What's the difference between UIColor and NSColor, and when would one use each? I came across NSColor while trying to figure out UIColor uses for attributed strings in iOS. I understand the use of UIColor for the UIKit and such, but I don't think NSColor is really useful for this kind of thing. Has NSColor fallen into disuse with regards to iOS programming?
There is no such thing as NSColor in iOS. UIColor is what you should use.
NSColor only exists as a OSX class.
