获取应用背景模式的本地通知

应用在背景模式下运行时如何获取本地通知？

谢谢

UILocalNotification *localNotif = [[UILocalNotification alloc] init];if (localNotif == nil)    return;localNotif.fireDate =[startDate addTimeInterval:60];NSLog(@""%@""localNotif.fireDate);localNotif.timeZone = [NSTimeZone defaultTimeZone];localNotif.alertAction = @""View"";localNotif.soundName = UILocalNotificationDefaultSoundName;NSString *notifStr=[NSString stringWithFormat:@""Hey looks like you're meeting up with %@ why don't you let your other friends know what fun they're missing out on? Share a photo :)""[itemDict objectForKey:@""fname""]];NSDictionary *infoDict = [NSDictionary dictionaryWithObjectsAndKeys:notifStr @""notifKey""nil];localNotif.userInfo = infoDict;// Schedule the notification[[UIApplication sharedApplication] scheduleLocalNotification:localNotif];[localNotif release];

解决方案

-(void)insert:(NSDate *)fire{    [[UIApplication sharedApplication]cancelAllLocalNotifications];    self.localNotification = [[UILocalNotification alloc] init];    if (self.localNotification == nil)    {        return;    }    else    {        self.localNotification.fireDate = [NSDate dateWithTimeIntervalSinceNow:60];        self.localNotification.alertAction = nil;        self.localNotification.soundName = UILocalNotificationDefaultSoundName;        self.localNotification.alertBody = @""Hey looks like you're meeting up with %@ why don't you let your other friends know what fun they're missing out on? Share a photo :)"";        self.localNotification.alertAction = NSLocalizedString(@""Read Msg"" nil);        self.localNotification.applicationIconBadgeNumber=1;        self.localNotification.repeatInterval=0;        [[UIApplication sharedApplication] scheduleLocalNotification:self.localNotification];    }}- (void)application:(UIApplication *)app didReceiveLocalNotification:(UILocalNotification *)notif{    [[UIApplication sharedApplication]cancelAllLocalNotifications];    app.applicationIconBadgeNumber = notif.applicationIconBadgeNumber -1;    notif.soundName = UILocalNotificationDefaultSoundName;    [self _showAlert:[NSString stringWithFormat:@""%@""Your msg withTitle:@""Title""];}- (void) _showAlert:(NSString*)pushmessage withTitle:(NSString*)title{    [self.alertView_local removeFromSuperview];    self.alertView_local = [[UIAlertView alloc] initWithTitle:title message:pushmessage delegate:self cancelButtonTitle:@""OK"" otherButtonTitles:nil];    [self.alertView_local show];    if (self.alertView_local)    {    }}

看看能不能实现
