Suggestion: Show Error in Alert View if Base URL is wrong

[jefflinwood]

If the user doesn't have the Drupal site running, or the network is down, or the URL is wrong, the app should pop up an AlertView saying that there was a failure to connect to the server

For this particular problem there are many possible cases some of them are covered by me and on some of them I am working. Like bas URL ( than httpStatusCode == 404 not found) that is handled and no connection to the server (than httpStatusCode == 0) that is also handled.

But what if connection requires proxy authentication or your service provider requires user to be authenticated ( for example my service provider displays login page and set "Connection" header value to "Close" until I provide valid username password combination ) or any other error which may have httpStatusCode 200 but we don't get JSON object -----> to handle this situation I have added one IF that check weather retrieved JSON object is nil or not other wise show UIAlertView

Ok, that's great!
