Question

我正在开发报警应用程序，我想做与iOS闹钟应用程序相同的重复报警功能，我们可以选择重复选项作为每周一，每周二，......同样。

示例：如果我只选择每周一，每周三和每个星期五然后是所有即将到来的周一，周三和周五应该触发相应的警报通知。

我试过了：

  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];
}

但它在相应的日子里没有起火，为此纠正我

谢谢你的推荐！

我认为你需要做这样的代码：

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];
}

我猜这两个就像让这个有效：

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

UILocalNotification在特定日期内重复发射
