Example Login Method

authWithEmail.m

/*
This is an example of sending a POST request to a server that returns a JSON object containing a user ID, API key, etc. isSnagazineReachable is a method for checking if the server is available first. The main work is done by creating an NSDictionary with the data you want to post, passing that to the CCWebUtils class method postToUrl:params: which returns an NSString of the server response.
