ios - 更改 UIPicker 颜色

Question

如何更改选择器的颜色？

我不想更改字体或文本。我的选择器已填充并完全按照我想要的方式工作，我想做的是将颜色从黑色更改为我的自定义白色。

如果你想改变你可以实现的每个元素的标题颜色:

func pickerView(pickerView: UIPickerView, attributedTitleForRow row: Int, forComponent component: Int) -> NSAttributedString? {
    let titleData = pickerData[row]
    var myTitle = NSAttributedString(string: titleData, attributes: [NSFontAttributeName:UIFont(name: "Georgia", size: 15.0)!,NSForegroundColorAttributeName:UIColor.whiteColor()])
    return myTitle
}

swift 3:

func pickerView(_ pickerView: UIPickerView, attributedTitleForRow row: Int, forComponent component: Int) -> NSAttributedString? {
    let titleData = pickerData[row]
    let myTitle = NSAttributedString(string: titleData!, attributes: [NSFontAttributeName:UIFont(name: "Georgia", size: 15.0)!,NSForegroundColorAttributeName:UIColor.white])
    return myTitle
}
