UIPickerView不允许通过委托的“attributTitleForRow ...”更改字体名称和大小 [英] UIPickerView won't allow changing font name and size via delegate's `attributedTitleForRow...`

问题描述

我使用以下func来更改字体颜色和字体大小，颜色工作，但字体名称和字体大小拒绝工作。

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()])

有任何帮助吗？

Thx。

： - 您可以使用 viewForRow 的方法

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
}

帮助充分，我也在我的项目中使用这个。
