My talk at MobileCamp Boston, Feb 19 2011. The deck covers materials for constructing a simple Twitter reader using Three20 and RESTKit frameworks.

1. iOS Frameworks Samuel Chow, MobyFab @Cybersam

2. End-to-End Platform More apps are connected to remote RESTful endpoints for richer content and user experience Better visuals + HTTP connection + JSON parser

3. iOS Frameworks REST ASIHTTPRequest – http://allseeing-i.com/ASIHTTPRequest/ JSON Framework (aka SBJSON) – http://stig.github.com/json-framework/ YAJL – http://github.com/gabriel/yajl-objc RESTKit – http://getsharekit.com/ ShareKit – http://getsharekit.com/ Visual Three20 – http://three20.info Core-Plot – http://code.google.com/p/core-plot/

4. Three20 Visual Out of the box, you get these for free Custom Views and Buttons Tab and Grid Table Items Labels Special View Controllers

5. Three20 Non-visual Utilities Network Caching Remote image retrieval Data persistence HTTP Request/Response JSON parsing (via JBSON or YAJL) View navigation CSS-like styling mode

6. Three20 Object Flow

8. Prepare to send request

9. Parse response

10. Visual configuration

11. Visual layout

12. Transform data objects to table items

14. Low-level vs High-level Three20 and common REST Frameworks Too much time spent on crafting request, parsing responses, and creating representation of remote data Enter RESTKit High-level abstraction of REST operations It enables you to focus on modeling RESTful objects to your in-memory object Conversely, if you want lower level, more complete HTTP swiss-army knife then consider ASIHTTPRequest

15. Three20 + RESTKit Integration RESTKit provides the RKRequestTTModel as a convenient class for integration with Three20 No need to supply the parsing logic in requestDidFinishLoad: Simply map the data object properties to the JSON elements Supply the URL (host and path) RESTKit will do the heavy lifting for you
