Hi Hector I just checked out the link? If the data requires access then your app needs to make a call to the server to get permission. You need to be using NSURLAuthenticationChallenge it has methods associated with which will allow your app firstly to get access to the data before parsing it.

Once you have ti then your need to parse in the url with NSURL and use NSJSONSerialization to retrieve the data your interested in.

Without seeing your full code I can't give you to much advice hope this helps!!
