将JSON从数组解析为NSDictionary？ （ObjC）

Question

Looking at it for some time now and tried every possible way in my knowledge, but still without any success.

How can I parse the following JSON to get the first array into a dictionary? I am using the AFNetworking library and the responseObject returns the following:

(
y,
    (
    yeti,
    "yeti tumbler",
    "yoga pants",
    "yoga mat",
    "yeezy boost 350",
    "yeti cup",
    yoga,
    yeezy,
    "young living essential oils",
    yugioh
),
    (
            {
        nodes =             (
                            {
                alias = garden;
                name = "Home & Kitchen";
            },
                            {
                alias = "outdoor-recreation";
                name = "Outdoor Recreation";
            },
                            {
                alias = "fan-shop";
                name = "Sports Fan Shop";
            }
        );
    },
            {
    },
            {
    },
            {
    },
            {
    },
            {
    },
            {
    },
            {
    },
            {
    },
            {
    }
),
    (
)

)

Now, how can I get the first array into a NSDictionary?

(
    yeti,
    "yeti tumbler",
    "yoga pants",
    "yoga mat",
    "yeezy boost 350",
    "yeti cup",
    yoga,
    yeezy,
    "young living essential oils",
    yugioh
)

ObjC code:

    - (void)requestJSONWithQuery:(NSString *)query
{
    if (!_requestOperation.isCancelled) [_requestOperation cancel];
    query = [query stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
    NSString *string = [NSString stringWithFormat:_URLDictionaryForAPIs[@(_APIType)], query];
    NSURL *url = [NSURL URLWithString:string];
    NSURLRequest *request = [NSURLRequest requestWithURL:url];
    _requestOperation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
    _requestOperation.responseSerializer = [AFJSONResponseSerializer serializer];
    __block FFFGoogleSearchAutoCompleteController *selfInBlock = self;
    [_requestOperation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {


     //   NSLog(@"%@", responseObject);
        selfInBlock.suggestions = [(NSDictionary *)responseObject mutableArrayValueForKey:query];
        [selfInBlock refreshSuggestionTable];


    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {


    }];
    [_requestOperation start];
}

This will return the following error:

Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<NSTaggedPointerString 0xa0000000000006b1> valueForUndefinedKey:]: this class is not key value coding-compliant for the key K.'

Answer 1

["k",["kindle","kindle fire","kindle books","keurig","knife","kate spade","keyboard","kindle paperwhite","knife sharpener","kindle fire case"],[{"nodes":[{"name":"Kindle Store","alias":"digital-text"},{"name":"Electronics","alias":"electronics"},{"name":"Computers","alias":"computers"}]},{},{},{},{},{},{},{},{},{}],[]] is not a dictionary. Your response is an array. The first item is the query. The second seems to be the thing that you want. I would try to do this for a test:

selfInBlock.suggestions = [(NSArray *)responseObject objectAtIndex:1];
