Convert NSDictionary to NSMutableArray

Question

I have this code:

NSDictionary *jsonGuardado = [self dictionaryFromJson:JSON];
NSLog(@"HOLA %@",jsonGuardado);
NSMutableArray *arrayCodigos = [jsonGuardado objectForKey:@"code"];
codigos = arrayCodigos;

(Codigos is an NSMutableArray)

The NSLOG return this:

HOLA (
        {
        code = 22051310;
    },
        {
        code = 22051311;
    },
        {
        code = 22051312;
    },
        {
        code = 22051313;
    }
)

But right after this, a message error says:

-[JKArray objectForKey:]: unrecognized selector sent to instance

I search this error in Google and here and all the questions I found not help me.

I'm using the JSONKit for make the dictionaryFromJson method.

Answer 1

You try this,

NSArray *jsonGuardado = [self dictionaryFromJson:JSON];
NSLog(@"HOLA %@",jsonGuardado);
NSMutableArray *arrayCodigos = [NSMutableArray arrayWithArray:[jsonGuardado valueForKey:@"code"]];
NSLog(@"arrayCodigos %@", arrayCodigos);

It will print only values.

The parser returns an array and not a dictionary in your case.

[self dictionaryFromJson:JSON] returns a Json array but you are capturing it in NSDictionary
