Is it ok to change userInteractionEnabled property in another thread?

This might be a noob question, but I want to change the userInteractionEnabled property of开发者_开发技巧 a view in a thread that is not the main thread, is this safe to do?

Any interaction with UIKit should be done in the main thread. That includes interaction with a UIView.

CORRECTION:

Some interactions with UIKIt are permissible in the main thread. UIImage, UIColor, UIFont and Core Graphics are all threadsafe.
