Life cycle of iPhone application
2 likes921 views
The document outlines the life-cycle of developing an iPhone app, including: thinking of an idea, researching similar apps, brainstorming features, designing prototypes, coding the app using modular and reusable components, testing it on devices, submitting it to the App Store, marketing it, tracking downloads, and potentially monetizing it. It provides examples of the author's own Social Media Cafe Liverpool app, which is an open source project available for others to use and learn from.
Life cycle of iPhone application
- 1. Life-cycle of an iPhone app John McKerrell
- 2. My Experience Developing professionally for the web for over 10 years Have been developing for iOS for over 2 years Have had 50 apps available on the store
- 3. “...remember the idea, not the man...” * Think of something unique Think of something useful Think of something fun *EVEY HAMMOND, V FOR VENDETTA
- 4. “... but you cannot kiss an idea, cannot touch it, or hold it ...” * Remember an idea is worth nothing until it’s implemented http://dave.is/businesspeople.html “the execution and delivery are what’s key” - Sergey Brin *EVEY HAMMOND, V FOR VENDETTA
- 5. An Idea Build an iPhone app for Social Media Cafe
- 11. Aggregate Thoughts List of Talks Photos from events Description of talk Hashtag results Actions for talk, e.g Facebook & Twitter video, slides sharing Information about events
- 12. Prioritise Version 1 Future Versions List of Talks Information about events Description of talk Photos from events Actions for talk, e.g video, slides Hashtag results Facebook & Twitter sharing
- 13. Make Lists
- 14. Before you start building Things you will need to build an app A Mac Xcode and iOS SDK (optional) An iPhone, iPad or iPod Touch (optional) iOS Developer Program membership
- 15. Before you start designing iOS Human Interface Guidelines HIG provides instructions for common scenarios Goes into detail on how best to create graphics for use in app Gives a set of rules that iOS apps must adhere to

- 20. Design Best to either stick with Apple’s UI or choose something completely different, tend not to mix well Look at other apps, steal learn from their successes and mistakes Free resources are available, icon sets, Photoshop layouts and more. http://glyphish.com/ http://www.teehanlax.com/blog/2010/08/12/iphone-4-gui-psd-retina-display/
- 21. Example: Facebook Mostly uses iOS UI, or iOS inspired elements Colours and graphics from branding
- 22. Example: Balloons! Custom designed graphics throughout Still makes use of standard UI elements such as buttons and text boxes
- 23. Example: Angry Birds Games tend to use more innovative and bespoke UI
- 24. Coding Use a modular approach Especially on this iPhone this is easier because each screen of information will be based on a separate “ViewController” that can be re-used Custom views within the screen can also be broken out into reusable code Whole apps can be template-able and reused
- 25. Coding Lots of existing Open Source code you can use Three20 basis for the Facebook app Tapku popular Coverflow implementation & more http://blog.proculo.de/archives/183-Useful-iOS-Libraries-and-Classes.html
- 26. HierarchyApp Existing codebase built by me in June 2010 Provides an interface onto a collection of items with similar UI to the iPod app Can be configured with simple settings files
- 27. HierarchyApp Provides a very basic item detail screen Either list of properties or displaying an embedded HTML file Expectation is this would be customised for each app
- 28. HierarchyApp Provides a very basic item detail screen Either list of properties or displaying an embedded HTML file Expectation is this would be customised for each app
- 29. 7digital.com Can be customised to create complicated apps Custom lists with more interesting elements Custom item detail, e.g. song player
- 30. 7digital.com Can be customised to create complicated apps Custom lists with more interesting elements Custom item detail, e.g. song player
- 31. SMC Liverpool App Built on top of HierarchyApp Updates content from internet on startup
- 32. SMC Liverpool App Shows list of talks Talks are categorised in multiple ways
- 33. SMC Liverpool App Can drill down through multiple filters to find relevant talks
- 34. SMC Liverpool App For each talk app provides an overview of the talk and a brief bio of the speaker
- 35. SMC Liverpool App Various actions are offered, all defined in the simple datafiles
- 36. SMC Liverpool App Links open in embedded web browser Further actions available to the user including opening link in Safari
- 39. finished!
- 41. Getting onto devices You did sign up to the iOS Developer Program didn’t you?
- 42. Getting onto devices Collect UDIDs
- 43. Getting onto devices Generate Development & Distribution certificates Install from Xcode directly onto your own device, allows debugging while the app is running Ad-hoc installation allows you to email to other people and let them install via iTunes Limited to 100 devices per account, per year
- 44. Getting onto the App Store Generate App Store provisioning profile Log into iTunes Connect and create an entry for the app Enter Name, Description, Keywords, etc. Keywords can only be entered while submitting a new version of an app, everything else can be edited any time
- 46. Getting onto the App Store Submission now quite easy, in Xcode: Build & Archive -> Submit ... unless your app has a space in the name, e.g. “Chess Viewer”, “Maths GCSE”, “Driving Test” In this case zip the .app file, remove space from filename, use Application Loader to submit
- 47. wait 7-10 days
- 48. hope
- 49. Market your app
- 50. Market your app
- 51. Apple Approves
- 56. Make Money! Apple take a 30% cut in the US but 40% in most other countries including EU & UK
- 57. Make Money!
