Question

I\'m running into trouble trying to blur part of the screen in my iOS app. See image for better idea of what I\'m trying to do.

Answer 1

Have you tried this library:

https://github.com/gdawg/uiimage-dsp

It uses the vDSP/Accelerate framework and seems easy to use.

BTW: 0.01s seems far too quick. 0.03 should do as well.
