Your crash is happening because you're releasing something you

function.
Hmm, thanks for the tip. That is how the example I was following was
written.
But I removed the line and it is still crashing on the same line of
assembly code.
Do you think I need to use Create or Copy, alloc or something?
After looking at the example you were basing yours off of I see that
in that example the image was being created by another function
create_image(), in that case (depending on the function
implementation, but probably) you would be responsible for releasing
it. Here though, using the CGImage property of an UIImage, you're not.
What are the values of anim and images before you try to add them to
the animator? In the code portion you posted you don't show where
you're creating your "anim" object.
As well I don't see in my version of the SDK where UIAnimator is
defined. If you're trying to use private API here, don't. Just set the
duration on the anim object directly and add it to your CALayer. You
can get the layer used by a view by sending the layer message to the
view (NS or UI).
