Thanks.

  - by Alex Trott

  Currently my tableview looks like this: as you can see, cell.textLabel and cell.detailTextLable both load this background, and i can't work out how to get them to stop loading the background, and for it only to be the backing on the cell. Here's my current code to change the cell: - (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath { [cell setBackgroundColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"tableCell.png"]]]; } How can i get round this problem?

• Jump to the start of next statement

  - by Borek

  Say that I'm writing a test and my caret is here (indicated by "|"): [ExpectedException(typeof(InvalidOperationException|))] In Visual Studio 2010, I'd like to press some shortcut that would take me to the next line so that I could start typing "public void Etc()". Right now, I need to press Right arrow Right arrow Right arrow Enter Which is too many key presses IMO. Is there a VS2010 / ReSharper shortcut to aid this operation?

Example: void function(int && i); What is the purpose/benefit of doing it this way rather than simply taking a reference to an object? I assume there is one if it's in boost.
