Stuarts example for rounding specific corners works great. If you want to round multiple corners like top left and right this is how to do it

// Create the path (with only the top-left corner rounded)
UIBezierPath *maskPath = [UIBezierPath bezierPathWithRoundedRect:imageview
                                               byRoundingCorners:UIRectCornerTopLeft|UIRectCornerTopRight
                                                     cornerRadii:CGSizeMake(10.0, 10.0)];

// Create the shape layer and set its path
CAShapeLayer *maskLayer = [CAShapeLayer layer];
maskLayer.frame = imageview.bounds;
maskLayer.path = maskPath.CGPath;

// Set the newly created shape layer as the mask for the image view's layer
imageview.layer.mask = maskLayer;
