Decode Feedly JSON data - json

Question

I currently have the code below to decode some received JSON data. However, since Feedly doesn't give any indexes back I don't know how to properly decode the JSON data. This is an example of JSON I receive back:
[
{
"id": "user/c805fcbf-3acf-4302-a97e-d82f9d7c897f/category/tech",
"label": "tech"
},
{
"id": "user/c805fcbf-3acf-4302-a97e-d82f9d7c897f/category/design",
"label": "design"
}
]
And if I let the code below run, the NSLog outputs it perfectly. But how do I fetch the label variables from res?
- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
NSLog(#"connectionDidFinishLoading");
NSLog(#"Succeeded! Received %d bytes of notifications",[self.responseData length]);
// convert to JSON
NSError *myError = nil;
NSDictionary *res = [NSJSONSerialization JSONObjectWithData:self.responseData options:NSJSONReadingMutableLeaves error:&myError];
NSLog(#"res value contains: %#", res);
}

Answer 1

If short to get label values use [res valueForKeyPath:#"label"];
But to make it work in right way you need to change type of res to NSArray because provided JSON contains array of dictionary.
Then you can traverse through with for-in.
NSError *myError = nil;
NSArray *res = [NSJSONSerialization JSONObjectWithData:self.responseData options:NSJSONReadingMutableLeaves error:&myError];
for (NSDictionary *d in res) {
NSLog(#"label %#",[d objectForKey:#"label"]);
}
NSLog(#"res value contains: %#", res);
