Question

I have an NSMutableDictionary with three key/value pairs.

key1 - person object1 
key2 - person object2 
key3 - person object3

By comparing a string with the key in the dictionary, I need to retrieve the contents of the person object. How can I do this? Please help me. My code is:

NSArray *keys = [persondict allKeys];
    id key;
    for(int i= 0; i<[keys count]; ++i)
    {   key = [keys objectAtIndex:i];
    }
    for(id key in persondict){
        if ([key isEqual:agentrefattr]){
            //how to get the person object here?
            [aperson setPhoneNumber:aperson.PhoneNumber];
            [aperson setEmailAddress:aperson.EmailAddress];
            [aPersonName setGivenName:aPersonName.GivenName];
            [aPersonName setSurname:aPersonName.Surname];
            [aperson setPersonName:aperson.PersonName];

            [self.agentarray insertObject:aperson atIndex:index];
            [self.agentnamearray insertObject:aPersonName atIndex:index];
            aperson = [agentarray objectAtIndex:index];
            aPersonName = [agentnamearray objectAtIndex:index];

            NSLog(@"att:%@",agentrefattr);
            NSLog(@"Email :%@",aperson.EmailAddress);
            NSLog(@"Phone :%@",aperson.PhoneNumber);
            NSLog(@"Given Name :%@",aperson.PersonName.GivenName);
            NSLog(@"SurName :%@",aperson.PersonName.Surname);

Please help me with some hints. I want to access the properties, GivenName, Surname, etc., in the person object.

The keys in a dictionary are unique. So if agentrefattr is a string representing a key, yuu will only ever have one object in the dictionary with that key, so there is no need for a loop at all. Just do this:

aPerson = [personDict objectForKey: agentrefattr];
