Problem with UITableView clear color

I have a tableview in grouped style. When I set the tableview background color to clear color then I see dark black corners around the tableview. Is there a way to so开发者_如何学运维lve this problem and remove those dark corners?

Any help would be appreciated.

Along with using clearColor, use the following:

[tableView setBackgroundView:nil];
[tableView setBackgroundColor:[UIColor clearColor]];
[tableView setOpaque:NO];

You can set a UIView and set clear color to it. This works for me.

UIView *backView = [[[UIView alloc] initWithFrame:CGRectZero] autorelease];
backView.backgroundColor = [UIColor clearColor];
cell.backgroundView = backView;
