Store multiple users in local notification

I am creating a UILocalNotification and I need to set multiple userInfo for it, how can I do this?

    // Create a new notification

    UIApplication* app = [UIApplication sharedApplication];

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

    alarm.fireDate = date;        
    alarm.timeZone = [NSTimeZone localTimeZone];
    alarm.alertBody = msg;        
    alarm.alertAction = @"View";            
    alarm.repeatInterval = NSYearCalendarUnit;
    alarm.soundName=@"happyBirthday.wav";
    alarm.applicationIconBadgeNumber = 1;    

   NSDictionary *userDict = [NSDictionary dictionaryWithObject:detailperson forKey:@"msg"];
   NSDictionary *userDictName = [NSDictionary dictionaryWithObject:detailperson2 forKey:@"name"];

   alarm.userInfo = userDict;
   alarm.userInfo = userDictName;

There can be several objects in the dictionary if all the keys are different:

NSDictionary *userDict = [NSDictionary dictionaryWithObjectsAndKeys:detailperson, @"msg", detailperson2, @"name", nil];

alarm.userInfo = userDict;

you need to use a combination of two dictionaries in combination with one dictionary, and then install this dictionary into user information.

        NSDictionary *dic=[NSDictionary dictionaryWithObjectsAndKeys:dic1,@"first",dic2,@"second", nil];

       alarm.userInfo=dic
