iOS：打开带有填充日期的日历应用新事件屏幕

Question

是否可以使用填充的开始日期和结束日期以编程方式将用户重定向到日历应用“新事件”屏幕？我知道Introduction to Calendars and Reminders，但这似乎有点矫枉过正。我也试过calshow://，但似乎也没有用，或者我找不到正确的方案。

Answer 1

@import EventKit;
@import EventKitUI;

然后使用这个来展示 eventkit：

- (IBAction)ScheduleClicked:(id)sender {

EKEventStore *eventStore = [[EKEventStore alloc]init];
if([eventStore respondsToSelector:@selector(requestAccessToEntityType:completion:)]) {
    [eventStore requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted,NSError* error){
        if(!granted){
        NSString *message = @"Hey! This Project Can't access your Calendar... check your privacy settings to let it in!";
        dispatch_async(dispatch_get_main_queue(), ^{

  // Present alert for warning.
            });
        }else{

            EKEventEditViewController *addController = [[EKEventEditViewController alloc] initWithNibName:nil bundle:nil];
            addController.event = [self createEvent:eventStore];
            addController.eventStore = eventStore;

            [self presentViewController:addController animated:YES completion:nil];
            addController.editViewDelegate = self;
            }
    }];
  }
}

同时有一些代表提供日历的结束日期开始日期的详细信息。

#pragma mark - eventEditDelegates -
- (void)eventEditViewController:(EKEventEditViewController *)controller didCompleteWithAction:(EKEventEditViewAction)action{
    if (action ==EKEventEditViewActionCanceled) {
        [self dismissViewControllerAnimated:YES completion:nil];
    }
    if (action==EKEventEditViewActionSaved) {
        [self dismissViewControllerAnimated:YES completion:nil];
    }
}


#pragma mark - createEvent -
-(EKEvent*)createEvent:(EKEventStore*)eventStore{
    EKEvent *event = [EKEvent eventWithEventStore:eventStore];
    event.title = @"New Event";

    event.startDate = @"Your start date";
    event.endDate = @"Your end date";

    event.location=@"Location";
    event.allDay = YES;
    event.notes =@"Event description";

    NSString* calendarName = @"Calendar";
    EKCalendar* calendar;
    EKSource* localSource;
    for (EKSource *source in eventStore.sources){
        if (source.sourceType == EKSourceTypeCalDAV &&
            [source.title isEqualToString:@"iCloud"]){
            localSource = source;
            break;
        }
    }
    if (localSource == nil){
        for (EKSource *source in eventStore.sources){
            if (source.sourceType == EKSourceTypeLocal){
                localSource = source;
                break;
            }
        }
    }
    calendar = [EKCalendar calendarForEntityType:EKEntityTypeEvent eventStore:eventStore];
    calendar.source = localSource;
    calendar.title = calendarName;
    NSError* error;
   [eventStore saveCalendar:calendar commit:YES error:&error];
    return event;
}

此 createEvent 将创建新日历
