Proof of concept for our Colored Alarm Clock Interface shot @ Dribbble
We've opensourced slider implemented for this shot. Enjoy!
Slider implemented as a subclass of UIControl. You can set its title and max value right in Attributes Inspector in Interface Builder, thanks to @IBInspectable. Also you can choose Slider color using Tint Color property. And there is no need to run simulator to see final result – components are fully rendered in storyboard by @IBDesignable.
Feel free to use this code in your projects and 
Alarm Clock is available under the MIT license.
