Should I compose a complex UIView with more UIView's or more CALayer's ?

Question

I have a complex view which is composed of a base image overlaid with other images and 2D paths.

I wonder what difference will it make if a assemble the complex view by creating a different UIView for each element and adding them as children of the complex view or if I should instead create a a different CALayer for each element and add them as children of the complex view's layer property.

Thanks

You should elaborate on what you're trying to do, but my rule of thumb is to use UIViews for cases where I am trying to enhance the user interface (user interaction, etc.), and I use layers when I am wanting to animate something or use sprites. It sounds like you are doing the latter, so I would suggest adding new layers to your main view instead of adding sub views.
