Dynamic Issues
Ok so i've been using this pretty much from day one, now i have a project which is using UIInterpolatingMotionEffect to move an image (like iOS7 wallpapers) but if i want to display a blur view over the top, even with dynamic on it doesn't seem to pick up the movement of an image so the blur view is never updated.
That seems likely. FXBlurView doesn't capture the presentationLayer, only the modelLayer, so any animations happening behind it are not correctly included.
I have yet to find a workaround for this unfortunately. Trying to capture the presentationLayer leads to other bugs, such as content in front of the blurView appearing in the blurred image.
Ah thats a shame, it does suck a bit, because it would look awesome if it worked, I'll keep my fingers crossed and hope that in the future you'll find something, or apple release the blur as a xcode feature, thanks.
