I am the auther of the blog.. I hope to get an example of that today. I believe it was you who commented on it wanting to see it.. but the idea is pretty simple.
If you read my blog there is an example to create a custom table cell so follow that.
I am assuming you have a unique ID for each set of data you want to grab.. to make it easy lets call it rowID. So pretty much you create a function in the custom cell called like
-(void)setID

int)id;
or such
then when you create the cell you do like
[cell setID:[jsonData objectForKey:@"id"]];
something like that.. then when you click the cell you can do another function to get the ID and then call the other json endpoint and pull in the data to the new view
