I write code. I ride my bike. I've got great friends. Life is good.

Walkin Technology

Theres a lot to Walkin. As a developer I think sharing the included Libraries of the Project is a great overview of the Technologies used, if you are not a developer feel free to skip ahead for a higher level explaination of what makes up Walkin.

  • UIKit and Foundation, standard iOS User Interfaces

  • CoreLocation for checkins to stores

  • CoreBluetooth for iBeacons which confirm checkins

  • AdSupport for the advertising identifier

  • libsqlite3 for analytics
  • libxml2.2 for analytics
  • SystemConfiguration for device infromation such as your phone's version
  • MobileCoreServices for device tracking, mostly to prevent cheating

  • MediaPlayer for our tutorial Movie

  • CoreMedia for Video Playback
  • CoreVideo from Video Playback

  • Social for sharing on Weibo

  • ImageIO for manipulating the image when posting to social sites
  • Addressbook and AddressbookUI for sending emails
  • CoreTelephony for calling customer support

  • QuartzCore for a lot of custom animations in the User Interface

  • CoreGraphics for animations as well
  • OpenGLES for particle emmiters and rendering our Augmented Reality scanner
  • GLKit for rendering the same things as above
  • CoreMotion for augmented reality games

  • CoreText for rendering HTML type text into the views of Walkin

  • AudioToolbox for playing our cool checkin sound

  • OpenAL for the same

  • Mapkit for finding nearby stores

  • XCTest for testing my code

I love cocoapods and open source code. It helped Walkin progress much faster as a one man project. Heres our podfile

platform :ios, "5.0"

xcodeproj 'Walkin.xcodeproj'

pod 'SSToolkit', '~> 1.0.4' ##For Collection Views
pod 'AFNetworking', '~> 1.3.1' ##For talking to our API over the network
pod 'SDWebImage', '<= data-preserve-html-node="true" 3.4' ## Great for persisting commonly viewed images

    pod 'GHUnit', '0.5.8'
end

Not everything we use is from cocoapods though, Heres the open source code used by Walkin

  • NSURLRequest+CURL
  • KIImagePager
  • RIAlertViewBlocks
  • CocoaTouchBarcodes
  • Cocoa With Love's PageTableView Subclasses
  • WeChat SDK
  • Weibokit, a framework I made for connectiong to Weibo on iOS 5

Deelopment wise, Walkin has a little of everything in it. but back to the top level view of Walkin I promised at the start of this page

At its Core Walkin is a customer loyalty program. When our customers check into stores they get points, later they can use those points for rewards that are sent to their door.
