Top level JSON object attributes Objective-c - objective-c

Question

How can I access high level JSON object in Objective-c? Here's the JSON
{
user: "user",
id: 39,
image: "img.png",
caption: "",
lat: "37",
lng: "-122",
created_at: 1356910240
}
... and I need to do something like this [JSON valueFor???:????]
I can add object "identifier" and access it like [JSON valueForKeyPath:#"identifier"] but wondering if there is another way?
identifier: {
user: "user",
id: 39,
image: "img.png",
caption: "",
lat: "37",
lng: "-122",
created_at: 1356910240
}
Thanks!

Typically, a JSON parser will return a dictionary/hash/associative array, whatever the language being used uses for key/value pairs.
In ObjectiveC, that would be NSDictionary. So your parser should be doing this:
NSDictionary *data = [SomeJSONParser decodeJson:jsonString];
Now to get "user" from that we would do:
[data objectForKey:#"user"];
But you want the root node? Well you already have it. The root node is the dictionary your parser spits out. There is no magic method to call, the root node is simply the result of the parser.
If your "custom parser" works differently, I would suggest you change it. Making this do what you want is entirely dependent on the API of your parser and what types of objects it returns, both things you left incredibly vague in your question.
