how to set cornerRadius for only top-left and top-right corner of a UIView?

Is there a way to set cornerRadius for only top-left and top-right corner of a UIView?

EDIT:

I tried the following, but it end up not seeing the view anymore. Anything wrong with the code below?

UIView *view = [[UIView alloc] initWithFrame:frame];

CALayer *layer = [CALayer layer];
UIBezierPath *shadowPath = [UIBezierPath bezierPathWithRoundedRect:frame byRoundingCorners:(UIRectCornerTopLeft|UIRectCornerTopRight) cornerRadii:CGSizeMake(3.0, 3.0)];
layer.shadowPath = shadowPath.CGPath;
view.layer.mask = layer;

Not directly. You will have to:

  1. Create a CAShapeLayer
  2. Set its path to be a CGPathRef based on view.bounds but with only two rounded corners (probably by using +[UIBezierPath bezierPathWithRoundedRect:byRoundingCorners:cornerRadii:])
  3. Set your view.layer.mask to be the CAShapeLayer
