Parsing Json Output correctly - ios

Question

I am trying to correctly target the elements within the Json Output and I am getting closer but I presume there is a easy and obvious way I am missing.
My Json looks like this with a upper level event.
JSON SNIPPET UPDATED
chat = (
(
{
Key = senderId;
Value = {
Type = 0;
Value = "eu-west-1:91afbc3f-890a-4160-8903-688bf0e9efe8";
};
},
{
Key = chatId;
Value = {
Type = 0;
Value = "eu-west-1:be6457ce-bac1-412d-9307-e375e52e22ff";
};
},
{
Key = timestamp;
Value = {
Type = 1;
Value = 1430431197;
};
},
//Continued
I am targeting this level using
NSArray *chat = array[#"chat"];
for ( NSDictionary *theCourse in chat )
{
NSLog(#"---- %#", theCourse);
// I tried the following to target the values
//NSLog(#"chatId: %#", [theCourse valueForKey:#"Key"]);
//NSLog(#"timestamp: %#", theCourse[#"senderId"] );
}
}
I need to parse the value data for each key which if I was using an array would do like [theCourse valueForKey:#"Key"] but I think I may not be going deep enough?
As you would expect, [theCourse valueForKey:#"Key"] gives me the Key values but I need the associate values of those keys.

You can create an easier dictionary:
NSArray *chat = array[#"chat"][0];
NSMutableDictionary* newDict = [NSMutableDictionary dictionary];
for (NSDictionary* d in chat)
[newDict setValue:d[#"Value"][#"Value"] forKey:d[#"Key"]];
Now you can use the newDict.
NSLog(#"chatId: %#", [newDict valueForKey:#"chatId"]);
