更改UIPicker颜色

Question

如何更改拾取器的颜色？

我不希望更改字体或文本。我的拾取器是填充的，并且完全按照我想要的方式工作，我想要做的是将颜色从黑色更改为我的自定义白色。

看一下：http://makeapppie.com/tag/uipickerview-in-swift/

如果你想改变每个元素的标题颜色，你可以实现：

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
}

Answer 2

适用于日期选择器和普通选择器的*

   override func viewDidLoad() {
   super.viewDidLoad()
   pickerView.setValue(UIColor.blue, forKey: "textColor")
   pickerView.setValue(UIColor.black, forKey: "backgroundColor")
 }

Answer 3

Swift 4.0

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