Display extra info on top of Camera View

Targets iOS
1

Does anyone know how to display some extra information (Label, canvas) on top of the iosCamera View?
So I mean on top of the live view itself.

Thanks in advance.

The only way to do this currently is with declares. You can use my AVFoundation module in iOSKit. There is a limited example included with the project.

Are there CALayers in iOS? You’d still need declares, but you could set-up a CALayer with a CGImage (I’m guessing UIImage also) and append that CALayer on top of the camera view.
