Well that much I know. And I also know that many NS/UI-things (which use Objective-C) often have a CF-counterpart, which uses plain C and often these are toll-free bridged. The latter kind is typically used when one needs more options or finer control. (E.g. NSDictionary / CFDictionary).
But what is the story behind NS/UIView relative to CIImage, CGImage? When to use what? What are the relevant advantages?
I would really like to get some link to some documentation, which explains these questions.
Kind regards,
Gerriet.
