标题: ios - 为什么通知适用于 NSHourCalendarUnit 但不适用于 NSWeekCalendarUnit？

我不明白为什么 LocalNotification 可以完美地与 NSHourCalendarUnit 一起工作，但永远不会与 NSWeekCalendarUnit 和 NSDayCalendarUnit 一起工作，尽管它显示了正确的时间日志!!当设置 weekday 我需要它来触发时，一定有什么我错过了。它会是什么？

请查看我的代码日志出来，以便您可以指导我正在做的错误:

-(void) Monday {   // 9th Notification Every 1:35

NSCalendar *calendar = [NSCalendar currentCalendar];
calendar.timeZone = [NSTimeZone timeZoneWithName"GMT"];

NSDateComponents *components = [calendar components: NSDayCalendarUnit | NSYearCalendarUnit | NSWeekCalendarUnit fromDate:[NSDate date]];

components.weekday = 2;
components.hour   = 10;
components.minute = 56;
components.second = 35;

NSDate *fire = [calendar dateFromComponents:components];
NSLog(@"The Fire Day is:: %@", fire);


UILocalNotification *notif = [[UILocalNotification alloc]  init] ;
if (notif == nil)
    return;

notif.fireDate = fire;
notif.repeatInterval= NSWeekCalendarUnit ;
notif.soundName = @"ring.wav";
notif.alertBody = [NSString stringWithFormat: @"THANKS for Your HELP "] ;
[[UIApplication sharedApplication] scheduleLocalNotification:notif] ;

NSLog(@"*****NEW LOG Notification Details*****%@", notif);
}

这是日志:

2014-01-20 10:09:12.935 daily notification test[17591:c07] The Fire Day is:: 2014-01-20 10:10:35 +0000

*日志更新:*

2014-01-20 10:56:21.694 daily notification test[17823:c07] The Fire Day is:: 2014-01-20 10:56:35 +0000

.

Best Answer-推荐答案

只需替换

notif.repeatInterval= NSHourCalendarUnit ;

与

notif.repeatInterval= NSWeekCalendarUnit;

编辑

现在试试这个，它可能会有所帮助

NSCalendar *gregorian1 = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
        [gregorian1 setLocale:[NSLocale currentLocale]];

        NSDateComponents *nowComponents = [gregorian1 components:NSYearCalendarUnit | NSWeekCalendarUnit | NSHourCalendarUnit | NSMinuteCalendarUnit | NSSecondCalendarUnit fromDate:[NSDate new]];

        [nowComponents setWeekday:2]; //Monday
       [nowComponents setWeek: [nowComponents week] + 1]; //Next week
        [nowComponents setHour:8]; //8a.m.
       [nowComponents setMinute:0];
        [nowComponents setSecond:0];

        NSDate *beginningOfWeek = [gregorian1 dateFromComponents:nowComponents];
