I am creating an Application that contains multiple Images all stacked together. The Application moves those Images frequently, so I am trying to pack them into one big container. Moving this container (of course) causes the Application to lag.

I have tried packing mutiple UIImageViews into one UIView (not a good idea) and packing multiple CALayers with an Image on each one into one big CALayer (still not really helpfull).

So what I am looking for is an option to stick multiple Images (like a puzzle) into one CALayer. I don´t need to reposition those images, since I am just moving the main Layer.

Thanks for any help!

    well, one easy way would be to draw them yourself:
    have your own custom subclass of CALayer and implement drawContext

    set needsDisplayOnBoundsChange so you tell CA that you need to draw stuff yourself
