NSJSONSerialization data in a different format - ios

Question

I am using Parse.com as a backend of my application, where I am currently storing the data there.
The data is a list of video game consoles. I was able to make an output of it, but instead of JSON data, the output is a big NSMutableArray.
This is my viewDidLoad:
- (void)viewDidLoad
{
[super viewDidLoad];
NSURL *url = [NSURL URLWithString:#"https://api.parse.com/1/classes/Consoles"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setURL:url];
[request setHTTPMethod:#"GET"];
[request setValue:#"APPLICATION_ID" forHTTPHeaderField:#"X-Parse-Application-Id"];
[request setValue:#"REST_API_KEY" forHTTPHeaderField:#"X-Parse-REST-API-Key"];
NSError *error;
id listOfConsoles = [NSJSONSerialization JSONObjectWithData:[NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil] options:NSJSONReadingMutableContainers error:&error];
NSLog(#"The list: %#", listOfConsoles);
}
The output:
The list: {
results = (
{
createdAt = "2013-03-21T07:26:04.149Z";
name = PlayStation;
objectId = vloIK0MZIA;
updatedAt = "2013-03-21T07:26:04.149Z";
},
{
createdAt = "2013-03-21T07:26:34.209Z";
name = Wii;
objectId = RIRpgbznlq;
updatedAt = "2013-03-21T07:26:34.209Z";
},
{
createdAt = "2013-03-21T07:26:39.391Z";
name = Xbox;
objectId = xBNgHtJbrV;
updatedAt = "2013-03-21T07:26:39.391Z";
}
);
}
What I want the output to be:
{
"results" : [
{
"objectId" : "vloIK0MZIA",
"updatedAt" : "2013-03-21T07:26:04.149Z",
"createdAt" : "2013-03-21T07:26:04.149Z",
"name" : "PlayStation"
},
{
"objectId" : "RIRpgbznlq",
"updatedAt" : "2013-03-21T07:26:34.209Z",
"createdAt" : "2013-03-21T07:26:34.209Z",
"name" : "Wii"
},
{
"objectId" : "xBNgHtJbrV",
"updatedAt" : "2013-03-21T07:26:39.391Z",
"createdAt" : "2013-03-21T07:26:39.391Z",
"name" : "Xbox"
}
]
}
BY THE WAY
Why is it that when I have a separate NSData in the code:
NSData *JSONData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
And change my NSJSONSerialization to:
id listOfConsoles = [NSJSONSerialization JSONObjectWithData:JSONData options:NSJSONReadingMutableContainers error:&error];
The output will be:
The list: {
error = unauthorized;
}

Answer 1

The first list is a NSDictionary with a single key called "results" which has an NSArray of NSDictionaries.
The second list is the same thing..
Edit 1.0:
Just to clarify, the second output is JSON, ok? Simply as that, just check here and validate yourself. The first one is the outputted JSON that is inside an NSObject. Of course there will be slight differences...

Answer 2

Your Authentication not done successfully. Please check APPLICATION_ID and REST_API_KEY values.

Answer 3

I was an idiot. I never realized that I tried to convert the JSON to something else, when I wanted the JSON data.
