I have a control that goes inactive under some conditions in my iPhone app. I can [setUserInteractionEnabled: NO] on it and it doesn’t respond to touches. Its appearance does not change however. Other environments I am familiar with “grey out” inactive controls. I wonder what is the idiomatic way to hint to the user that the control is inactive.
UIControl(the parent class of all the common controls) has anenabledproperty that you can set toNO.What it does is dependent on which subclass you’re dealing with, and whether you’ve, say, used custom images for the various states.
