iOS 設置每天下午4點推送本地通知

UILocalNotification *notification=[[UILocalNotification alloc] init];
    if (notification!=nil) {//判斷系統是否支持本地通知
        notification.fireDate = [NSDate dateWithTimeIntervalSince1970:16*60*60*24];//本次開啟立即執行的周期
        notification.repeatInterval=kCFCalendarUnitWeekday;//循環通知的周期
        notification.timeZone=[NSTimeZone defaultTimeZone];
        notification.alertBody=@"哇哇哇";//彈出的提示信息
        notification.applicationIconBadgeNumber=0; //應用程序的右上角小數字
        notification.soundName= UILocalNotificationDefaultSoundName;//本地化通知的聲音
//notification.alertAction = NSLocalizedString(@"美女呀", nil);  //彈出的提示框按鈕
        notification.hasAction = NO;
        [[UIApplication sharedApplication]   scheduleLocalNotification:notification];
    }
