Select in NSArray from generated from JSON - objective-c

Question

I have an NSArray created from a JSON file.
If I just Print the Array to the console I get the following output:
Click me.
First part of file:

My Question is: How do I get the name of an item at an index ?
I tried
[[[[news objectAtIndex:0]objectForKey:#"items"]objectAtIndex:2] objectForKey:#"name"];
News is the array that contains the Data !
Hope you can help

Answer 1

You seem to have a dictionary consisting of several arrays of dictionaries. I think you want something like this... (edit: like mentioned in the comments, it depends which array of dictionaries you need to get the name from, as there seem to be several to chose from in the results).
NSArray *array = [resultDictionary objectForKey:#"attribute_controlled_attached_particles"];
for (NSDictionary *aDictionary in array){
NSString *name = [aDictionary objectForKey:#"name"];
// do what you want with the string...
// could be useful if you for instance need to make an array of all the names
}
Or of course:
NSString *someString = [[array objectAtIndex:3] objectForKey:#"name"];

Answer 2

You have got a dictionary containing another dictionary (not a smart idea), so you should get the dictionary inside it using the objectForKey: selector. Now if you are able to get the key-value of a dictionary, you wouldn't have problems doing it N times.
The [] operator allows you to access the values of an array/dictionary and it works like objectAtIndex:/valueForKey: . Here is how to do it:
NSDictionary* result= json[#"result"];
NSArray* acabArray= result[#"attribute_controlled_attached_particles"];
for(NSDictionary* acabDict in acabArray)
{
NSNumber* num= acabDict[#"attach_to_rootbone"];
NSString* name= acabDict[#"name"];
// Obtain also the other key-values in a similar way
// Do what you want with these values, I suggest to build a custom
// object to hold all these values, and put every object in a mutable array.
}

Answer 3

You have an NSDictionary containing a NSDictionary (keyed by "result") containing an NSArray (keyed by "attribute_controlled_attached_particles"). To get this containg array, you need to do:
NSArray *resultArray = [[jsonDictionary objectForKey:#"result"] objectForKey:#"attribute_controlled_attached_particles"];
Inside the resultArray, you have an ordered list of dictionaries representing news items. So, to get the "name" string for the first index, do
NSDictionary *itemDictionary = [resultArray objectAtIndex:0];
NSString *name = [itemDictionary objectForKey:#"name"];
To enumerate all items, you need to iterate through the resultArray.
