You can do this easily by setting your view's layer mask to a CAShapeLayer.

UIBezierPath *myClippingPath = ...

CAShapeLayer *mask = [CAShapeLayer layer];
mask.path = myClippingPath.CGPath;

myView.layer.mask = mask;

You will need to add the QuartzCore framework to your target if you haven't already.

In Swift ...

let yourCarefullyDrawnPath = UIBezierPath( .. blah blah
let maskForYourPath = CAShapeLayer()
maskForYourPath.path = carefullyRoundedBox.CGPath
layer.mask = maskForYourPath
