@mertdumenci No, they use CAFilters which are a part of the CoreAnimation rendering process. It touches the FB, but doesn’t do hax to get it

@mertdumenci@conradev CAFilters have never been public. We get CIFilter instead. -

@mertdumenci@conradev layers take CIFilters too on the desktop. Apple haven't ported that over yet to iOS.

@tapbot_paul@conradev@grp UIBackdropView is really really awful API right now. But yes, they need a public version! -
@stroughtonsmith@conradev@grp the only real choices now (AFAIK) are toolbar (no good control) or snapshot+effects (slow as dirt). -
@tapbot_paul@conradev@grp yep! Pretty sure they have a ton of radars asking for this. I wonder if they ever expected it to be so important - View other replies
