Hi Keith, Whilst I was putting together something recently (it's on my blog is you want to see the code) but ended up with the ability to add the layers in -awakeFromNib because the view will always be defined in advance. However I essentially ended up having to call -setWantsLayer: on my view and on the parent view as two calls because the parent view didn't always seem to pass the layer-backing on down to my view. I thought that adding layer-backing in -initWithFrame: worked (you might need to add a layer at the same time) and I think you'll get away with calling it in both -initWithFrame: and in -awakeFromNib without any problems. At the very least you could check in -awakeFromNib to see if the view is already layer-backed and only call setWantsLayer: if it is not.
