以下是代码

#import <EventKit/EventKit.h>

//事件市场
        EKEventStore *eventStore = [[EKEventStore alloc] init];
    
        //6.0及以上通过下面方式写入事件
        [eventStore requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {
            dispatch_async(dispatch_get_main_queue(), ^{
                if (error){
                    //错误
                }else if (!granted){
                    //被用户拒绝，不允许访问日历
                }else{
                    //创建事件
                    EKEvent *event  = [EKEvent eventWithEventStore:eventStore];
                    event.title     = @"我创建的日历事件";//标题
                    event.location = @"大山里";//位置
                    event.notes = @"难道我是文本";//文本
    
                    NSDateFormatter *tempFormatter = [[NSDateFormatter alloc]init];
                    [tempFormatter setDateFormat:@"dd.MM.yyyy HH:mm"];
                    
                    event.startDate = [NSDate dateWithTimeIntervalSinceNow:30.0f];
                    event.endDate   = [NSDate dateWithTimeIntervalSinceNow:300.0f];
                    event.allDay = NO;//是否全天，选择NO会在日历事件中显示出开始结束时间
                    
                    //添加提醒
                    [event addAlarm:[EKAlarm alarmWithRelativeOffset:-10.0f]];
                    [event addAlarm:[EKAlarm alarmWithRelativeOffset:-20.0f]];
                    
                    [event setCalendar:[eventStore defaultCalendarForNewEvents]];
                    NSError *err;
                    [eventStore saveEvent:event span:EKSpanThisEvent error:&err];
                    
                    UIAlertView *alert = [[UIAlertView alloc]
                                          initWithTitle:@"创建事件成功"
                                          message:@""
                                          delegate:nil
                                          cancelButtonTitle:@"Ok"
                                          otherButtonTitles:nil];
                    [alert show];
                    
                    NSLog(@"保存成功 event.timeZone:%@",event.timeZone);
                    
                }
            });
        }];
