Back in 2008, I made a simple iPhone app called Habits to help me remember to do some recurring tasks that were not a regular schedule. I made a few updates early on, but it basically did what I needed it to do, so it’s been a while since I have looked at it.
A couple of weeks ago, I decided to refresh its look in anticipation of iOS 7. Unfortunately, an app compiled with iOS 6 doesn’t automatically pick up the new look — at the very least, you need to recompile. Instead, I decided to design something custom that would look good now and feel at home on iOS 7. While I was at it, I updated the icon using the iOS 7 app icon grid.
You can see some screen shots on the Habits documentation page, and if you want to buy it, Habits is 99 cents on the App Store.
Here’s a full list of everything that I had to do for 2.0 in case you’re a developer with an older app and want to see what you might be in for.
- Converted to an ARC app
- Moved lots of properties to auto-synthesize
- Updated deprecated APIs to iOS 6.0 versions
- Skinned the tables, mostly with custom cells
- Added a pan gesture to the front-page cells (try moving them to the left for a short-cut)
- Supported local notifications and badges (requiring a new settings page)
- Made a new icon
- Updated my Google Toolkit unit testing to Xcode built-in unit testing (which was gratefully, very easy) — the main issue is dealing with unit-testing’s idea of the document folder
- Updated all button and default images
- Updated in-app help
- Converted my svn repository to git
- Added database migration to support the settings (this app uses sqlite API directly)
- Refactored a lot of code, mostly in the database, view controllers and custom cells, to share more code.
- Fixed a bug in the calendar to support iPhone 5 size better.
- Updated App Store listing, web page, made this post, etc.
