Question

Just for example I have next NSDictionary

{      
        {
            "first_name" = Paul;
            "last_name" = Blabla;
            online = 0;

        },
        {
            "first_name" = Jess;
            "last_name" = BlaBlaBla;
            online = 0;

        },
}

when I use method [myDictionary objectForKey:@"first_name"] it always returning (null),
my guess is that this is happening because I have more than one parameters that returns.

What can I do to return all “first_name”?

What you’ve shown in your post is an array of dictionaries, not a dictionary (the outer punctuation should be parentheses not curly braces). So, since it’s an array, you have to get which object you’re referring to first with objectAtIndex:, for instance, and then use object:forKey: to get the particular value you want.
