Image processing resources on Mac with objective-c

Question

Can anyone suggest good image processing tutorials/books to start, on Mac using objective-c?

Answer 1

That depends on what you mean by "image processing." For basic manipulation, see NSImage class and the Cocoa Drawing Guide. For advanced topics, see the Core Image Programming Guide.

Answer 2

If you want to experiment with Core Image, use the Quartz Composer application to write your GL shaders. You'll be able to see the effects of changes to your code instantaneously.
