iphone - 将事件添加到 iPhone 应用程序的 iCal 中

Question

我的申请中有一个要求，当我预约某一天的医生时，该天应该添加到 iCal 中。它应该在该特定日期生成警报 View 。

所以，我不知道如何在 iCal 中添加事件。请给我一些答案。

情况是，我确实有一个包含该特定约会的“日期”和“注释”的字符串(NSString)。那么，如何将所有这些信息插入到 iCal 中。

代码:

- (NSArray *)fetchEventsForToday {

    NSDate *startDate = [NSDate date];

    // endDate is 1 day = 60*60*24 seconds = 86400 seconds from startDate
    NSDate *endDate = [NSDate dateWithTimeIntervalSinceNow:86400];

    // Create the predicate. Pass it the default calendar.
    NSArray *calendarArray = [NSArray arrayWithObject:defaultCalendar];
    NSPredicate *predicate = [self.eventStore predicateForEventsWithStartDate:startDate endDate:endDate 
                                                                    calendars:calendarArray]; 

    // Fetch all events that match the predicate.
    NSArray *events = [self.eventStore eventsMatchingPredicate:predicate];

    return events;
}


// Overriding EKEventEditViewDelegate method to update event store according to user actions.
- (void)eventEditViewController:(EKEventEditViewController *)controller 
          didCompleteWithAction:(EKEventEditViewAction)action {

    NSError *error = nil;
    EKEvent *thisEvent = controller.event;

    switch (action) {
        case EKEventEditViewActionCanceled:
            // Edit action canceled, do nothing. 
            break;

        case EKEventEditViewActionSaved:
            // When user hit "Done" button, save the newly created event to the event store, 
            // and reload table view.
            // If the new event is being added to the default calendar, then update its 
            // eventsList.
            if (self.defaultCalendar ==  thisEvent.calendar) {
                [self.eventsList addObject:thisEvent];
            }
            [controller.eventStore saveEvent:controller.event span:EKSpanThisEvent error:&error];
            [self.tableView reloadData];
            break;

        case EKEventEditViewActionDeleted:
            // When deleting an event, remove the event from the event store, 
            // and reload table view.
            // If deleting an event from the currenly default calendar, then update its 
            // eventsList.
            if (self.defaultCalendar ==  thisEvent.calendar) {
                [self.eventsList removeObject:thisEvent];
            }
            [controller.eventStore removeEvent:thisEvent span:EKSpanThisEvent error:&error];
            [self.tableView reloadData];
            break;

        default:
            break;
    }
    // Dismiss the modal view controller
    [controller dismissModalViewControllerAnimated:YES];

}

// Set the calendar edited by EKEventEditViewController to our chosen calendar - the default calendar.
- (EKCalendar *)eventEditViewControllerDefaultCalendarForNewEvents:(EKEventEditViewController *)controller 
{
    EKCalendar *calendarForEdit = self.defaultCalendar;
    return calendarForEdit;
}

我已经使用了这些函数和委托(delegate)方法。请告诉我，当用户收到提醒时，如何打开有关该事件的信息？

您需要EventKit framework 。您可以询问EKEventStore为其日历，然后使用这些日历创建一个谓词，让您 find events that match the criteria you're looking for 。或者您可以创建一个新的 EKEvent对象和save it into the event store .
