That's actually a more distilled version of my question. When your layer hosting view may be instantiated programatically, or from a NIB; there is no good place that covers both since the -init methods are too early (I haven't needed to test -initWithCoder: yet).
Nor have I determined the boundary condition for which it works afterwards, I suspect it's after the has been placed in the view hierarchy. But if that's the case, does the view hierarchy need to be rooted in a window or can it be floating.
One simple workaround I've been using (but wanted to check for a better solution) is to call -setWantsLayer:YES in -initWithFrame: and layer-back the view's parent in the XIB.
