UILocalNotification按固定時間每天燃燒

Question

我想設置firedateUILocalNotification到上午11:00和下午11:00每天（意味着每12小時）。我怎樣才能做到這一點？請建議。

Answer 1

創建兩個單獨的UILocalNotifications並指定重複間隔。

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;
