Getting width of a cell in a grouped UITableView for setting section header width

Question

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.

CustomHeaderView *headerView = [[CustomHeaderView alloc] init];
headerView.frame.width = [tableView getCellFrameWidth] + 10;

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.

The Width of grouped UITableViewCell depends on table width and calculates as

table.frame.size.width/16.0*14.0

I believe it's tableView.frame.size.width/16.0*15.0 – Michael Gray Sep 21 '12 at 00:20

  UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:section]];

CGRect rect = cell.frame;

NSLog(@"Cell width = %f",rect.size.width);

These things are always subject to change, but the width of a UITableViewCell in a grouped UITableView is 300.0 points and has been since iPhone OS 1.0.
