title: Getting width of a cell in a grouped UITableView for setting section header width
body: <p>Header says it all really I just need to get at the cell width of the table so I can set my section header width to be the same + a few pixels. Here is semi pseudo-code for my problem.</p>
  
  <pre><code>CustomHeaderView *headerView = [[CustomHeaderView alloc] init];
  headerView.frame.width = [tableView getCellFrameWidth] + 10;
  </code></pre>
  
  <p>Been struggling with this all day. Getting at the width of the cells in a grouped tableview seems like it should be a trivial operation, but for some reason is not. Having said that I'm a complete beginner in IOS programming so if some of you veterans out there could explain to me why this is not trivial that would be awesome.</p>
