I recently published a simple color selector tool for iOS. The project is available for free under the MIT license and can be integrated easily in your iOS apps. It is currently designed to work for iPhone 4, iPhone 4s, iPhone 5 and iPhone 5s form factors. The project has been created with Xcode 5.0 with Base SDK iOS 7. The deployment target is iOS 6.0 which means it works on iOS 6.0, 6.1, 7.0 and above. The code has been tested on iOS simulators for iOS 6.0, 6.1 and 7.0 with 3.5 inch and 4 inch displays.
Here is the link to the Github project: https://github.com/hetalv985/HVColorSelector
And here is a link to the wiki page where you can see the screenshots:
If you have any suggestions or feedback, please feel free to leave a comment.
Note: In case you face a crash when trying to run the project, select the Target in Xcode. Click on General. Go to Deployment Info section and set the ‘Main Interface’ to be either ‘Main_iPhone4’ or ‘Main_iPhone5’ storyboard and then run the app.
