Cocoa Custom Changes

Question

How can I get custom mutable views, for example, in the interface builder so that the user can adjust some images with their own

Do I need to manage all this manually using a view that tracks mouse movement, etc.?

Answer 1

You must do all the work yourself. You will need to track the objects in your view, their positions and perform all mouse tracking and viewing updates.

However, this is actually not very difficult, and Apple provided a very complete example in the Sketch Example Code .
