Ios5 iOS中的本地通知问题

我正在为表中的某些行设置特定日期和时间的本地通知。所以考虑

案例1：当用户第一次设置本地通知时，他从日期选择器中选择日期，我将其传递给本地通知对象firedate。

NSArray *notificationarray = [[UIApplication sharedApplication]scheduledLocalNotifications];
        if([notificationarray count]== 0)
        {
            m_alarmLocalNotification = [[UILocalNotification alloc] init];
            m_alarmLocalNotification.fireDate = DateTime;
            m_alarmLocalNotification.timeZone = [NSTimeZone defaultTimeZone];

            NSDictionary *infoDict = [NSDictionary dictionaryWithObject:m_Name forKey:@"ID"];
            m_alarmLocalNotification.userInfo = infoDict;

            [[UIApplication sharedApplication] scheduleLocalNotification:m_alarmLocalNotification];         

NSArray *notificationarray =  [[UIApplication sharedApplication]scheduledLocalNotifications];
        NSLog(@"notification count:%d",[notificationarray count]);
        for (int i = 0;i < [notificationarray count];i++)
        {
            UILocalNotification *notificationObject=[notificationarray objectAtIndex:i];
            NSString *Name=[notificationObject.userInfo valueForKey:@"ID"];
            if([Name isEqualToString:m_Name])
            {
                [[UIApplication sharedApplication] cancelLocalNotification:notificationObject];
            }
        }

案例2：修改本地通知日期。

    NSArray *notificationarray  = [[UIApplication sharedApplication]scheduledLocalNotifications];
                for (int i = 0;i < [notificationarray count];i++)
                {
                    UILocalNotification *notificationObject=[notificationarray objectAtIndex:i];
                    NSString *Name=[notificationObject.userInfo valueForKey:@"ID"];

                    if(Name isEqualToString:m_Name])
                    {
                        [[UIApplication sharedApplication] cancelLocalNotification:notificationObject];
                    m_alarmLocalNotification = [[UILocalNotification alloc] init];
                    m_alarmLocalNotification.fireDate = DateTime;
                    m_alarmLocalNotification.timeZone = [NSTimeZone defaultTimeZone];      


                    NSDictionary *infoDict = [NSDictionary dictionaryWithObject:m_noteName forKey:@"ID"];
                    m_alarmLocalNotification.userInfo = infoDict;

                    [[UIApplication sharedApplication] scheduleLocalNotification:m_alarmLocalNotification];   
                    }
                   else
                   {

                    m_alarmLocalNotification = [[UILocalNotification alloc] init];
                    m_alarmLocalNotification.fireDate = DateTime;
                    m_alarmLocalNotification.timeZone = [NSTimeZone defaultTimeZone];      


                    NSDictionary *infoDict = [NSDictionary dictionaryWithObject:m_noteName forKey:@"ID"];
                    m_alarmLocalNotification.userInfo = infoDict;

                    [[UIApplication sharedApplication] scheduleLocalNotification:m_alarmLocalNotification]; 
                }         

        }           

NSArray*notificationarray=[[UIApplication sharedApplication]ScheduledLocalNotification]；
对于（int i=0；i<[notificationarray count]；i++）
{
UILocalNotification*notificationObject=[notificationarray objectAtIndex:i]；
NSString*Name=[notificationObject.userInfo valueForKey:@“ID”]；
if（名称isEqualToString:m_Name]）
{
[[UIApplication sharedApplication]取消通知：通知对象]；
m_alarmLocalNotification=[[UILocalNotification alloc]init]；
m_alarmLocalNotification.fireDate=日期时间；
m_alarmLocalNotification.timeZone=[NSTimeZone defaultTimeZone]；
NSDictionary*infoDict=[NSDictionary Dictionary WithObject:m_noteName forKey:@“ID”]；
m_alarmLocalNotification.userInfo=infoDict；
[[UIApplication sharedApplication]scheduleLocalNotification:m_alarmLocalNotification]；
}
其他的
{
m_alarmLocalNotification=[[UILocalNotification alloc]init]；
m_alarmLocalNotification.fireDate=日期时间；
m_alarmLocalNotification.timeZone=[NSTimeZone defaultTimeZone]；
NSDictionary*infoDict=[NSDictionary Dictionary WithObject:m_noteName forKey:@“ID”]；
m_alarmLocalNotification.userInfo=infoDict；
[[UIApplication sharedApplication]scheduleLocalNotification:m_alarmLocalNotification]；
}         
}           

案例3：删除本地通知。

NSArray *notificationarray = [[UIApplication sharedApplication]scheduledLocalNotifications];
        if([notificationarray count]== 0)
        {
            m_alarmLocalNotification = [[UILocalNotification alloc] init];
            m_alarmLocalNotification.fireDate = DateTime;
            m_alarmLocalNotification.timeZone = [NSTimeZone defaultTimeZone];

            NSDictionary *infoDict = [NSDictionary dictionaryWithObject:m_Name forKey:@"ID"];
            m_alarmLocalNotification.userInfo = infoDict;

            [[UIApplication sharedApplication] scheduleLocalNotification:m_alarmLocalNotification];         

NSArray *notificationarray =  [[UIApplication sharedApplication]scheduledLocalNotifications];
        NSLog(@"notification count:%d",[notificationarray count]);
        for (int i = 0;i < [notificationarray count];i++)
        {
            UILocalNotification *notificationObject=[notificationarray objectAtIndex:i];
            NSString *Name=[notificationObject.userInfo valueForKey:@"ID"];
            if([Name isEqualToString:m_Name])
            {
                [[UIApplication sharedApplication] cancelLocalNotification:notificationObject];
            }
        }

NSArray*notificationarray=[[UIApplication sharedApplication]ScheduledLocalNotification]；
NSLog（@“通知计数：%d”，[notificationarray计数]）；
对于（int i=0；i<[notificationarray count]；i++）
{
UILocalNotification*notificationObject=[notificationarray objectAtIndex:i]；
NSString*Name=[notificationObject.userInfo valueForKey:@“ID”]；
if（[Name IsequalString:m_Name]）
{
[[UIApplication sharedApplication]取消通知：通知对象]；
}
}

面临的问题。 我不确定我的做法是否正确。 1） 即使我删除我的应用并重新安装它，默认的schedulednotification数组也不会被释放。我的意思是它包含一些以前的通知。 2） 每当我删除我的单元格时，我希望本地通知应该被删除

问候

如果在修改通知时使用以下代码，情况会如何

NSArray *notificationarray  = [[UIApplication sharedApplication] scheduledLocalNotifications];
    [notificationarray enumerateObjectsUsingBlock:^(UILocalNotification *notification,NSUInteger idx, BOOL *stop) {
        if ([[notification.userInfo valueForKey:@"ID"] isEqual:@""]) {
            notification.fireDate = [NSDate date];
        }
    }];
