AVCaptureDevice Camera Zoom

Question

I have a simple AVCaptureSession running to get a camera feed in my app and take photos. How can I implement the \'pinch to zoom\' functionality using a UIGestureRecognize

Answer 1

Many have tried to do this by setting the transform property on the layer to CGAffineTransformMakeScale(gesture.scale.x, gesture.scale.y); See here for a full fledged implementation of pinch-to-zoom.
