Removing cell borders from a section of grouped-style UITableView

Question

I have a UITableViewController initialized with the grouped style and having multiple sections. For one of these sections, I'd like its constituent cells to be completely transparent and have no border. I plan to assign a custom view for every row in this section, but having that custom view surrounded by the grouped table cell looks bad :(

The following makes the background color of a cell black instead of transparent... And I still don't know how to get rid of the border.

cell.backgroundColor = [UIColor clearColor]; 

Any pointers? Thanks!

Answer 1

NOTE: This doesn't appear to be working in iOS7 and above. For iOS7 try this answer.

For iOS6 and below, to remove the grouped background from a cell in a grouped table view cell:

This didn't work

cell.backgroundView = nil; // Did Not Work 

This did

cell.backgroundView = [[[UIView alloc] initWithFrame:CGRectZero] autorelease]; 

If you have moved to ARC (I've heard this works, but haven't tested it)

cell.backgroundView = [UIView new];
