我使用以下函数来更改字体颜色和字体大小,颜色有效,但字体名称和字体大小拒绝工作.

func pickerView(pickerView: UIPickerView, attributedTitleForRow row: Int, forComponent component: Int) -> NSAttributedString? 

var myTitle = NSAttributedString(string: titleData, attributes: [NSFontAttributeName:UIFont(name: "Arial-BoldMT", size: 45)!, NSForegroundColorAttributeName:UIColor.whiteColor()])

任何帮助？

谢谢.
