general introduction
General Introduction
  • Business overview
    • We produce a variety of iPhone applications
    • Content generally comes from third parties
  • iPhone development overview
    • We write iPhone exclusively in Objective-C
    • Supporting technologies include RoR, PHP and DHTML
    • Apple’s DRM complicates distribution
hungry guide project introduction
Hungry Guide Project Introduction
  • Each book follows a predefined structure
  • Contains venues for a specific location in a city
  • LA client provides content
  • COS location houses codebase and application development
  • Client wants to produce over 300 guides
previous application workflow
Previous Application Workflow
  • Assets and content come from LA
  • Codebase, development tool chain and DRM in COS
  • Current template is poorly designed
  • Embedding content is tedious and error-prone
design goals for new workflow
Design Goals for new Workflow
  • Enforce better defined workflow
  • Allow for multiple projects to be created at once
  • Remove tedious, error prone process of inserting assets into a template
  • Streamline template-to-application process
design overview
Design Overview
  • Use a common backend
  • Write a custom CMS for client input
    • Allow client to input all assets and content
    • Allow client to create associations between data models
  • Create a process for generating a preview for client signoff
  • Create a process for compiling iPhone applications after client signoff
  • Create a generic reader application and bundle assets to package for it
implementation
Implementation
  • MySQL chosen for backend
  • CMS was written using RoR
    • Workflow for uploading content and creating venues
    • Workflow for creating books from a list of venues
    • Acts as Attachment for Asset management
  • CMS made heavy use of AJAX and REST
implementation ii
Implementation II
  • PHP process provided preview and signoff
  • Ruby process compiled HTML pages and bundled assets for phone
  • Obj-C generic reader to parse HTML structure
outcomes
Outcomes
  • Production was finished
  • Final product buggy on iPhone
    • UIWebview issues
    • Static HTML structure insufficient for dynamic app
  • Overall process shows promise
  • Process possible to refine to meet new demands
  • Lessons learned
    • Manage scope creep
    • Look into a premade CMS solution
    • Favor a native solution
    • Keep the technology stack small
future iterations
Future Iterations
  • Adding to book creation workflow in CMS
  • Implementing client preview in RoR instead of PHP
  • Creating and bundling Obj-C source instead of DHTML
  • Creating secure download server for Obj-C source
sources
Sources
  • Apache usage documentation
  • Apple development documentation
  • Thomas Fielding’s Doctoral Dissertation [related chapters]
