iOS-添加日程写入日历-Calendar

话不多说直接来

一、权限的获取

Privacy - Calendars Usage Description 是否允许此App使用日历？
Privacy - Reminders Usage Description 是否允许此App访问提醒事项？

二、手动写入日历日程-代码部分

// 导入EventKit 库
#import 

// 先来一波权限判断
- (void)saveCalendar {
    EKEventStore *eventStore = [[EKEventStore alloc] init];
    __weak typeof(self) weakSelf = self;
    //06.07 使用 requestAccessToEntityType:completion: 方法请求使用用户的日历数据库
    if ([eventStore respondsToSelector:@selector(requestAccessToEntityType:completion:)]) {
        // 获取访问权限
        [eventStore requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {
            if (error)
            {
                //报错啦
            }
            else if (!granted)
            {
                // 被用户拒绝，不允许访问日历，滚去开启权限
            }
            else
            {
                dispatch_async(dispatch_get_main_queue(), ^{
                    // 用户既然允许事件保存到日历，那就去保存吧
                    [weakSelf saveDataCalendar:eventStore];
                });
            }
        }];
    }
}


// 写入日历
- (void)saveDataCalendar:(EKEventStore *)eventStore {
    // 创建事件
    EKEvent *event  = [EKEvent eventWithEventStore:eventStore];

    // 这里拿当前时间 （自己写的话格式最好用 yyyy/MM/dd hh:mmaaa）
    NSDate *date = [NSDate date];
    
    event.title  = @"事件标题标标标" ;              //  事件标题
    event.location = @"事件地点地地地地" ;          //  事件地点
    event.notes = @"事件备注备备备";               //  事件备注
    event.startDate = [date dateByAddingTimeInterval:60 * 2];   // 开始时间
    event.endDate   = [date dateByAddingTimeInterval:60 * 30];  // 结束时间
    
    //第一次提醒  (几分钟后)
    [event addAlarm:[EKAlarm alarmWithRelativeOffset:60.0f * -5.0f]];
    
    [event setCalendar:[eventStore defaultCalendarForNewEvents]];
    NSError *err;
    [eventStore saveEvent:event span:EKSpanThisEvent error:&err];
}

三、利用系统界面写入日历日程-代码部分

// 导入EventKit和EventKitUI 库
#import 
#import 

- (void) saveCalendar {
    EKEventStore *eventStore = [[EKEventStore alloc]init];
    if([eventStore respondsToSelector:@selector(requestAccessToEntityType:completion:)]) {
        [eventStore requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted,NSError* error){
            if(!granted){
                dispatch_async(dispatch_get_main_queue(), ^{
                    //TODO: 提示需要权限
                });
            }else{
                
                EKEvent *event = [EKEvent eventWithEventStore:eventStore];
                event.title = @"日历标题";
                
                EKCalendar* calendar;
                calendar = [EKCalendar calendarForEntityType:EKEntityTypeEvent eventStore:eventStore];
                NSError* error;
                [eventStore saveCalendar:calendar commit:YES error:&error];
                
                EKEventEditViewController *addController = [[EKEventEditViewController alloc] initWithNibName:nil bundle:nil];
                addController.event = event;
                addController.eventStore = eventStore;
                
                [self presentViewController:addController animated:YES completion:nil];
                addController.editViewDelegate = self;
            }
        }];
    }
}

#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];
    }
}
