How to "rotate" a layer/view (e.g. just like you would in enigmo)

Asked 2008-10-28T07:00:21.067

I know how to move a layer based on touch. But I would also like to be able to rotate the image.

Is there any sample code that shows how to do this? Or can anyone give me some advice?

Thanks!

I ended up doing it like this:

CGAffineTransform transform = CGAffineTransformMakeRotation(angle);
[[self viewWithTag:999] setTransform:transform];

Note that the angle is in radians.
