I want to have a NSDictionary that maps from UIViews to something else.

However, since UIViews do not implement the NSCopying protocol, I can’t use them directly as dictionary keys.

    You can use an NSValue holding the pointer to the UIView and use this as key. NSValues
    are copyable. but, if the view is destroyed, the NSValue will hold a
    junk pointer.
