I am using titleForHeaderInSection to show a header for a UITableView section. It worked fine with the iOS6 SDK, but the iOS7 SDK shows the header in all CAPS.
I guess
In Swift,
override func tableView(tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int) { let headerView = view as! UITableViewHeaderFooterView headerView.textLabel.text = "My_String" }
