重复HMTimerTrigger多天（例如：每周一，周三......就像iOS 10家庭应用程序一样）

Question

我查看了iOS 10家庭应用。屏幕截图仅从Home应用程序中捕获。

自从过去两天以来，我一直在努力实现HMTimerTrigger重复功能。我的要求是我必须在每个星期一，星期二和星期五重复触发。我找到的是我只能添加一天（周一或周二......但不是周一和周二），如下所示。

  unsigned flags = NSCalendarUnitYear | NSCalendarUnitMonth | NSCalendarUnitWeekOfYear | NSCalendarUnitDay | NSCalendarUnitHour | NSCalendarUnitMinute;
  NSDate *fireDate = [NSDate date];
  NSDateComponents *recurrenceComponents = [[NSDateComponents alloc] init];
  recurrenceComponents.weekday = 2; // For monday

  NSDateComponents *dateComponents = [[NSCalendar currentCalendar] components:flags fromDate:fireDate];
  fireDate = [[NSCalendar currentCalendar] dateFromComponents:dateComponents];

  HMTimerTrigger *trigger = [[HMTimerTrigger alloc] initWithName:triggerName.text
                                                          fireDate:fireDate
                                                          timeZone:nil
                                                        recurrence:recurrenceComponents
                                                recurrenceCalendar:[NSCalendar currentCalendar]];

感谢您阅读我的帖子。任何想法/建议都会非常有帮助。

Answer 1

即使Apple在其HomeKit应用程序中使用此功能，公众也无法使用此功能。您可以做的最好的事情是每天创建多个触发器，但用户会感到困惑。

请在其上打开雷达错误here

Answer 2

几年前我使用通知做同样的事情。您无法使用一个实例创建多个触发器。所以你必须为每一天创建它。我希望这个例子可以给你一些想法。

NSCalendar *calendar = [NSCalendar autoupdatingCurrentCalendar] ;
NSDateComponents *componentsForReferenceDate = [calendar components:(NSYearCalendarUnit | NSWeekCalendarUnit |  NSHourCalendarUnit | NSMinuteCalendarUnit| NSSecondCalendarUnit | NSWeekdayCalendarUnit) fromDate:[NSDate date]];
NSDate *referenceDate = [calendar dateFromComponents:componentsForReferenceDate] ;
NSDateComponents *componentsForFireDate = [calendar components:(NSYearCalendarUnit | NSWeekCalendarUnit |  NSHourCalendarUnit | NSMinuteCalendarUnit| NSSecondCalendarUnit | NSWeekdayCalendarUnit) fromDate: referenceDate];

NSArray *arrayDays = [NSArray arrayWithObjects:@"1",@"3",@"5", nil];
for (int i=0; i<[arrayDays count]; i++)
{
    // set components for time 2:00 p.m.
    [componentsForFireDate setWeekday:[[arrayDays objectAtIndex:i] intValue]];
    [componentsForFireDate setHour: 14];
    [componentsForFireDate setMinute:0];
    [componentsForFireDate setSecond:0];
    NSDate *firstDateOfNotification = [calendar dateFromComponents: componentsForFireDate];

    UILocalNotification *notification1 = [[UILocalNotification alloc]  init] ;
    notification1.fireDate = firstDateOfNotification;
    notification1.timeZone = [NSTimeZone localTimeZone] ;
    notification1.alertBody = [NSString stringWithFormat: @"Complete your daily survey"] ;
    notification1.alertAction = @"go back";
    notification1.repeatInterval= NSWeekCalendarUnit;
    notification1.soundName = UILocalNotificationDefaultSoundName;
    [[UIApplication sharedApplication] scheduleLocalNotification:notification1] ;
}
