Setting Selection Style BackgroundColor for UITableViewCell Grouped

Question

I want to set the background color of a UITableViewCell when it's highlighted in a grouped tableview. The code I'm using now produces this results. Could somebody please inform me of the correct way to do this, so as to maintain the rounded corners of the uitableviewcell?

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
cell.selectedBackgroundView = [[UIView alloc] initWithFrame:cell.bounds] ;
    cell.selectedBackgroundView.backgroundColor = coolBlue ;
}

Updated Code:

cell.selectedBackgroundView = [[UIView alloc] initWithFrame:cell.bounds];
cell.selectedBackgroundView.backgroundColor = coolBlue;

UIBezierPath *rounded = [UIBezierPath bezierPathWithRoundedRect:cell.selectedBackgroundView.bounds byRoundingCorners:UIRectCornerTopLeft|UIRectCornerTopRight cornerRadii:CGSizeMake(8.0f, 8.0f)];

CAShapeLayer *shape = [[CAShapeLayer alloc] init];

[shape setPath:rounded.CGPath];

cell.selectedBackgroundView.layer.mask = shape;
rounded = nil;
shape = nil;

Update:

Answer 1

By Using Bazier Path you can able to give top two or bottom two or any numbers of corner radius(out of 4 obviously).

Here I am setting top left and top right corner for cell backgroundview:

UIBezierPath *rounded = [UIBezierPath bezierPathWithRoundedRect:cell.selectedBackgroundView.bounds byRoundingCorners:UIRectCornerTopLeft|UIRectCornerTopRight cornerRadii:CGSizeMake(8.0f, 8.0f)];

CAShapeLayer *shape = [[CAShapeLayer alloc] init];

[shape setPath:rounded.CGPath];

cell.selectedBackgroundView.layer.mask = shape;
rounded = nil;
shape = nil;  
// you can change the code as per your need

And now you just want to set the corner for first and last cell background.

And Remember to add QuartzCore Framework in your project and #import <QuartzCore/QuartzCore.h> in your class.

you can change the textcolor of textlable when highlighted using:

cell.textLabel.highlightedTextColor = [UIColor blackColor];
