Chipotle Gets an A An iPhone Development Experience RC Johnson Nick Niehoff Kim-Lan Tran Ryan Thomas

Initial Goal Write a burrito ordering app Wanted to release to App Store Chipotle had their own in development Decided not to pursue due to legal reasons

New idea Web service to check grade Use iPhone app to display grade Login with student idea and password Same structure if we were to make the burrito ordering app.

Structure MySQL database hosted on server Launch iPhone app that prompts user Input student id Input password Sends to server Server Accepts or declines Sends invalid login, or Grade information

iPhone app Objective-C UI built with Xcode No other way Sends request over HTTP Receives and parses XML to retrieve GPA Transcript

MySQL Stores grade information Student ID Password stored as SHA-1 GPA Grades More can be added

Server/PHP Accepts HTML request Apache server Parses username and password fields Formats response in XML Searches database for student ID and password Decline response sent if password or student ID not found Grade sent if found

iPhone Deployment Get developer account Create team Generate a certificate for the developer Register your device Create an App ID and link it to Xcode project Develop Provisioning profile and download to phone

Issues Building database Learning Objective-C None had experience Learning to use Xcode’s IDE Learning to use Interface Builder Learning Objective-C

Wrap Up Successfully implemented web service on iPhone Failed to due Chipotle app Possibly to lofty NDA Implemented app of similar structure

Future Chipotle If NDAs were provide structure could be used for Chipotle app Improve UI Grade Add more fields i.e. individual classes.
