    <p>I have a simple <code>NSDictionary</code> that I am trying to populate with data from an external site via JSON that is returned. The JSON that is returned is fine but I am haveing trouble getting actual data for a specific key.</p> <p>Here is the JSON data printed to the console.</p> <p>This is my JSON data:</p> <pre><code>( { CategoryID = 12345; CategoryName = "Baked Goods"; }, { CategoryID = 12346; CategoryName = Beverages; }, { CategoryID = 12347; CategoryName = "Dried Goods"; }, { CategoryID = 12348; CategoryName = "Frozen Fruit &amp; Vegetables"; }, { CategoryID = 12349; CategoryName = Fruit; }, { CategoryID = 12340; CategoryName = "Purees &amp; Soups"; }, { CategoryID = 12341; CategoryName = Salad; }, { CategoryID = 12342; CategoryName = "Snack Items"; }, { CategoryID = 12343; CategoryName = Vegetables; } ) </code></pre> <p>The error I am getting is: </p> <blockquote> <p>Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFArray enumerateKeysAndObjectsUsingBlock:]: unrecognized selector sent to instance 0x6884000'</p> </blockquote> <pre><code>- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { NSError *error = nil; // Get the JSON data from the website NSDictionary *categories = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&amp;error]; if (categories.count &gt; 0){ NSLog(@"This is my JSON data %@", categories); [categories enumerateKeysAndObjectsUsingBlock: ^(__strong id key, __strong id obj, BOOL *stop) { NSLog(@"Key = %@, Object For Key = %@", key, obj); }]; } </code></pre> <p>I'm not sure why this is happening but I'm sure it's something simple like I am using the incorrect object or something.</p> <p>Help is appreciated.</p>

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
