How to make UIView with AVCaptureVideoPreviewLayer look better?

Question

I'm trying to build a subclass of UIView to quickly take one snapshot by using AVFoundation. It's working great but I would really like to make the corners round or add a little shadow. How can I achieve this using Core Graphics etc.?

Answer 1

Use QuartzCore

#import <QuartzCore/QuartzCore.h>

then you can modify the layer off your the view:

someView.layer.cornerRadius = 8;
someView.layer.shadowOffset = CGSizeMake(-15, 20);
someView.layer.shadowRadius = 5;
someView.layer.shadowOpacity = 0.5;

or something like that
