Work with iphone camera -


i looking can create source , tutorial me answer how create transparent straight line on iphone camera.

please , if knows of tutorial pls reply me.

if understand correctly, want have live preview of camera overlays more or less transparent line, right ? 2 solution come mind: build 1 view gets camera input via avfoundation framework , build - transparent - view holds whatever elements want display on top of that.

another solution build 1 opengl view, use camera input texture background rectangle filling whole screen , render other content on top of that.
