可以修改UISearchbar TextField的高度吗？

    override func viewDidAppear(animated: Bool) {        super.viewDidAppear(animated)        for subView in searchBars.subviews  { for subsubView in subView.subviews  {     if let textField = subsubView as? UITextField {          var bounds: CGRect     bounds = textField.frame     bounds.size.height = 35 //(set height whatever you want)         textField.bounds = bounds         textField.borderStyle = UITextBorderStyle.RoundedRect//         textField.autoresizingMask = UIViewAutoresizing.FlexibleWidth | UIViewAutoresizing.FlexibleHeight         textField.backgroundColor = UIColor.redColor()//         textField.font = UIFont.systemFontOfSize(20)     } }        }    }
