Adding Rounded Corners to only top of UITableView?

Question

I am trying to add rounded corners to only the top corners of my UITableView but the problem is, with the code below, it just makes a black layer over my whole UITableView. How would I fix this?

//Rounded Corners for top corners of UITableView
UIBezierPath *maskPath = [UIBezierPath bezierPathWithRoundedRect:thetableView.bounds 
                                               byRoundingCorners:UIRectCornerTopLeft
                                                     cornerRadii:CGSizeMake(10.0, 10.0)];
UIBezierPath *maskPath2 = [UIBezierPath bezierPathWithRoundedRect:thetableView.bounds 
                                               byRoundingCorners:UIRectCornerTopRight
                                                     cornerRadii:CGSizeMake(10.0, 10.0)];
// Create the shape layer and set its path
CAShapeLayer *maskLayer = [CAShapeLayer layer];
maskLayer.frame = thetableView.bounds;
maskLayer.path = maskPath.CGPath;

CAShapeLayer *maskLayer2 = [CAShapeLayer layer];
maskLayer.frame = thetableView.bounds;
maskLayer.path = maskPath2.CGPath;

// Set the newly created shape layer as the mask for the image view's layer
[thetableView.layer addSublayer:maskLayer];
[thetableView.layer addSublayer:maskLayer2];

the following code works for me for a navigationbar, just change the first line and put your self.tableView:

CALayer *capa = [self.navigationController navigationBar].layer;
[capa setShadowColor: [[UIColor blackColor] CGColor]];
[capa setShadowOpacity:0.85f];
[capa setShadowOffset: CGSizeMake(0.0f, 1.5f)];
[capa setShadowRadius:2.0f];  
[capa setShouldRasterize:YES];


//Round
CGRect bounds = capa.bounds;
bounds.size.height += 10.0f;    //I'm reserving enough room for the shadow
UIBezierPath *maskPath = [UIBezierPath bezierPathWithRoundedRect:bounds 
                                               byRoundingCorners:(UIRectCornerTopLeft | UIRectCornerTopRight)
                                                     cornerRadii:CGSizeMake(10.0, 10.0)];

CAShapeLayer *maskLayer = [CAShapeLayer layer];
maskLayer.frame = bounds;
maskLayer.path = maskPath.CGPath;

[capa addSublayer:maskLayer];
capa.mask = maskLayer;

I think the best way to make a background view for the table view which view has rounded top corner.Its just a solution to solve the problem.May be it will help you.
