alarm];
NSError *err = nil;
[store saveEvent:event span:EKSpanThisEvent commit:YES error:&err];
if (!err) {
[db setSavedtocalender:#"yes"];
}
else {
// NSLog(#" Event not created");
[db setSavedtocalender:#"no"];
}
}
else {
NSLog(#"Event exists");
[db setSavedtocalender:#"yes"];
}
}
But the problem is the same event gets added multiple times in the default calendar .Can anybody tells me where i am going wrong?

Hi For each and every event one id is alloted.
Please Check is the event is added or not.If event added then store event id and check agin before saving event again.
For getting Event Id :
//save the event id if you want to access this later
NSString *eventId=event.eventIdentifier;
For Future Refernce :
// To add event in Calender App
EKEventStore *store = [EKEventStore new];
[store requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {
if (!granted) { return; }
EKEvent *event = [EKEvent eventWithEventStore:store];
event.title = #"To meet Chandu.";
event.startDate = [NSDate date]; //today
event.endDate = [event.startDate dateByAddingTimeInterval:60*60]; //set 1 hour meeting
event.calendar = [store defaultCalendarForNewEvents];
event.location=#"Sandriver Technologies";
NSError *err = nil;
[store saveEvent:event span:EKSpanThisEvent commit:YES error:&err];
NSLog(#"%#",event.eventIdentifier); //save the event id if you want to access this later
eventId=event.eventIdentifier;
}];
//to remove event from app
[store requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {
if (!granted) { return; }
EKEvent* eventToRemove = [store eventWithIdentifier:eventId];
if (eventToRemove) {
NSError* error = nil;
[store removeEvent:eventToRemove span:EKSpanThisEvent commit:YES error:&error];
}
}];
// Note: Get all event list
//To get Appropriate calender
NSCalendar *calendar = [NSCalendar currentCalendar];
if ([store respondsToSelector:#selector(requestAccessToEntityType:completion:)])
{
/* iOS Settings > Privacy > Calendars > MY APP > ENABLE | DISABLE */
[store requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error)
{
if ( granted )
{
NSLog(#"User has granted permission!");
// Create the start date components
NSDateComponents *oneDayAgoComponents = [[NSDateComponents alloc] init];
oneDayAgoComponents.day = -1;
NSDate *oneDayAgo = [calendar dateByAddingComponents:oneDayAgoComponents
toDate:[NSDate date]
options:0];
// Create the end date components
NSDateComponents *oneYearFromNowComponents = [[NSDateComponents alloc] init];
oneYearFromNowComponents.year = 1;
NSDate *oneYearFromNow = [calendar dateByAddingComponents:oneYearFromNowComponents
toDate:[NSDate date]
options:0];
// Create the predicate from the event store's instance method
NSPredicate *predicate = [store predicateForEventsWithStartDate:oneDayAgo
endDate:oneYearFromNow
calendars:nil];
// Fetch all events that match the predicate
NSArray *events = [store eventsMatchingPredicate:predicate];
NSLog(#"The content of array is%#",events);
}
else
{
NSLog(#"User has not granted permission!");
}
}];
}
