JSON parsing on iPhone SDK

Question

I have a certain json:

[
    {
        \"id\"        : 42422422,
        \"created\"   : 1329684013,
        \"name\"          : \"Test\"
    },
    {
               


        

Answer 1

With your non-error JSON payload you have a top level Array (noted by the beginning [ ), whilst with your error JSON payload you don't.

{
    "error" : {
        "code"      : "511",
        "message"   : "JSON error",
        "extra" : {
            "some"      : "text",
            "someextra" : "text"
        }
    }
}

The error code is a nested dictionary object, therefore you would use the following to parse it:

NSDictionary* json = [NSJSONSerialization
                              JSONObjectWithData:responseData
                              options:kNilOptions
                              error:&error];

NSString *errorCode = [NSString stringWithFormat:@"%@",[(NSDictionary*)[json objectForKey:@"error"]objectForKey:@"code"]];
