Protocol is HTTP requests made simple. One method to call to send off a GET, POST, PUT, or DELETE. Pass in a block to that method to handle its response there you have it.
- Setting of base URL for all requests
- Enabline of activity indicator in status bar
- Send GET, POST, PUT, and DELETE requests
- Pass in block to get raw NSData or serialized NSArray or NSDicitionary from a JSON response
- Map JSON responses to models
- Add headers to be set on each request (great for sessions)
- Easy, easy file upload
- Manual caching of route responses (great for images)
- Enabling of mock responses (great for when an API isn't ready yet)
