How to output data using NSJSONSerialization?

Question

I'm trying to output some data using NSJSONSerializationusing the code below.

This log statement works NSLog(@"publicData: %@", publicData); but then it crashes when I try to get the "description" of the dictionary NSLog(@"data: %@", [dict objectForKey:@"description"]);

my error message: unrecognized selector sent to instance. Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFDictionary objectAtIndex:]: unrecognized selector sent to instance...'

I've included the NSLog output.

NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL
                                                          URLWithString:@"http://******.com/api/feed"]];

NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];

NSError *jsonParsingError = nil;
NSArray *publicData = [NSJSONSerialization JSONObjectWithData:response options:0 error:&jsonParsingError];

NSLog(@"data from publicData: %@", publicData);
NSDictionary *dict;

for(int i=0; i<[publicData count];i++)
{
    dict= [publicData objectAtIndex:i];
    NSLog(@"data: %@", [dict objectForKey:@"description"]);

}


publicData: {
data =     (
            {
        address =             {
     address = "street address";
            city = cityname;
            lat = "42.000237034667";
            lng = "12.492805660226";
            province = provincename;
        };
        "category_id" = 20;
        description = "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

        id = 1;
        slug = "title-in-en";
        title = "title in En";
    },
            {
        address =             {
            address = "street address";
            city = cityname;
            lat = "42.000237034667";
            lng = "12.492805660226";
            province = provincename;
        };
        "category_id" = 20;
        description = "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

        id = 5;
        slug = "title-in-en";
        title = "title in En";
    },

thanks for any help

I optimized a little the code provided by codeplasma and it's looking like this:

 NSDictionary *publicData =  [NSJSONSerialization JSONObjectWithData:response
                                                                options:0              
                                                                  error:&jsonParsingError];
    NSArray *objects = [publicData objectForKey:@"data"];
    for(NSDictionary *element in objects) {
       NSLog(@"the description is %@",[element objectForKey:@"description"]);
    } 

Your publicData is NSDictionary not NSArray.
