UIPickerView won't allow changing font name and size via delegate's `attributedTitleForRow...`

Question

I use the following func to change the font color and font size, the color works but the font name and font size refuse to work.

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()])

any help?

Thx.

I have a another option may be it helpfull for you..

Do all work that need for normal picker view : for more help UIPickerView make in Swift iOS

Now follow this step : - you can use method of viewForRow like this

func pickerView(pickerView: UIPickerView, viewForRow row: Int, forComponent component: Int, reusingView view: UIView!) -> UIView
{
    var pickerLabel = UILabel()
    pickerLabel.textColor = UIColor.blackColor()
    pickerLabel.text = "PickerView Cell Title"
   // pickerLabel.font = UIFont(name: pickerLabel.font.fontName, size: 15)
    pickerLabel.font = UIFont(name: "Arial-BoldMT", size: 15) // In this use your custom font
    pickerLabel.textAlignment = NSTextAlignment.Center
    return pickerLabel
}

Updated Swift 3

func pickerView(pickerView: UIPickerView, viewForRow row: Int, forComponent component: Int, reusingView view: UIView!) -> UIView
{
    let pickerLabel = UILabel()
    pickerLabel.textColor = UIColor.black
    pickerLabel.text = "PickerView Cell Title"
    // pickerLabel.font = UIFont(name: pickerLabel.font.fontName, size: 15)
    pickerLabel.font = UIFont(name: "Arial-BoldMT", size: 15) // In this use your custom font
    pickerLabel.textAlignment = NSTextAlignment.center
    return pickerLabel
}

Updated Swift 5

func pickerView(_ pickerView: UIPickerView, viewForRow row: Int, forComponent component: Int, reusing view: UIView?) -> UIView
    {
        let pickerLabel = UILabel()
        pickerLabel.textColor = UIColor.white
        pickerLabel.text = "PickerView Cell Title"
        // pickerLabel.font = UIFont(name: pickerLabel.font.fontName, size: 15)
        pickerLabel.font = UIFont.boldSystemFont(ofSize: 20) // In this use your custom font
        pickerLabel.textAlignment = NSTextAlignment.center
        return pickerLabel
    }

May be it help full for you, I also used this in my project.
