For example, you might want to change the slider range to some preset value, or change the track highlight to indicate a valid range. This post describes how you could provide similar touch handling as a UIGestureRecognizer subclass.

However, if the user touches down with the UIControl, drags the control around only in the X direction, and then lifts off the screen, we have a problem. Is your control ready for prime time?

Unfortunately, UIKit does not provide a way to get the disabled version of a tintColor. This works well.
