Question

I would like to insert events in my app, so they can be viewed in iPhone Calendar.app. But since I don\'t want to mix the user events with those from my app, I wanted to cre

This is how you can check out whether a calendar already exists with specific title. If it does not exists then you can create it programatically.

Declare a Boolean Type Variable

BOOL doesExist=NO;
  EKEventStore *eventStore=[[EKEventStore alloc] init];

  NSArray *calanders=[eventStore   calendarsForEntityType:EKEntityTypeEvent];

  //Now Iterate through every calendar in the array and match its title  
  // with the title that you want to create



 for(EKCalendar calendar in calendars)
   {
         if([[calendar title] isEqualToString:@"youdesiredname"])
          {
                   doesExist=YES; 
          }

   }

// so now check if our bool variable contains value YES it means that a calendar with same name/title already exists.if no then you can create

 if(!doesExist)
    {
        NSString* calendarName = @"DesiredCalendarName";
        EKCalendar* calendar;


       EKSource* localSource;
       for (EKSource* source in eventStore.sources) {
       if (source.sourceType == EKSourceTypeLocal)
       {
        localSource = source;
        break;
       }




    if (!localSource)
        return;

       calendar = [EKCalendar calendarWithEventStore:eventStore];
       calendar.source = localSource;
       calendar.title = calendarName;


       EKEvent *event = [EKEvent eventWithEventStore:eventStore];
       calendar = [eventStore calendarWithIdentifier:self.calendarIdentifier];
       event.calendar = calendar;

      // Set the start date to the current date/time and the event duration to one hour
      NSDate *startDate = [NSDate date];
      event.startDate = startDate;
      event.endDate = [startDate dateByAddingTimeInterval:3600];

      //And to save the event to the event database:

       NSError *error = nil;
     BOOL result = [eventStore saveEvent:event span:EKSpanThisEvent commit:YES error:&error];
    if (result) 
    {
    NSLog(@"Saved event to event store.")
    } 
   else 
    {
     NSLog(@"Error saving event: %@.", saveError);
    }

      NSError* error;
      bool success= [eventStore saveCalendar:calendar commit:YES error:&error];
      if (error != nil)
      {
        NSLog(error.description);

      }

    }
