Ios UILocalNotification可在特定日期重复触发

我正在开发闹钟应用程序，我想做重复的闹钟功能，就像在iOS闹钟应用程序一样，我们可以选择重复选项，如每周一，每周二，。。。同样地

示例：如果仅选择“每周一”、“每周三”和“每周一” 接下来的星期一、星期三和星期五 应发出相应的警报通知

我试过：

  NSCalendar *calendar = [NSCalendar currentCalendar];
  NSDateComponents *componentsForFireDate = [calendar components:(NSCalendarUnitYear | NSCalendarUnitWeekOfYear |  NSCalendarUnitHour | NSCalendarUnitMinute| NSCalendarUnitSecond | NSCalendarUnitWeekday) fromDate: [dictionaryForAlarm objectForKey:kAlarmSnoozeDate]];

 NSArray *arrayForRepeatDays = @[@"2",@"4",@"6"];

 for (NSString *dayOfWeek in arrayForRepeatDays) {

     [componentsForFireDate setDay:[dayOfWeek integerValue]];
     localNotification.repeatInterval =  NSCalendarUnitWeekOfMonth;;

     [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
}

但这两天都没有着火，请纠正我

非常感谢你

我认为您需要这样编写代码：

NSCalendar *calendar = [NSCalendar currentCalendar];
  NSDateComponents *componentsForFireDate = [calendar components:(NSCalendarUnitYear | NSCalendarUnitWeekOfYear |  NSCalendarUnitHour | NSCalendarUnitMinute| NSCalendarUnitSecond | NSCalendarUnitWeekday) fromDate: [dictionaryForAlarm objectForKey:kAlarmSnoozeDate]];

 NSArray *arrayForRepeatDays = @[@"2",@"4",@"6"];

 for (NSString *dayOfWeek in arrayForRepeatDays) {

     [componentsForFireDate setWeekday: [dayOfWeek integerValue]] 
     [componentsForFireDate setHour: 10] ; // here you can set hr as per you need
     localNotification.repeatInterval =  NSWeekCalendarUnit;
     localNotification.fireDate=[calendar dateFromComponents:componentsForFireDate];
     [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
}

我想这两个是让这一切顺利的原因：

[componentsForFireDate setWeekday: [dayOfWeek integerValue]] 
localNotification.repeatInterval =  NSWeekCalendarUnit;

NSCalendarUnitWeekOfMonth自NSWeekCalendarUnit仍未发出通知以来已使用NSCalendarUnitWeekOfMonth，而且在我保存它时，立即触发3个通知（因为今天保留为星期五、星期一和星期三已过）如何处理这个问题？检查我更新的答案我想你忘记设置FireDate了setHour的确切含义是什么？它指的是那天的时间，例如你设置的星期一，但在星期一哪个时间？？？那场火灾？？所以，对于设置一天的时间，我们使用hr，min，secsure，我会试试这个
