Résumé de la séquence

This video presents «ColorChart», an application that must run on both small and large devices. Its objective is to let you display a color characterized by its RVB code (expressed in terms of percentage of the basic colors). You may also save a color and fetch it back. Finally, a "web mode" restricts the user to deal with steps of 10% only.

This exercise must be implemented with Objective-C and Storyboard.

Keywords : iOS, iPhone, iPod, iPad, UIButton, UIView, UISlider, UIStepper, UIColor.
