I'm using the normal scheme for capturing a photo - a UIView subclass with AVCaptureVideoPreviewLayer as its layer for showing the preview. Once the user takes a photo, the preview view needs to be removed but still available in case the user would like to take another photo.
The question is what would be the best approach for optimizing the hide/show of the preview view while keeping to minimum the related setup&configuration steps. Is switching the preview view's hidden property a good idea? Should I also stop the session run when the preview view is hidden? etc.
