Nope, I didn't try CGLayers! By the time I was aware of them I'd already decided that the masking approach made more sense, and was off on a new tangent.

It does sound like a good thing to try for next time. That said, I'm pretty happy with the OpenGL implementation.

Great interview, congrats on the app, it sounds like you put a lot of work into it. I just have one question:</p> <p>When you said you gave up on UIView rendering because the images were drawing too slowly, did you look into using a CGLayerRef? It's basically an on-graphics-chip cache of, well, anything you'd care to render (image, path, composite etc). More detail from apple at: http://developer.apple.com/documentation/graphicsimaging/Conceptual/drawingwithquartz2d/dq_layers/dq_layers.html#//apple_ref/doc/uid/TP30001066-CH219-TPXREF101</p> <p>I know that article isn't iphone-specific, but I followed the example and got a huuuuuge boost to my UIView iphone app's performance.</p> <p>Cheers - Rob (@robfe)</p> Hi Michael.

I know that article isn't iphone-specific, but I followed the example and got a huuuuuge boost to my UIView iphone app's performance.
