UILocalNotification 在特定日期重复触发

Question

我正在开发闹钟应用程序，我想做与 iOS 闹钟应用程序中相同的重复闹钟功能，我们可以在其中选择重复选项，如每周一、每周二等。

示例：如果我只选择每周一、每周三和每周 星期五然后对于所有即将到来的星期一、星期三和星期五 应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着火，请纠正我

提前感谢您！

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];
}

我猜这两个会让这个工作：

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