iOS:打开带有填充日期的日历应用新事件屏幕 [英] iOS: Open a Calendar app New Event screen with populated date

问题描述

是否可以使用填充的开始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 日历和提醒简介，但这似乎是一种矫枉过正.我也尝试过 calshow://，但似乎也没有用，或者我找不到正确的方案.

Is it possible to redirect a user to Calendar app New Event screen programmatically with populated start and end dates? I am aware of Introduction to Calendars and Reminders, but that seems to be an overkill. I have also tried calshow://, but didn't seem to work either or I am couldn't find a correct scheme.

推荐答案

@import EventKit;
@import EventKitUI;

然后使用这个来展示 eventkit:

then present eventkit using this:

- (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.

Meanwhile there are some delegates for giving detail of end dates start date of calendar.

#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

This createEvent will create new calendar
