override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {

    var name11 = ld.name1
    var name22 = ld.name2
    var name33 = ld.name3
    var name44 = ld.name4
    var name55 = ld.name5


    if indexPath.row == 0 {
        gdvc.detailText.text = name11
    }
    if indexPath.row == 1 {
        gdvc.detailText.text = name22
    }
    if indexPath.row == 2 {
        gdvc.detailText.text = name33
    }
    if indexPath.row == 3 {
        gdvc.detailText.text = name44
    }
    if indexPath.row == 4 {
        gdvc.detailText.text = name55
    }


}

name11 到name55 每一行赋值都是unexpected found nil while unwrapping an optional value
