select-region

I'm trying to use the select and copy feature of the IKImageView. If all you want to do is have an app with an image, select a portion and copy it to the clipboard, it's easy. You set the copy menu pick to the first responder's copy:(id) method and magically everything works.

However, if you want something more complicated, like you want to copy as part of some other operation, I can't seem to find the method to do this.

IKImageView doesn't seem to have a copy method, it doesn't seem to have a method that will even tell you the selected rectangle!

I have gone through Hillegass' book, so I understand how the clipboard works, just not how to get the portion of the image out of the view...

Now, I'm starting to think that I made a mistake in basing my project on IKImageView, but it's what Preview is built on (or so I've read), so I figured it had to be stable... and anyway, now it's too late, I'm too deep in this to start over...

So, other than not using IKImageView, any suggestions on how to copy the select region to the clipboard manually?

IKImageView resize is blocky

I am putting an image into an IKImageView, and immediately sizing it to fit. Whenever I do this, the image originally appears at 1-1 size (huge) and then resizes down, which would be fine if the animation was smooth. However, the animation looks ... fluttery? There are big blocks, like 2 inches square… >>> More
