Color Picker for iOS

Source includes two controls that work in unison with each other to provide users the ability to pick color in a fashion identical to photoshop.

Designed not to use images or any other external dependencies beyond the classes.

ILSaturationBrightnessPicker

This control presents a saturation and brightness gradient for a specific hue, similar to photoshop's color picker.

ILHuePicker

This control presents a horizontal gradient that displays the entire range of hues. Typically, user would pick a hue, which updates an ILSaturationBrightnessPicker so that they can then pick the saturation and brightness.

UIColor+GetHSB

This category will allow you to access the HSB values of a UIColor easily.

ILView

This is the base view that implements some stuff to make writing custom views a little easier.

Usage

See the enclosed example project. It's pretty straight forward.
