You can download Cheddar for iOS free on the App Store.
Run the following commands to get start:
$ git clone https://github.com/nothingmagical/cheddar-ios.git $ cd cheddar-ios $ rake setup
Now open the Xcode project and build. You will see one error telling you to fill in your API credentials. If you don't already have API credentials, head over to the Cheddar developer site.
This is open source since the app is free already. It is indended to be a source of sample code for everyone to benefit from. You can make cool apps that use Cheddar and I hopefully get more users because you built something awesome.
Also, if you want to help out and fix some bugs, I'll love you forever. Maybe you'll even get a shirt or something :)
Cheddar for iOS is released under the Simplified BSD License.
While it is not strictly forbidden by the license, I would greatly appreciate it if you didn't redistribute this app exactly the way it is in the App Store. There's nothing stopping you, but don't please be a jerk.
If you want to fix bugs, I'll love you forever! If you want to add some features, I may not merge it. I'm sure it will be awesome, but defending Cheddar's simplicity is my upmost duty. If you're feeling like implementing a feature, check out the issues for things tagged with "feature".
