JSON parsing odd node - ios

Question

I am parsing something like this from this website: http://www.prindlepost.org/?json=1
posts: [
{
....
categories: [],
tags: [],
....
One of the tags within 'post' is this:
author: {
id: 43,
slug: "connergordon_2016",
name: "Conner Gordon",
first_name: "Conner",
last_name: "Gordon",
nickname: "connergordon_2016",
url: "",
description: "Conner is a web and social media intern at the Prindle Institute. A Political Science major from Indiana, Conner's ethical interests lie in memory studies, conflict analysis and the ethics of representation. He also has interests in literature, art and photography."
},
This is how I am parsing the rest successfully:
// convert to JSON
NSError *myError = nil;
NSDictionary *res = [NSJSONSerialization JSONObjectWithData:self.responseData options:NSJSONReadingMutableLeaves error:&myError];
// extract specific value...
NSArray *results = [res objectForKey:#"posts"];
for (NSDictionary *result in results)
{
....
// loop through the array of categories
NSArray *categories = [result objectForKey:#"categories"];
for (NSDictionary *category in categories)
{
// ID
NSString *tempIDCategoryString = [category objectForKey:#"id"];
NSInteger *UniqueCategoryID = [tempIDCategoryString intValue];
// slug
NSString *Categoryslug = [category objectForKey:#"slug"];
// title
NSString *Categorytitle = [category objectForKey:#"title"];
// description
NSString *Categorydescription = [category objectForKey:#"description"];
// parent
NSString *Categoryparent = [category objectForKey:#"parent"];
// post_count
NSString *Categorypost_count = [category objectForKey:#"post_count"];
}
// </categories>
}
I have no idea how to parse this author node out of the array of objects within 'post'. Its not an array and it doesn't look like a JSON object to me. I might be wrong though. Help?

Answer 1

Author is a dictionary node.You can try this.
for (NSDictionary *result in results)
{
....
//get the author dictionary
NSDictionary *postDict = [result objectForKey:#"author"];
// loop through the array of categories
NSArray *categories = [result objectForKey:#"categories"];
...
}

Answer 2

Its very much simple...just access it with valueForKey
NSArray *results = [res objectForKey:#"posts"];
[results[#"author"] valueForKey:#"id"];
And you are done
