The titles come up but there is no author coming up

Could you post the code you have written for setting the author to the subtitle of the cell?

NSURL *blogURL = [NSURL URLWithString:@"http://blog.teamtreehouse.com/api/get_recent_summary/"];

NSData *jsonData = [NSData dataWithContentsOfURL:blogURL];

NSError *error = nil;

NSDictionary *dataDictionary =[NSJSONSerialization JSONObjectWithData:jsonData options:0 error:&error];

NSLog(@"%@", dataDictionary);
self.blogPosts = [dataDictionary objectForKey:@"posts"];

Is this the entire block of code you're using to extract the data from that URL? I don't see a HTTP request anywhere in there. Do this to fetch data and extract the data you need from the response:

1. Set up whatever networking API you will use to communicate with the server. There are several good ones to use out there, but in this case, we'll use Apple's NSURLSession networking API
2. Set up the URL endpoint
3. Set up the HTTP request. In this case, you'll be using the "GET" method to fetch data from the server.
4. Perform your request using NSURLSession's "NSURLSessionDataTask"
5. Serialize the response data using NSJSONSerialization
6. Parse the json and smile

NSURLSession *session = [NSURLSession sharedSession];
NSURL *blogURL = [NSURL URLWithString:@"http://blog.teamtreehouse.com/api/get_recent_summary/"];
NSURLRequest *request = [NSURLRequest requestWithURL:blogURL]; //the "GET" method is default so you don't have to explicitly define a request method
NSURLSessionDataTask *task = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
        NSDictionary *json = [NSJSONSerialization JSONObjectWithData:data option:kNilOptions error:&error];
//do your beautiful parsing here
    }
[task resume]; //make the magic happen

It's ok there was another section of code that talked about what displayed in each section that I did not post. I realised this morning that in this section I had capitalised the word Author and it therefore didn't recognise the lower case version in the JSON file. Thanks for your help
