Question

I have created an NSDictionary from a JSON file, but when I try to do

NSString *key = [NSString stringWithFormat:@"%i",indexPath.row];
NSDictionary *currentObject = [JSONdata objectForKey:key];

I error receive and error of -[__NSCFArray objectForKey:]: unrecognized selector sent to instance

When I do an NSLog of JSONdata this is my output:

(
    {
        1 =         {
            description = "";
            facets =             (
                                {
                    name = Red;
                },
                                {
                    name = Blue;
                },
                                {
                    name = Skinny;
                },
                                {
                    name = Standard;
                },
                                {
                    name = "Navy Blue";
                }
            );
            id = 1073;
            owner = 1001;
            "post_date" = 1341980987;
            transaction = 24;
            username = TonyB;
        };
    },
    {
        2 =         {
            description = "";
            facets =             (
                                {
                    name = "Bow Tie";
                },
                                {
                    name = Blue;
                },
                                {
                    name = Orange;
                },
                                {
                    name = Yellow;
                }
            );
            id = 1001;
            owner = 1001;
            "post_date" = 1340640012;
            transaction = 6;
            username = TonyB;
        };
    }
)

Am I correcting in thinking that the first set of keys that I should be able to get should be 1 and 2 using [JSONdata objectForKey:@"0"] or [JSONdata objectForKey:@"1"]? Or am I missing something?

Answer 1

The structure of your JSON is as Follow

NSArray containing NSDictionary

So you need to do this : [[JSONdata objectAtIndex:0] objectForKey:@"1"]

---

Also when in doubt you can always do this :
NSLog(@"JSONdata class == %@", [JSONdata class]);

And when you hit a NSDictionary you always have this method : - (NSArray *)allKeys that will return you an array of all the key of that dictionary.
