UILocalNotification觸發日期為每天的固定時間

Question

我想將firedate的UILocalNotification設置為UILocalNotification 11:00 AM和11:00 PM（ UILocalNotification每12小時一次）。 我該如何實現？ 請提出建議。

創建兩個單獨的UILocalNotifications並指定重復間隔。

enum {
   NSEraCalendarUnit = kCFCalendarUnitEra,
   NSYearCalendarUnit = kCFCalendarUnitYear,
   NSMonthCalendarUnit = kCFCalendarUnitMonth,
   NSDayCalendarUnit = kCFCalendarUnitDay,
   NSHourCalendarUnit = kCFCalendarUnitHour,
   NSMinuteCalendarUnit = kCFCalendarUnitMinute,
   NSSecondCalendarUnit = kCFCalendarUnitSecond,
   NSWeekCalendarUnit = kCFCalendarUnitWeek,
   NSWeekdayCalendarUnit = kCFCalendarUnitWeekday,
   NSWeekdayOrdinalCalendarUnit = kCFCalendarUnitWeekdayOrdinal,
   NSQuarterCalendarUnit = kCFCalendarUnitQuarter,
   NSCalendarCalendarUnit = (1 << 20),
   NSTimeZoneCalendarUnit = (1 << 21),
};
typedef NSUInteger NSCalendarUnit;
