ios - 我被困在 iphone 应用程序中选择天数的闹钟？

Question

我想要一个用于报警的小型 iOS 应用程序。一旦我选择了特定的日期和时间，就应该发出通知。

如果我选择所有天，每天都应该发出警报。如果您已经有代码，请您帮我处理这个应用程序并发送给我。

先感谢您。

试试下面的代码：

UILocalNotification *localNotif = [[UILocalNotification alloc]init];

NSCalendar *calendar = [NSCalendar currentCalendar];
NSDate *datePickerDate = [NSDate date];
NSDateComponents *dateComponents = [calendar components:(NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit) fromDate:datePickerDate];
NSDateComponents *timeComponents = [calendar components:(NSHourCalendarUnit | NSMinuteCalendarUnit | NSSecondCalendarUnit) fromDate:datePickerDate];

NSDateComponents *dateComps = [[NSDateComponents alloc]init];
[dateComps setYear:[dateComponents year]];
[dateComps setMonth:[dateComponents month]];

[dateComps setHour:[timeComponents hour] ];
[dateComps setMinute:[timeComponents minute]];
[dateComps setSecond:00];

NSDate *fireDate = [calendar dateFromComponents:dateComps];
//NSLog(@"%@",fireDate);
localNotif.fireDate = fireDate;
localNotif.soundName = UILocalNotificationDefaultSoundName;
//localNotif.repeatInterval = 1.0;
localNotif.alertAction = @"Alarm";
//NSLog(@"%@",alarmId);

//for alarm once
if ([alarm.repeat_mode_id intValue] == 0) {


} else if([alarm.repeat_mode_id intValue] == 1) { //for alarm every day
    localNotif.repeatInterval = NSDayCalendarUnit;
}
localNotif.alertBody = alarm.alarm_label;
[[UIApplication sharedApplication]scheduleLocalNotification:localNotif];

请使用以下步骤每天创建警报。

1. 您创建警报并将此警报存储在 NSUSerDefaults 或数据库中。例如：开火日期：12-11-2013 10.30AM

2. 一旦警报完成。即收到警报，在已存储的日期值中更新一天。

   - (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification NS_AVAILABLE_IOS(4_0)
   {
        UIApplicationState state = [[UIApplication sharedApplication] applicationState];
         if (state == UIApplicationStateActive)
       {
            // The Alarm Received The Pointer come to This.
       }
   else
   {
        // You click notification. the pointer come in else condition
    NSDate *alerm_time_str=[alarmData valueForKey:@"FireDate"];
   
   
    NSDate *fire_date;
   
           if ([alerm_time_str timeIntervalSinceNow] < 0.0) {
   
               NSLog(@"Date is Passed");
   
               int daysToAdd = 1;
               NSDate *newDate1 = [alerm_time_str dateByAddingTimeInterval:60*60*24*daysToAdd];
               fire_date=newDate1;
   
           }
           else
           {
               fire_date=alerm_time_str;
           }
   

   }

如果有任何澄清让我。
