通过本地通知重复间隔

Question

我想使用自定义fireDate设置本地通知。它应该在每个星期天和星期一晚上7点发送。我住在欧罗巴。因为周历，我是否必须注意某些事情？

我的代码看着那样的时刻：

[[UIApplication sharedApplication] cancelAllLocalNotifications];

NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSCalendarIdentifierGregorian];

NSDate *now = [NSDate date];

NSDateComponents *componentsForFireDate = [calendar components:(NSCalendarUnitYear |   NSCalendarUnitHour | NSCalendarUnitMinute| NSCalendarUnitSecond | NSCalendarUnitWeekday) fromDate: now];

[componentsForFireDate setWeekday: 1] ;
[componentsForFireDate setHour: 19] ;
[componentsForFireDate setMinute:22] ;
[componentsForFireDate setSecond:0] ;

NSDate *fireDateOfNotification = [calendar dateFromComponents: componentsForFireDate];

// Create the notification
UILocalNotification *notification = [[UILocalNotification alloc]  init] ;

notification.fireDate = fireDateOfNotification ;
notification.timeZone = [NSTimeZone localTimeZone] ;
notification.alertBody = [NSString stringWithFormat: @"Wake up"] ;

notification.soundName=UILocalNotificationDefaultSoundName;

修改

我记录了fireDate（2015-01-01 18:22:00 +0000）。首先它是一个小时到早，第二个是错误的日期）
